OSPF and redundancy

• Redistribution of Routes between OSPF and EIGRP

  We have a network of test with the topology below.  We have two networks connected to a L3 switch.  Both networks have an ASA firewall with a tunnel from site to site between them.  They also have a connection in conjunction with each other.  We want to implement a scenerio where the concert connection is the main route but if that route fails, then it switches to the routethat is above the tunnel from site to site.  We have eigrp running on two basic switches so that the roads on the concert connection function properly.  However Networking cannot be learned on the second road that goes over the vpn tunnel.  We have running ospf on the asa and we are redistrubuting routes in eigrp.  Which apparently correct?  Look like the SAA they learn on ospf routes correctly however when we go to basic switches and show ip eigrp topology we do not see the routes possible successor.  Any ideas on how to make this work?

  

  Hello

  The initial Setup looks that you have summarized automatic enabled on core switches, also to the asa eigrp process your redistribution measures doesn't look right about the delay/load/reliability-whats the reasoning behind this? Could you try the following:

  Switch main 1 & 2

  Router eigrp 100

  No Auto-resume

  ASA 1 & 2

  Router eigrp 100

  Redistribute ospf 1 100000 1 255 1 1500 metric

  Could you also post the out-of - show ip eigrp topology all-links

• OSPF and balancing

  Hi all

  I have 2 - E1 links from place A to place b. I am running OSPF in the network.

  For both the serial interface, I gave cost ospf as 100.

  How can I configure loadbalancing over links series that takes place in OSPF?

  Is - is my setup load balancing?

  How to verify that OSPF is loadbalancing links?

  Hello

  You need not specifically configure OSPF to balance the load too long that the two links have the same administrative distance then your peer routers will learn the same routing information from two different IP addresses that are the opposite of your E1 links.

  To check if you are balancing you can use 'show ip route '.

  The following example uses EIGRP but this will output similar to OSPF with different codes and distance from the admin:

  D [90/289536] 192.168.72.0/24 through 10.48.1.2, 1w2d, FastEthernet4/1/1

  [90/289536] through 10.48.1.6, 1w2d, FastEthernet0/1/1

  You can see that 192.168.72.0/24 is announced two IP addresses.

  You can do per package or per destination load balancing, I think that by default on a fast router switching is enabled, which means the load balancing is done by destination. If you want to package you can disable the quick change on the interface in question using "no ip route-cache".

• TMS 14.5 and redundancy with F5 load balancing

  Hello

  I'm looking in the installation guide for TMS 14.5 to design redundancy TMS with the F5 for one of my clients. I wonder if there is any requirement of specific network for the TMS1, TMS2 and F5 must be in the same VLAN or not. My client have a TMS with TMSPE and deploy the TMS Server 2nd in different data center and will use existing F5 load balancing. They cannot have the same VLAN as a current TMS server in the new data where 2nd MSDS server will be Center. Existing F5 load balancing is also, in the VLAN different already.

  y at - there no specific review we need to take care of the redundancy?

  Thank you

  Chris

  As the TMS 14.4, TMS no longer an active/active load-balanced mode and now works as active/passive.

  You can find the details in the "Configure a redundant deployment" section of the Installation of TMS and Upgrade Guide (latest version 14.6 related).

  As long as both devices are accessible (and your F5 can route traffic to each of them according to the needs), it does not matter what VLAN, subnet or a location that each MSDS server resides on.  Information of VLAN in the guide are just one example of how it can be configured in a simple load balancing scenario.

• Cumulative level 1 backup and redundancy of information

  My understanding of Cumulative level 1 - backups all the block changed since last level 0 backups and also double level 1 incremental copies, if we missed any level 1 differential before running the level 1 cumulative backup.

  Having said that I fell on the underside of documentation in Oracle.

  Suppose a case where REDUNDANCY is 1 . You run a backup of level 0 at noon Monday, a level 1 cumulative backup on Tuesday and Wednesday at noon and a backup of level 0 at noon Thursday. Immediately after each daily backup, you run a DELETE OBSOLETE . Wednesday DELETE command does not remove the level 1 of the Tuesday backup because the backup is not redundant: the level 1 of Tuesday backup could be used to recover the level 0 backup Monday for a duration between Tuesday noon and Wednesday noon. However, the DELETE command Thursday removes the previous level 0 and level 1 backups.

  Can someone explain to me why killing level 1 backup needed clarification? When we have a backup of the sea element that has backup KILLS (e i, which has backup LUN)

  to recover the database so I think that a single backup item is needed Wednesday.

  Please correct me if I'm wrong. Sorry for my bad English, if you find any grammatical error

  Also put me as what will contain the element of KILLING level 1 cumulative backup

  for sample data of level 0 kills more than Monday morning and data MIDI Mar

  Thank you

  No backup of level 1 will contain nothing of the previous level 0 backup. First level 1 (no matter the cumulative or differential) will contain only the data blocks that have changed since the previous level 0.  Backups.will all new 1 cumulative level contain only data blocks that have changed since the previous level 0.

  And if you think a little about it, which will answer any other questions.

• Analyze the index on the machine of Dataguard and redundancy of ASM disks

  Dear friends,

  I have two questions regarding disc Dataguard and ASM.

  (> > 1) for best performance, periodically, we rebuild the index index and analysis analyze table. What is the best periodic steps to do to get better performance?

  I mean, first of all is rebuilding of index, is second index analysis and so on......

  (> > 2) if I run analyze the index or the table on my PRODUCTION system he replicated this effect on statndby dataguard automatic system? If so, how it is replicated?

  (> > 3) my last question related with high redundancy of the ASM disk. I have some confusion on this area.

  Let's say I have 10 disks in a diskgroup '+ DATA' and I did 'HIGH' level redundancy, means 3 way redundancy. Here I know 3-way the redundancy, it writes data on 3 discs at a time. But what of the other 7 discs. In fact, I need to know the mechanism of writing?

  -Each disc is identical to the other drive?

  -For HIGH redundancy, how many disk failure can be tolerated for any loss of data?

  Waiting for your kind reply......

  "on my PRODUCTION'---> you mean"on my FIRST.

  Yes, the data dictionary is updated when you run dbms_stats.gather% and updates data dictionary are through recovery that applies to the WAITING for more.

  NOLOGGING surgery would not be applied to the expectation (the index would be marked corrupted to the standby) unless you have set on FORCELOGGING.

• VMware, NAS and redundancy

  Hello

  We will set up a new environment and think about a ReadyNAS and two machines as guests of vm. I'm on the right track when I think of vCenter it is necessary here to be able to move guests between the host computers?

  And is it possible to use it as the failover, which moves all guests to the other virtual machine host if one of the machines crash? And it is also a part of vCenter?

  Is this a good setup for some computers invited for a small business with two hosts of vm for redundancy?

  Thanks in advance!

  I'm on the right track when I think of vCenter it is necessary here to be able to move guests between the host computers?

  Yes - the Victoria Cross is the tool that allows migration (vMotion) Hot of the VMs - without it, you can move virtual machines between host computers, but it will be a rather arduous manual process. . and require downtime.

  And is it possible to use it as the failover, which moves all guests to the other virtual machine host if one of the machines crash?

  The feature you need here is called HA. What will happen if it is not the machine is "moving" but rather that if the ESX host fails, the VM will be restarted on another ESX host. You need a VC to set this up, but the feature will be contimnue to operate, even if VC crashes.

  And it is also a part of vCenter?

  Yes - it is set up by the CR (but not dependent on this subject)

• Patching Embedded ESXi 3.5 and redundancy

  Hello

  I tried to find answers to theses in the documentation, but failed so far.

  I have a Dell 2950 PowerEdge server with ESXi 3.5 embedded.   I understand that I can be updated by using the tool VMware Infrastructure Update, installed on a physical server separate.  Where is the update applied? It is applied directly to the memory card Flash shipped?   When to apply?  If it fails, I can just re - apply the 3.5 version via the update tool?   Is there any built-in redundancy, so that if he does not validate successfully, I can just reboot and the old version of ESXi will still be on the map?

  If there are all the sections of ESXi documentation that refer to this, please let me know.

  Thank you very much!

  Welcome to the VMware community forums.   If you mount the USB drive in another operating system, you will see these partitions

  Hypervisor0 - 4 MB

  Hypervisor1 - 47 MB

  Hypervisor2 - 47 MB

  Hypervisor3 - 500 MB (is mounted as /store

  H1 and H2 are where ESXi store its firmware.  H0 has SysLinux, which is the original boot loader.  It will be either boot ESXi of H1 or H2.  When you start with a fresh install, Syslinux will start ESXi of H1 and H2 will be empty.   H1 will be mounted by ESXi as /bootbank and H2 will be /altbootbank.

  When you patch your host, the firmware is written in /altbootbank and the H0 is changed to start from the H2.  The next time you start H2 becomes /bootbank, and H1 is /altbootbank.  When you patch it again reverses again.

  The good thing about this is that easily return you to the previous version.   Press SHIFTR on priming initial screen and you have the option to revert to the previous version, if the host has problems after the upgrade.  ESXi save a backup of your system in /bootbank/state.tgz (for the on-board version local.tgz) configuration.  If you use the SHIFT keyR after a month, any change in config, you made since then would be lost.

• Layer 2 switch decision and redundancy NIC teaming/switch

  Hello

  Imagine that I need to provide a reliable network between two mainframe environment.

  Basically, there is a NIC communication 'intra' between the two chassis. This 'share' NIC could be connected in a switched environment isolated too long which supports 1 GB. The idea is, instead of using a VLAN in our production environment existing to allow communication between the two chassis, people would use a small switch instead, totally isolated from the network to provide such a service of communication intra-NIC between the two chassis. My questions are:

  (a) agree you generally keeping a separate switch (maybe a new layer 2 2900 XL?) I could provide a more reliable environment than if I plug on new servers VLAN into my existing 3750 switch? Note that my switch 3750 in production is not a stackwise. It's just an autonomous one.

  (b) a small 2900XL switch (8 ports?) can do the 1000 MB? Also, I have recommended that we use copper instead of fiber for this.

  (c) in the past I heard people talk about problems with the grouping itself. I wonder if I just use a Gigabit NIC, copper, I either offer. Again, please let me know where the layer 2900 XL switches do not support gigabit.

  Your intuition is very valuable. Thank you.

  Yes, 2960 should suffice in this case your need. It has 24-port and 48-port port 10/100/1000 version as well.

  Think about it an absolute must - manually update your drivers.

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded
  on your system. For each driver in the list, additional useful information is
  Poster: load address of the driver, description, version, product name,.
  company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit Maker as replacements and system manufacturer of device which are
  the most recent. Control Panel - write - graphics card - device manager
  the brand and complete model of your video card - double click - tab of the driver-
  Note the version information. Now click on UPdate Driver (this can do nothing
  MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
  This will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard
  If there are 3rd party with their own software and drivers and the other main device drivers
  you have.

  Now, go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restore)
  and site (Realtek, Intel, Nvidia, ATI, for example) and get the manufacturer and device
  their latest versions. (Look for the system to update the BIOS, Chipset and software updates
  Site of the manufacturer here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN -.
  REBOOT after each installation.

  Always check in the Device Manager - drivers tab to be sure the version you are
  installation actually appears. This is because that some rollback of drivers before the
  later is installed (particularly that audio drivers) so install a driver - reboot.
  Make sure that it is installed and repeat if necessary.

  Repeat to the manufacturers - BTW to the device makers DO NOT RUN THEIR
  SCANNER - check manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
  http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

  Installation and update of drivers under Windows 7 (updated drivers manually using
  the above methods is preferable to ensure the latest drivers from the manufacturer of system
  and device manufacturers are located)
  http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

  If you update the drivers manually, then it's a good idea to disable driver facilities
  in the updates of Windows, which leaves on Windows updates, but it will not be installed
  pilots who are generally older and cause problems. If updates provides a new
  driver then hide it (right click on it) and then go get new ones manually if
  you want.

• ESXI hosts 5-2 and the best way to configure vSwitch and Nic redundancy

  Hi all

  Could someone help me find the best way to configure the vNetwork on 2 5 ESXI host for redundancy.  Once I managed to correctly configure the 2 hosts I will seek to use the same installation process for 6 guests.  3 sites with 2 hosts on each site managed all of vCentre Server

  I have 2 DL380 G7 servers 5 ESXI installed on a class 10, 8 GB SD card, I'm looking to install VSA on the 2 hosts on each server with 4 TB of internal storage (8 * 600 GB 10 k SAS).  Each server has a gigabit integrated 4-port NIC and I installed a 2nd NIC gigabit PCIe 4 ports, I also x 2 16 switches of port with Layer 3 routing.  I use vSphere 5 Standard acceleration Kit I am looking to use vCentre server for managing, vMotion for maintenance, HA for the failover and VM 10/15 (vCentre Server Std, DB SQL to vCentre Server, Exchange 2010, SQL Server 2008 R2, IIS Intranet, Helpdesk, 1 DC, 2 Domain Controller, AV Server, WSUS, SCCM Server, and Terminal Server server).

  What would be the best way to install and configure the network for performance and redundancy and am I missing something?

  My thoughts are, Teaming: -.

  vCenter - vswitch0 - port1 on NIC1 and port1 on NIC 2 - port1 on NIC1 to physical switch 1 - port1 on NIC2 to physical switch 2

  vMotion - vswitch1 - port2 on NIC1 and port2on NIC 2 - port2 on NIC1 to physical switch 1 - port2 on NIC2 to physical switch 2

  HA - vswitch3 - port3 on NIC1 and port3on NIC 2 - port3 on NIC1 physics 1 - port3 on NIC2 to physical switch 2 switch

  VM - vswitch4 - port4 on NIC1 and port4on NIC 2 - port4 on NIC1 to physical switch 1 - port4 on NIC2 to physical switch 2

  or do I need an additional NIC on each server to hit the VM 12-6 VM for 2 ports on 2 NETWORK interface card, or maybe something else I missed?

  Thank you

  In your case, to keep it simple and what I can say here is what would be my recommendation:

  3 standard vSwitches

  vSwitch0:

  • Management - vmnic0, vmnic2

  vSwitch1:

  • vMotion - vmnic1, vmnic3

  vSwitch2:

  • VM network - vmnic4, vmnic5, vmnic6, vmnic7

  The only reason why that I didn't split the VM in other network adapters shipped is because the difference in the types of the DL380 adapter shipped and the PCIe quad.

• advantages and disadvantages of storage iCloud?

  I love the backups and redundancy, but I don't want to be dependent on access to the internet to see things or hear things that used to be on my laptop of desktop machine.  Do I lose access to e-mail messages already received or sent if they are stored in the cloud?  What about pictures?  I think I'm losing the ability to listen to music that I used to have on my machine, if it is in the cloud, but maybe it's because of copy right issues.  In any case, I care more about the email first two, in particular.

  Thank you

  LR

  iCloud is not primarily a backup.  It is intended to keep the documents and data on all your devices up-to-date.  If you use iCloud photo library and change a picture on your Mac, you can see the same changes on your other Mac or your iPhone or iPad. Import a picture on a device, and it will appear on your other devices.  Delete a photo on a device, and it will be gone from all devices.  Your iCloud photo library will be the same on all devices. If you enable the option 'Optimize storage' on one of your devices, this device will store full versions of your photos, only in smaller versions. You can browse photos, but will need an internet connection to edit photos. But without "optimisation of storage", you will have a full copy of your photo library on your device to work and can work with photos on Internet.

  I think I'm losing the ability to listen to music that I used to have on my machine, if it is in the cloud, but maybe it's because of copy right issues.

  With iTunes game, you can keep all your music stored locally as well. With apple Music, you can download the music you want to store for offline listening.

  Your Mac will keep messages Amil, that you have already downloaded there and you can read them offline.

  But remember, iCloud is not a backup. It's your job to central storage. Any change is immediate. You should always keep local backups as well.
