Design of switching two ISP and HSRP/VRRP

• Design of switching between Nexus7K and active / standby firewall

  In the attached diagram, Nexus7K is used in two ways: on the left side, pair NX7K connects to the firewall as layer 2 trunks. vPC VLAN are shared through resources. The firewall is a pair in Active mode / standby. On the right side, another pair of NX7K connects to the firewall as layer 3 rotued links. HSRP or VRRP is running between the pair of NX7K for firewall VLAN SVI.

  Because even NX7K have mesh connections to the active firewall units / standby, I want to make sure in failover scenarios (failover firewalls or failures of NX7K), the link that remains between the pair of NX7K and the firewall can actually send traffic (not perforated black).

  Failure scenarios I can think of include: Firewall active failover on the eve, failure of the main device NX7K, double NX7K active and failure of peers-link NX7K vPC. I would like to get some advice on what I should consider and implement in these scenarios to achieve high availability.

  Many thanks for any advice.

  Hello

  your topology, I see that the main problem is that the physical connectivity from the firewall to the pair of devices nexus in topologies to fails to a redundant link to the N7K

  first since you're using vPC with one counterpart vPC linking the pair of N7K then you must follow the recommendations of Cisco firewalls of L2 and L3 link connection

  L2 if you pass vPC vlan on the trunk in your topology and firewall then there is a possibility of blocking traffic or drop cases underwritten by vPC loop prevention mechanism in the case for example a vPC counterpart link gose down

  the fix to the East either:

  use no-vPC VLAN and link to switch separate inter for VLANs (i thin that you already have this link)

  or multi home L2 connects each firewall for the two switch N7K and assuming that HSRP is configured in the N7K and static routing is used between the firewall and the N7K

  for links to L3 Firewalls:

  You must stream as well (if possible and recommend) and use a static routing between N7K and firewalls and firewalls must point to the VIP of HSRP N7K

  multiple L3 and L3 dyanaminc routing peering on the link of the vPC-peer is not supported design

  Look at the discussion that might help as well

• I have a design program on my iMac and Air. I want to transfer a file between the two, but it's in a format that it cannot open any applications. Can I transfer it somehow between the two?

  I have a version software Punch Home Design compete 17.5 on both my iMac and my Air.It saves files in my office as a .dxf file. I want to transfer the file to my Air, but nothing opens a .dxf file, including the Dropbox App Home Design is without help. Is it possible to just connect the two computers and share the file? It offers 3D features that I want to show a customer without making them come to my office and look at my big mac. The two computers are on 10.11.3, so what counts.

  I don't understand how a program that works and which saves .dxf files can open them but CADintosh can open the .dxf files.

• Can I have load balancing for two ISP (PPPoE and PPPoA) on Cisco 897va connections

  Hello

  I have two ISP connection and I have Cisco router 897va, I want to have the load balancing for two ISP connection second connection is PPPoE connection and second is PPPOA (ATM) connection.

  It is possible to do?

  Thank you in advance.

  You can balance by TCP (the default behavior with CEF enabled) stream.  Alias a user turns off a pipe and the next user goes off the next pipe.

  Make sure that you use the nat with route map that matchers the output interface, then you just need two routes of equal cost default (a leaver each circuit).

  Hello

  The Intel graphics chip, which is part of the central unit should be used for low performance applications, because it allows you to save energy and reduce the internal temperature.

  For best performance while game, it s advisable to use the external GPU (nVidia or AMD)
  This setting can be changed in the nVidia control panel s

  Here, you should choose manage them 3D settings (can be found on the left in the nVidia control panel)

  Now in the main window, you will find two global settings and program parameters tabs
  In the program settings tab, select the (game) program that needs to use the nVIdia GPU

  If it is not listed, click the Add button
  Then choose the graphic processor preferred for this program (generally must be nVidia processor high performance)

  Last but no less, in this program-specific settings, you can assign additional features to improve performance.

• HA Dell two, Sonicwall for two ISP links configuration

  Dear experts,

  I have two Dell SonicWall NSA3600 with two ISP links.

  Currently one that nsa3600 with two links ISP uses with configured load-balancing feature.

  Now I want to configure hardware failover using NSA3600 secondary.

  I know how to configure hardware failover with NSA3600 unique using two Internet service providers.

  But I have no idea about 'How to configure hardware failover for two NSA3600 with two Internet service providers.

  You have an idea on that?

  Thank you.

  Warm greetings,

  Zaw

  Hi Zaw,

  According to my understanding of the question you posted "How to configure hardware failover for two NSA3600 with two Internet service providers. »

  If so there is no special configuration is required. It will be like the regular HA installation. the 2nd Internet service provider, you need a switch connecting the two NSA 3600.

• Double connection ISP and load balancing

  Hi all

  I have the Cisco 2911 router k 9/s with 3 GB ports. I have also two different ISP connections, all have two different available bandwidth (one is asymmetrical, else a symmetrical).

  What I want to achieve is to ensure the balance of Nice load between two ISPS for all PCs behind the NAT device.

  What I know so far, it's that I can use CEF or PfR/REL. For both of this technology, I have some doubts.

  CEF: distributes the network load between the two connections based on sessions (which is good, because I strongly to use tools like Skype or Lync for audio/video conversations). However, what is happening, when I get on one of the ISP connections broadband bandwidth max? He's going to choke for 50% of the connections? Or it will detect the use of bandwidth and to force using second ISP?

  PfR/REL: as far as I understood it resolves my concern regarding the use of the connection, but what happens to the session? Should it also be based on this mechanism? As you know that it is very important for audio/video connections.

  Are there other tools that can provide these load balancing? I know DAB, but I don't want to decide manually, where each service (e.g. http or ssh) will have to go. I'm looking for something more automated.

  Thanks in advance for any help.

  Hello

  I assume that you have a static route for the subnet 213.192.65.0/24 on top of the output and with the combination of order

  network default IP 213.192.65.105 213.192.65.105 IP address is installed as a default gateway. What is the #2 ISP?

  If so, it explains why he always goes on ISP2 only.

  http://www.Cisco.com/en/us/Tech/tk365/technologies_tech_note09186a0080094374.shtml#flagging

  Just remove the config:

  Noneip default-network 213.192.65.105

  Noneip default-gateway 213.192.65.105

  Then again check the routing table:

  SH ip route

  Hope it helps.

• Can I install photoshop on my two desktops and my laptop?

  Can I install Lightroom & Photoshop on my two desktops and my laptop?

  Install and activate are two different things.

  You can install the software on as many computers as you want.

  However you can activate the software to be used on up to two computers at the same time.

  You can switch power on and off activation via Help > Sign Out (and help > Sign In)

  In other words, you can alternate two activations between three computers according to the computer on which you use both. The software won't let you activate the 3rd until you disable one of the other two.
