By default static route with recevied BGP default route

• Remove the static route by default

  Hello

  I have a switch L3 which has a static default route pointing to a FW that is connected to a circuit of the Internet. The same L3 switch made EIGRP routers on our MPLS network. If this default static route disappears EIGRP will inject a default route, and users will receive their Internet traffic through the MPLS cloud as a backup.

  My question is how to remove this static road by default with a mechanism that is unique on the Internet circuit. I can't count on line protocol because it almost never goes down. I can't rely on Internet ping IP SLA addresses because if they descended through the Internet channel available on the circuits quickly and create a loop of the SLA of intellectual property.

  I wish I could do BGP with the Internet provider but this circuit is in a country where it would be difficult.

  Any ideas on how to remove this default static route based on something that is unique to this tour of the Internet.

  Thank you

  "I can't rely on Internet addresses ping IP SLA because if they descended through the Internet channel available on the circuits quickly and create a loop IP SLA."

  To remedy this situation, you must add a route with the 'permanent' switch at the end of any IP you track on your IPSLA... In this way, if this interface is down, your ping IPSLA would stop and IPSLA would be the move and change your default route.

  Example:

  Route IP 1.1.1.1 255.255.255.255 2.2.2.2 Permanent

  where 1.1.1.1 is the IP address, you are followed and 2.2.2.2 is your 'usual' default gateway

• SG300-52. Prefer to send traffic to the default gateway rather than static route? Network stops if I disable ICMP redirects.

  I have 4 switches, each act as their own with a 26 subnet mask. They have static routes for every other switch. The firewall has a static route to each switch. If I unplug the LAN of the Firewall interface, traffic stops the flow of the switches. If I block the side LAN firewall, ICMP redirects, traffic stalls outside.

  So if you are connected to this switch, say that you pull an ip address of 192.168.122.20. Your front door is the 192.168.122.62 switch. If you try to access a server 192.168.127.142, the SG300 sends your traffic to 192.168.127.254 to get an ICMP redirect, rather than simply to communicate directly with 192.168.127.50.

  My network 'basic' is 192.168.127.0/24 vlan1 and the firewall is 192.168.127.254

  This is the route of one of my switches table (which has 192.168.122.0/26 and ports run on vlan122)

   Maximum Parallel Paths: 1 (1 after reset) IP Forwarding: enabled Codes: > - best, C - connected, S - static S 0.0.0.0/0 [1/1] via 192.168.127.254, 73:48:13, vlan 1 C 192.168.122.0/26 is directly connected, vlan 122 S 192.168.123.0/26 [1/1] via 192.168.127.123, 73:48:13, vlan 1 S 192.168.124.0/26 [1/1] via 192.168.127.124, 73:48:13, vlan 1 S 192.168.125.0/26 [1/1] via 192.168.127.125, 73:48:14, vlan 1 C 192.168.127.0/24 is directly connected, vlan 1 

  In any case, what gives? Why the switch would first try to send the stream to the firewall?

  EDIT: Here is the server routing table:

   [email protected]/* */:~$ ip route show default via 192.168.127.254 dev eth0 192.168.122.0/26 via 192.168.127.122 dev eth0 192.168.123.0/26 via 192.168.127.123 dev eth0 192.168.124.0/26 via 192.168.127.124 dev eth0 192.168.125.0/26 via 192.168.127.125 dev eth0 192.168.127.0/24 dev eth0 proto kernel scope link src 192.168.127.142 

  Hi Jonathan,.

  I'm sorry. I misunderstood the routing table you want to accomplish. Your concern seems relevant given that the matching rule more will be selected instead of one: page 275 http://www.cisco.com/c/dam/en/us/td/docs/switches/lan/csbms/sf30x_sg30x/...

  ... "When the routing of traffic, the next hop is decided based on the longest match on the prefix (LPM algorithm). A destination IPv4 address might match several routes in the IPv4 static routing Table. The device uses the matching route with the higher, subnet mask that is, the longest match on the prefix. "...

  So go ahead and report it to the support team so the guys can make the laboratory, confirm it and declare additional:

• Help! Static route between two router WRT160NL

  Hi all

  I have my internet connection to connect to my main router from Linksys WRT160NL (192.168.1.1) with 192.168.1.x.

  My 2nd Linksys router to connect to the first gateway as well.
  The 2nd router has the ip 192.168.1.100 WAN and it's a local subnet as 192.168.2.x.

  My 192.168.2.x machines can access the internet and connect to all the machines in the network 192.168.1.x.

  However, the 1.x network cannot access the machines on the network of the 2. And because of that, I can't share or print between two networks.

  I try to add static routes on my main router (192.168.1.1) with the road: 192.168.2.0 mask 255.255.255.0 and default gateway 192.168.1.100

  However, the road does not work yet.

  in any case to ensure that the 1.x network able to access the network 2.x and 2.x access 1.x file and print sharing.

  Thanks for your help!

  Gateway of the router does NAT who made the side inaccessible side LAN WAN, unless you configure port forwarding automatic or similar. If she would not make your LAN 192.168.1 would be accessible from the internet. Static routing will not change that.

  You will need to disable NAT (aka switch to router mode) on the second router. You must configure a static route on the main router then. However, most likely your network 192.168.2 * will not have Internet more because the main router will NAT for 192.168.1. * and no 192.168.2. *.

  If possible set up the second router as access point only and run a LAN.

• Explain SGE2000/P static routing (equal to L2 +)?

  L2 + mean?  I know these aren't L3 switches with IVR capabilities, then what is the purpose to configure static routes, if there is no functionality InterVLAN routing?

  T.I.A.,

  Chris

  Welcome to Cisco Community!

  With get them into a huge discussion, I will try to respond as quickly and directly as possible.

  Our EMS and EMS in the series switches are layer 3 switches (can also be configured as L2) so that they are able to operate as a (inter VLAN) router or gateway for all the VLANS. Once you have created the VLANS and assign an IP address, that IP address will become the GW for this VLAN. Under routing, you will not see any scholarly networks until what you assign the VLAN to a port and the port is enabled. You will then need to configure a default route to send traffic to the cloud. The router must belong to the same VLAN on the switch. So if the switch has an IP address of 172.16.30.1/24, the router will have an IP address of 172.16.30.254/24 for example. The road reads: next hop metric 172.16.30.254 0.0.0.0/0 2 (or higher).

  With respect to the static routes as a switch L2 or L3, that they would be useful when you have a device connected to another switch that is disjoint from your typical network of the local switch. In other words, let's say you have 3 (except default native VLAN 1) VLAN V10 - 30. Everything you devices belong to these VLANs, but you have a server on 30 VLAN that is not connected to this switch. You will then create a static route for the IP address of this server to the remote switch.

  VLAN30: 172.16.30.1 (local EMS)

  Server: 172.16.30.200 (on the remote switch)

  Remote switch: 192.168.20.1 (distance EMS)

  VLAN30: 172.16.30.2 (on the EMS distance)

  Static route:

  hop metric 172.16.30.2 next destination 172.16.30.200 2

  I hope that answers your question. These are really my favorite switches, because I find them very reliable and highly configurable. I love these things.

• What is checked first, GLBP or static route?

  I have 2 routers doing GLBP. The virtual IP address is given to jobs as a default gateway.

  When a packet hits the default gateway, it will go to RTR - A. Then the second package request will go to RTR - B. It's all good via GLBP.

  The question is, if RTR - A is a static route to 66.66.66.66 and the next hop for this destination is via RTR - B, how will RTR - A treat this package when RTR - is the router that needs to deliver the package to the internet? I mean, how is this Treaty?

  GLBP will review the package and then determine what it is RTR - A tour to take it, then it give RTR - A, and then this router will focus on its local routing table and then it give RTR - B because the destination is 66.66.66.66?

  Or the static route will take precedence GLBP? but again, only RTR - A will have this static route entry as the network admin pushes everyting for 66.66.66.66 out of the RTR - B. Confusion is the GLBP thing.

  Thank you for the help

  Hello

  GLBP works on a per-host basis and not per package. I mean, when the host is the gateway for the first time, this is the moment where we decide which router is actually going to be pass packets to the host.

  Consider this example

  Three host X, Y, Z

  Two routers with GLBP RTR A and B RTR operating in the Round Robin database

  1. Boots X host receives the IP via DHCP or configured statically, it will send the ARP request to the gateway. ARP request is served by RTR and he sends MAC address. Host X now use RTR A gateway
  2. Boots of host obtains the IP via DHCP or configured statically, it will send the ARP request to the gateway. ARP request this time is served by RTR B because GLBP is set to be in round robin mode. RTR B sends address MAC to host b. host Y will now use RTR B gateway
  3. Boots of the host Z Gets the IP via DHCP or configured statically, it will send the ARP request to the gateway. ARP request is served by RTR has time and he sends MAC address. Host X now use RTR A gateway

  RTR has accessibility to 66.66.66.66 network RTR B also accessibility features. This package can be transferred.

  X(a) RTR as gateway host sends the packet to 66.66.66.66 going A RTR, which will send to RTR B because of the static route.

  Host Y (RTR B as gateway) sends out packets to 66.66.66.66 going to RTR B, which it will process in accordance with its routing table

  I hope this helps.

• searching for NAT/Firewall/static routing tips

  Hello

  I am very new to vCloud network and security. I've read the documentation, but it can be confusing for me. I am attaching a schema to help provide a context for what I'm trying to achieve. Keep in mind that the IP address has been changed for security reasons. Address ranges are not accurate but for the context.

  We have an org routed with a single VM VAPP, directly connected to the VCC-Net. It is a Linux server. We have a vShield edge device. There is no rule of firewall, NAT, static routes configured. Essentially of deployment costs. The owner of the server wants to be able to connect to a Linux repo for updates/etc.

  For testing purposes, I have disabled the vShield firewall to allow all traffic through. from the Linux server, I was able to ping both addresses assigned to the border of vShield (192.168.1.1 and 10.10.16.17) but I couldn't ping 10.10.2.140. This leads me to believe the vShield Edge does not know how to route packets between 192.168.1.0/24 and 10.10.0.0/16.

  I have read and what I'm gathering is that I have to configure NAT and firewall rules to achieve. I googled everything I can, and now I'm just confused. Can someone please give me some advice?

  VShield Edge routing feature is similar to traditional router. By default, it can discover only directly attached networks and deliver packages, in this case 192.168.1.0/24 and 10.10.16.0/16 are direct networks. So if you need reach any other private network, we need to define a static route (it is not supported / configurable in vshield edges of dynamic routing since then). For Linux VM 192.168.1.10/24 join the public network, set a NAT NAT vShield edge rules and enable the appropriate firewall rules.

• static routing in SMV problem

  This problem may seem out of place in this forum, but I think that the problem is specific to XP virtual machines in ESX. The same issue has not been seen in a similar setup running under XP hosted in ESXi.

  I invited XP with multiple network cards configured. A NETWORK adapter is connected to a 10.4.0.0 network with a 255.254.0.0 mask, which means it's supposed to handle all the traffic 10.4.X.X and 10.5.X.X. However, I have another NIC that is connected to 10.5.217.0 with a 255.255.255.0 network mask. XP runs without problem. I can access 10.5.217.X traffic to the correct interface and all traffic on the 10.4.X.X traffic and 10.5.X.X on the appropriate interface.

  The problem appears when I try to access another network on the 10.5.217.X interface. The other network is 10.5.195.0. I add a static route to 10.5.195.0 to use the address of a default gateway of 10.5.217.1. This does not work because XP has chosen to use the 10.4.0.0 interface, even if I ping the 10.5.217.1 router directly. I try again and this time I specify the interface 10.5.217.X and now I can access the 10.5.195.0 network through the appropriate interface. This will work until the XP guest is restarted. After that, the XP customer returns to use interface 10.4.X.X for the 10.5.195.0 network and who doesn't.

  In ESXi, a reboot of the XP client did not cause the routing back to another interface, while I see this behavior in ESX.

  First of all, it's a bad network with overlap configuration.

  Put good metric for this route, so it would come first in the routing table.

  you use the subnet mask different than the one you used. According to the route table entry mask is 29

  Copy the static route statement and paste this what with 'no' in the global configuration and check the routing table.

• Static route ISA570W to Comcast gateway/modem

  In my view, that it is a question of static route.

  I want to be able to connect to the gateway/Modem Comcast (10.1.10.1) using any computer on my network. Currently, I am unable to do this, I am also unable to ping the unit of Comcast. Here's my setup.

  Comcast device (SMC8014)

  LAN IP: 10.1.10.1 (255.255.255.0)

  A single cable CAT5E for:

  LAN IP: 10.1.10.3 (255.255.255.0)

  For devices on my network to get an IP address from the device of the ISA, ISA is also the default gateway. I have logged on to the device of Comcast and all firewall rules and blocking are disabled.

  Here's a copy of my current routing table according to the ISA570:

  -Matthew-

  OK, a few possibilities here.

  1. Did you go through this process for the SMC8014 Bridge mode?
     • http://www.handymanhowto.com/2011/08/19/how-to-configure-a-Comcast-business-class-static-IP-address/
  2. I advise to use a different subnet on the LAN of the ISA to the 10.1.10.x interface.  The reason is that when you send a request from a subnet of 10.1.10.x behind the ISA to a subnet of 10.1.10.x, your PC and the ISA assumes that the device is on the same network and will not try to route.  Consider using the subnet of 192.168.75.x by default on ISA LAN interface.

  If you do not step 1 above, then I'm fairly certain that you will not be able to browse the internet at all.  If you can browse the internet, but just can't get the Comcast router 10.1.10.1, then chances are 1 step has already been completed.

• Adding static route to the ACS

  How can I add a static route to my device SE ACS?

  I try to get AAA works on a Cisco 871 is an end of distance of a vpn s2s ASA to 871. On the router, I use as the source for Ganymede interface vlan1.

  My ACS server is on the subnet for my ASA management, but the GBA to the Remote LAN road is via its default gateway and interface from the INSIDE of the SAA. I need to get the traffic of Ganymede ACS to return through the management interface of ASA.

  Thanks in advance.

  John,

  There is no way to set a static route in the GBA unit. The only network settings, you can set are the ip address/subnet, default gateway and dns servers.

• Static routing

  Hello

  I'm trying to set up a NSX environment using the static routes. As I am not a network expert, I need help here. Let me describe my environment:

  -NSX 6.2.1 is installed

  -DLR one is deployed and a logical switch is created. 172.16.10.0/24 is assigned to the logical switch and a few virtual machines are running.

  -One ESG is deployed. The GSS and the DLR are connected a logical switch in Transit and on the static route is added between the two.

  -The GSS was uplinked to the outside world via External-vDS and having 192.168.10.10 as IP uplink

  Now, the problem is that I can't reach the virtual computers in the VXLAN (172.16.10.0/24) from external computers.

  I have to add a static route on the device Physics (Cisco router) (route ip 172.16.10.0 255.255.255.0 192.168.10.10)?

  If it is not needed, what I have to do this work?

  I really appreciate your answers.

  Thank you

  You'll want to make sure that traffic destined to the networks behind the GSS is correctly routed through the physical network in the overlay.  One way to do would be to use a static route as you had mentioned to the physical router.  Once in place, the GSS would need a static route to send traffic for 172.16.10.0/24 network to the DLR.  The DLR would need a default route, which would point to the internal GSS interface, while the GSS would have a default route pointing to the physical router.
