Hi everyone,

I have a routing question which I don't know how to solve. I have two routers. Both are connected to my ISP and get a dynamic IP. Both are also connected to a local VLAN. I'd like to use the local VLAN for any traffic in between the two and the ISP for everything else. Basically, it should be like:

  # Router A
  1.2.3.x (DHCP)
  10.0.0.1/30
  10.0.1.1/24

  # Router B
  2.3.4.x (DHCP)
  10.0.0.2/30
  10.0.2.1/24

  # Network A: 10.0.1.0/24
  route 0.0.0.0/0 via 10.0.0.1
  route 2.3.4.x/32 via 10.0.0.2

  # Network B: 10.0.2.0/24
  route 0.0.0.0/0 via 10.0.0.2
  route 1.2.3.x/32 via 10.0.0.1

I've tried doing this with BGP with a config like this (on Router A, by example):

  AS 65001
  router-id 10.0.0.1
  network inet connected

  neighbor 10.0.0.2 {
          remote-as 65002
  }

The problem here is that a computer in Network A will now try to use Router B to connect to IP-address 2.3.4.5, whereas I want it to use Router A.

I'd appreciate if anyone could lead me in the right direction here. The reason why I'm doing is: I want to keep two networks separate, letting them browse the Internet with different IP addresses, but use the immediate link between the local routers for better performance.

Kind regards,
John Longe
