[Xorp-users] BGP not advertising our route?

[Ethan Sommer]

We recently noticed that our BGP setup isn't working correctly. We have
two ip connections, one to I2 (which uses BGP) and the other for
commodity Internet (which uses a default route and our ISP presumably
advertises our route.)

We receive all 11000+ I2 routes, and send things out over our I2
connection, but we must not be advertising our route properly because
starting when we started using xorp (rather than quagga) people have
been routing back to us over I1. I assuming I'm doing something wrong in
the BGP section of the config, but I don't know where to start to find
the problem.

Our IP

Our BGP config is as follows: (our ip range is 138.236.0.0/16)
bgp {
  bgp-id: 192.42.152.93
  local-as: 17234
  peer 192.42.152.94 {
    local-ip: 192.42.152.93
    as: 57
    next-hop: 192.42.152.94 /* is this necesary? */
  }
   peer 216.114.193.145 {
      local-ip: 216.114.193.146
      as: 12112
      next-hop: 216.114.193.145 /* is this necesary? */
   }
}

We'd appreciate any tips you have, thanks,

Ethan
