   I am wanting to connect our two routers (A,B both in AS 16895) to two
   different ISPs (ISP-4323, ISP-16895) and had a few questions about
   making them talk to each other, and to the ISPs.

   They already have loopbacks and am not sure if I need ebgp-multihop or
   some other commands.

   Router A
   interface serial 0
     ip addr 192.168.1.1 255.255.255.252
     description to ISP-4323
   interface loopback 0
      ip addr 10.0.0.1
   router bgp 16895
      network 216.54.167.0 mask 255.255.255.0
      network 216.54.168.0 mask 255.255.255.0
      network 216.54.169.0 mask 255.255.255.0
      network 216.54.170.0 mask 255.255.255.0
      no sync
      neighbor 192.168.1.2 remote-as 4323
      neighbor 192.168.1.2 update-source loopback 0
      neighbor 10.0.0.11 remote-as 16895
      neighbor 10.0.0.11 update-source loopback0


   RouterB
   interface serial 0
     ip addr 172.16.1.1 255.255.255.252
     description to ISP-4323
   interface loopback 0
     ip addr 10.0.0.11 255.255.255.255
   router bgp 16895
      network 216.54.167.0 mask 255.255.255.0
      network 216.54.168.0 mask 255.255.255.0
      network 216.54.169.0 mask 255.255.255.0
      network 216.54.170.0 mask 255.255.255.0
      neighbor 172.16.1.2 remote-as 3847
      neighbor 172.16.1.2 update-source loopback 0
      neighbor 10.0.0.1 remote-as 16895
      neighbor 10.0.0.1 update-source loopback0
