BGP Peering

Consider that IP connectivity between ISPs edge routers and Our Core router is already set up and working properly. So we can start to establish BGP peering to both ISPs.


ISP1:

vtysh
configure terminal
  router bgp 10
  bgp router-id 192.168.1.1
    no synchronization
    bgp log-neighbor-changes
    ! address-family ipv4 unicast 
    network 10.100.100.0/24
    network 10.100.200.0/24
    neighbor 192.168.3.2 remote-as 20
    neighbor 192.168.1.2 remote-as 30
    neighbor 192.168.3.2 password $AP7i1
    neighbor 192.168.1.2 password $AP7i1
  end

ISP2:


vtysh
configure terminal
  router bgp 20
  bgp router-id 192.168.2.1
    no synchronization
    bgp log-neighbor-changes
    network 10.10.10.0/24
    network 10.10.20.0/24
    neighbor 192.168.3.1 remote-as 10
    neighbor 192.168.2.2 remote-as 30
    neighbor 192.168.3.1 password $AP7i1
    neighbor 192.168.2.2 password $AP7i1
  end

ISP3:

enable
configure terminal
  router bgp 30
  bgp router-id 192.168.1.2
    no synchronization
    bgp log-neighbor-changes
    network 10.1.1.0/24
    network 10.1.2.0/24
    neighbor 192.168.1.1 remote-as 10
    neighbor 192.168.2.1 remote-as 20
    neighbor 192.168.1.1 password $AP7i1
    neighbor 192.168.2.1 password $AP7i1
  end

Cek
