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:
enable configure terminal router bgp 10 bgp router-id 192.168.1.1 ! address-family ipv4 unicast network 10.100.100.0 mask 255.255.255.0 network 10.100.200.0 mask 255.255.255.0 neighbor 192.168.3.2 remote-as 20 neighbor 192.168.1.2 remote-as 30 neighbor 192.168.3.2 activate neighbor 192.168.1.2 activate ! neighbor 192.168.3.2 default-originate ! neighbor 192.168.1.2 default-originate end
ISP2:
enable configure terminal router bgp 20 bgp router-id 192.168.2.1 ! address-family ipv4 unicast network 10.10.10.0 mask 255.255.255.0 network 10.10.20.0 mask 255.255.255.0 neighbor 192.168.3.1 remote-as 10 neighbor 192.168.2.2 remote-as 30 neighbor 192.168.3.1 activate neighbor 192.168.2.2 activate end
ISP3:
enable configure terminal router bgp 30 bgp router-id 192.168.1.2 ! address-family ipv4 unicast network 10.1.1.0 mask 255.255.255.0 network 10.1.2.0 mask 255.255.255.0 neighbor 192.168.1.1 remote-as 10 neighbor 192.168.2.1 remote-as 20 neighbor 192.168.1.1 activate neighbor 192.168.2.1 activate end
Cek
