Sample BGP network

Cisco Packet Tracer - BGP sample network

WAN1 router configuration  :

A simple eBGP peering with ISP1 router is configured in the WAN1 router.

interface Serial0/0/0
ip address 156.12.1.6 255.255.255.252
!
router bgp 65000
bgp log-neighbor-changes
no synchronization
neighbor 156.12.1.5 remote-as 10000

 

ISP1 router configuration :

Several loopback interfaces are configured in ISP1 router to simulate connected networks whose are advertised to WAN1 router through the BGP peering.

interface Loopback0
ip address 156.100.1.1 255.255.255.0
!
interface Loopback1
ip address 156.100.2.1 255.255.255.0
