3. Let’s add in the BGP. It too uses an autonomous system number. Let’s use 100
for the ISP and 200 for our serial 1 interface.
ISP(config)# router bgp 100
ISP(config-router)#no synchronization
ISP(config-router)#network 193.168.1.0
ISP(config-router)#network 210.1.1.0
ISP(config-router)#neighbor 210.1.1.2 remote-as 200
cult(config)#router bgp 200
cult(config-router)#no synchronization
cult(config-router)#network 210.1.1.0
cult(config-router)#redistribute eigrp 13
cult(config-router)#neighbor 210.1.1.1 remote-as 100
4. Next we need to redistribute our routing protocols:
cult(config)#router eigrp 13
cult(config-router)#redistribute bgp 200
cult(config-router)#passive-interface Serial0/1
cult(config-router)#default-metric 1000 100 250 100 1500
cult(config)#router bgp 200
cult(config-router)#redistribute eigrp 13
5. Now let’s see our ip routes:
ISP#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default
U - per-user static route, o - ODR
Gateway of last resort is not set
C 193.168.1.0/24 is directly connected, Loopback0
B 192.168.1.0/24 [20/0] via 210.1.1.2, 00:09:52
C 210.1.1.0/24 is directly connected, Serial0/0
B 192.168.2.0/24 [20/0] via 210.1.1.2, 00:09:52
