BGP Lab 19 Injecting IPv6 prefixes into BGP (CCNP Level)
Download Lab: GNS3
Previous Next
Image requirements:
Cisco IOSv (vios-adventerprisek9-m.vmdk.SPA.156-2.T)
Introduction:
After all BGP neighborship configurations have been completed it is time to advertise IPv6 prefixes. Each ISP router will propagate its /48 prefix. This prefix is the static route pointing to null0. As for autonomous system 250, routers, R1 and R2 will redistribute their loopback1 prefixes into iBGP.
Lab Tasks:
1. Starting with ISP4 then in reverse order, on the rest of ISPs' routers, using the BGP network command advertise the /48 prefix.
2. Redistribute R1's only connected prefixes of loopback1 interfaces into iBGP.
3. Redistribute R2's only connected prefixes of loopback1 interfaces into iBGP.
4. Verify that all routers in the topology received prefixes of all existing autonomous systems.
5. Save running-config
Configuration example:
!
ISP4#show ipv6 route static
S 2001:DB8:104::/48 [1/0]
via Null0, directly connected
!
ISP4#conf t
ISP4(config)#router bgp 104
ISP4(config-router)#address-family ipv6
ISP4(config-router-af)#network 2001:DB8:104::/48
ISP4(config-router-af)#end
!
Verify the local BGP table:
!
ISP4# show bgp ivp6 unicast
!
!
R1(config)#route-map LOOPBACK1 permit 10
R1(config-route-map)#match interface loopback 1
R1(config-route-map)#exit
!
R1(config)#router bgp 250
R1(config-router)#address-family ipv6
R1(config-router-af)#redistribute connected route-map LOOPBACK1
R1(config-router)# end
!
Verify the local BGP table:
!
R1# show bgp ivp6 unicast
