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
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)#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
