20.4.2 Example of Basic BGP WAN Connectivity
This example includes a basic and very common BGP WAN connectivity scenario. The
local MSBR establishes a BGP adjacency with the ISP router and receives a default route
from it, allowing it full connectivity to the “Outside World”.
Usually in scenarios like this, the internal (LAN) network segment is allocated by the ISP
and allows it to be routed across the ISP network.

20.4.2.1 Configuration
MSBR# configure data
MSBR(conf-data)# router bgp AS-Number
MSBR(conf-router)# neighbor <ISP address> remote-as 55101
MSBR(conf-router)# address-family ipv6
MSBR(conf-router-af)# neighbor <ISP address> activate
20.4.2.2 Output
The following output shows the local parameters of the BGP process and the established
BGP adjacencies:
MSBR# show data ipv6 bgp summary

The following output shows that the router is learning a default route through the ISP BGP
peer:
MSBR# show data ipv6 route
