IPv6 BGP FRR configuration example

Network requirements
As shown in
Figure 76 Network diagram
Router A
AS 100
Configuration procedure
1. Configure IPv6 addresses for interfaces. (Details not shown.)
2. Configure OSPFv3 in AS 200 to ensure connectivity among Router B, Router C, and Router D.
(Details not shown.)
3. Configure BGP connections:
# Configure Router A to establish EBGP sessions with Router B and Router C, and advertise
network 1::/64.
