[SwitchD-bgp-af-ipv6] peer 102::1 as-number 200

3.

Configure route reflector.

# Configure Switch C as a route reflector, and configure Switch B and Switch D as its clients.

[SwitchC-bgp-af-ipv6] peer 101::2 reflect-client

[SwitchC-bgp-af-ipv6] peer 102::2 reflect-client

Use the display bgp ipv6 routing-table command on Switch B and Switch D; both of them learned the
network 1::/64.

Configuring BFD for IPv6 BGP

Network requirements

As shown in

Figure 115

,

Configure OSPFv3 as the IGP in AS 200.

Establish two iBGP connections between Switch A and Switch C. When both links are working,
Switch C adopts the link Switch A<—>Switch B<—>Switch C to exchange packets with network

1200::0/64. Configure BFD over the link. Then if the link fails, BFD can quickly detect the failure

and notify it to IPv6 BGP. Then the link Switch A<—>Switch D<—>Switch C takes effect

immediately.
