Bfd For Ipv6 Bgp Configuration Example - HP HPE FlexNetwork 7500 series Configuration Manual

BFD for IPv6 BGP configuration example

Network requirements
As shown in
•
Establish two IBGP connections between Switch A and Switch C. When both paths operate
correctly, Switch C uses the path Switch A<—>Switch B<—>Switch C to exchange packets
with network 1200::0/64.
•
Configure BFD over the path. When the path fails, BFD can quickly detect the failure and notify
it to IPv6 BGP. Then, the path Switch A<—>Switch D<—>Switch C takes effect immediately.

Configuration procedure
1. Configure IPv6 addresses for interfaces. (Details not shown.)
2. Configure OSPFv3 so that Switch A and Switch C can reach each other. (Details not shown.)
3. Configure IPv6 BGP on Switch A:
# Establish two IBGP connections to Switch C.
<SwitchA> system-view
[SwitchA] bgp 200
[SwitchA-bgp-default] router-id 1.1.1.1
[SwitchA-bgp-default] peer 3001::3 as-number 200
[SwitchA-bgp-default] peer 2001::3 as-number 200
[SwitchA-bgp-default] address-family ipv6
[SwitchA-bgp-default-ipv6] peer 3001::3 enable
Figure 85, configure OSPFv3 as the IGP in AS 200.
