Bfd For Bgp Configuration Example - HP 6125XLG Configuration Manual

[SwitchB-bgp-ipv4] network 9.1.1.0 24
# Enable Switch B to exchange IPv4 unicast routing information with Switch A and Switch C.
[SwitchB-bgp-ipv4] peer 200.1.1.2 enable
[SwitchB-bgp-ipv4] peer 9.1.1.2 enable
3. Configure Switch C:
# Configure IP addresses for interfaces. (Details not shown.)
# Configure the IBGP connection.
<SwitchC> system-view
[SwitchC] bgp 65009
[SwitchC-bgp] router-id 3.3.3.3
[SwitchC-bgp] peer 9.1.1.1 as-number 65009
# Enable GR capability for BGP.
[SwitchC-bgp] graceful-restart
# Enable Switch C to exchange IPv4 unicast routing information with Switch B.
[SwitchC-bgp-ipv4] peer 9.1.1.1 enable
Verifying the configuration
Ping Switch C on Switch A. Meanwhile, perform an active/standby switchover on Switch B. The ping
operation is successful during the whole switchover process.

BFD for BGP configuration example

Network requirements
As shown in
Configure OSPF as the IGP in AS 200.
•
• Establish two IBGP connections between Switch A and Switch C. When both paths are working,
Switch C adopts the path Switch A<—>Switch B<—>Switch C to exchange packets with network
1.1.1.0/24. Configure BFD over the path. If the path fails, BFD can quickly detect the failure and
notify it to BGP. Then the path Switch A<—>Switch D<—>Switch C takes effect immediately.
