Bfd For Bgp Configuration Example - HP 6125G Configuration Manual

# Inject network 8.0.0.0/8 to the BGP routing table.
[SwitchA-bgp] network 8.0.0.0
# Enable GR capability for BGP.
[SwitchA-bgp] graceful-restart
Configure Switch B:
2.
# Configure IP addresses for interfaces. (Details not shown.)
# Configure the EBGP connection.
<SwitchB> system-view
[SwitchB] bgp 65009
[SwitchB-bgp] router-id 2.2.2.2
[SwitchB-bgp] peer 200.1.1.2 as-number 65008
# Configure the IBGP connection.
[SwitchB-bgp] peer 9.1.1.2 as-number 65009
# Inject networks 200.1.1.0/24 and 9.1.1.0/24 to the BGP routing table.
[SwitchB-bgp] network 200.1.1.0 24
[SwitchB-bgp] network 9.1.1.0 24
# Enable GR capability for BGP.
[SwitchB-bgp] graceful-restart
Configure Switch C:
3.
# 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
Verify the configuration:
4.
Ping Switch C on Switch A. Meanwhile, perform a master/slave 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 links are working,
•
Switch C adopts the link Switch A<—>Switch B<—>Switch C to exchange packets with network
1.1.1.0/24. Configure BFD over the link. Then if the link fails, BFD can quickly detect the failure and
notify it to BGP. Then the link Switch A<—>Switch D<—>Switch C takes effect immediately.
