BGP GR configuration example
Network requirements
As shown in Figure 74, all switches run BGP. EBGP runs between Switch A and Switch B. IBGP runs
between Switch B and Switch C.
Enable GR capability for BGP so that the communication between Switch A and Switch C is not
affected when an active/standby switchover occurs on Switch B.

Configuration procedure
1. Configure Switch A:
# Configure IP addresses for interfaces. (Details not shown.)
# Configure the EBGP connection.
<SwitchA> system-view
[SwitchA] bgp 65008
[SwitchA-bgp-default] router-id 1.1.1.1
[SwitchA-bgp-default] peer 200.1.1.1 as-number 65009
# Enable GR capability for BGP.
[SwitchA-bgp-default] graceful-restart
# Inject network 8.0.0.0/8 to the BGP routing table.
[SwitchA-bgp-default] address-family ipv4
[SwitchA-bgp-default-ipv4] network 8.0.0.0
# Enable Switch A to exchange IPv4 unicast routing information with Switch B.
[SwitchA-bgp-default-ipv4] peer 200.1.1.1 enable
2. Configure Switch B:
# Configure IP addresses for interfaces. (Details not shown.)
# Configure the EBGP connection.
