You can also use the
apply preferred-value
command in a routing policy to configure the preferred value
for BGP routes. If both the
peer preferred-value
and
apply preferred-value
commands are configured,
the
apply preferred-value
command applies. If the preferred value set by the
apply preferred-value
command is 0 or no routing policy is configured, the
peer preferred-value
command applies.
Examples
# In BGP IPv4 unicast instance view, specify the preferred value as 50 for routes from peer 1.1.1.1.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv4-family unicast
[Sysname-bgp-ipv4] peer 1.1.1.1 preferred-value 50
# In BGP-VPN IPv6 unicast instance view, specify the preferred value as 50 for routes from peer 1::1.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] ipv6-family unicast
[Sysname-bgp-ipv6-vpn1] peer 1::1 preferred-value 50
