Configuring a preferred value for routes from a peer/peer
group
Follow these steps to configure a preferred value for routes from a peer/peer group:
To do… Use the command… Remarks
Enter system view
system-view —
Enter BGP view
bgp as-number —
Enter IPv6 MBGP address family
view
ipv6-family multicast —
Specify a preferred value for
routes received from the IPv6
MBGP peer/peer group
peer { ipv6-group-name | ipv6-
address } preferred-value value
Optional
The preferred value defaults to 0.
CAUTION:
If you both reference a routing policy and use the command peer {
ipv6-group-name | ipv6-address
}
preferred-value
value
to set a preferred value for routes from a peer/peer group, the routing policy
sets the specified preferred value for routes matching it. Other routes that do not match the routing
policy use the value set with the command. If the preferred value in the routing policy is zero, the routes
matching it will also use the value set with the peer {
ipv6-group-name | ipv6-address
} preferred-
alue
value
command. To use a routing policy to set a preferred value, use the peer {
ipv6-group-nam
|
ipv6-address
} route-policy
route-policy-name
{ import | export } command and the apply
preferred-value
preferred-value
command. For more information about the commands, see the
