Configuring a preferred value for routes from a peer or a peer
group
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 or a peer group, the routing policy
sets the specified preferred value for routes that match it. Other routes that do not match the routing policy
use the value set through the command. If the preferred value in the routing policy is 0, the routes that
match it will also use the value set through the
peer
{
ipv6-group-name
|
ipv6-address
}
preferred-value
value
command. To learn how to use a routing policy to set a preferred value, see the
