group must have been created.
ip-address: Specifies a peer by its IP address. The peer must have been created.

Usage guidelines
If multiple routes that have the same destination are learned from different peers, you can specify
different preferred values for the routes as needed to control BGP path selection. The one with the
greatest preferred value is selected as the optimal route to the destination.
The preferred value is used for route selection on the local router and is not advertised to the peer. It has
only local significance.
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 is not set in the routing policy or no
routing policy is configured, the peer preferred-value command applies.
