Peer Public-As-Only (Mbgp Family View) - 3Com S7906E Command Reference Manual

Default Level
2: System level
Parameters
group-name: Name of an IPv4 MBGP peer group, a string of 1 to 47 characters.
ip-address: IP address of an IPv4 MBGP peer.
value: Preferred value, in the range 0 to 65535.
Description
Use the peer preferred-value command to specify a preferred value for routes received from a peer or
peer group.
Use the undo peer preferred-value command to restore the default value.
The default preferred value is 0.
Routes learned from a peer have an initial preferred value. Among multiple routes that have the same
destination/mask and are learned from different peers, the one with the greatest preferred value is
selected as the route to the destination.
Note that:
If you both reference a route policy and use the peer { group-name | ip-address } preferred-value value
command to set a preferred value for routes from a peer/peer group, the route policy sets a specified
non-zero preferred value for routes matching it. Other routes not matching the route policy uses the
value set with the peer preferred-value command. If the preferred value specified in the route policy is
zero, the routes matching it will also use the value set with the command.
For information about using a route policy to set a preferred value, refer to the command peer
{ group-name | ip-address } route-policy route-policy-name { export | import } in this document, and
the command apply preferred-value preferred-value in Route policy Commands of the IP Routing
Volume.
