3Com MSR 50, MSR 30 manual Peer preferred-value IPv6 address family view, 1255

1255

By default, the system sets the next hop of routes advertised to an EBGP peer/peer group to the local router, but does not set for routes outgoing to an IBGP peer/peer group.

Examples # Set the next hop of routes advertised to EBGP peer group test to the router itself.

peer preferred-value (IPv6 address family view)

Syntax peer { ipv6-group-name ipv6-address } preferred-valuevalue

undo peer { ipv6-group-name ipv6-address } preferred-value

View IPv6 address family view

Parameters ipv6-group-name: Name of a peer group, a string of 1 to 47 characters.

ipv6-address: IPv6 address of a peer.

value: Preferred value, in the range 0 to 65535.

Description Use the peer preferred-valuecommand to assign a preferred value to routes received from a peer or peer group.

Use the undo peer preferred-valuecommand to restore the default.

By default, routes received from a peer or peer group have a preferred value of 0.

Routes learned from peers each have an initial preferred value. Among multiple routes to the same destination, the route with the biggest value is selected.

Note that:

If you both reference a routing policy and use the command peer

{ipv6-group-name ipv6-address } preferred-valuevalue to set a preferred value for routes from a peer, the routing policy sets a non-zero preferred value for routes matching it. Other routes not matching the routing policy uses 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 command. For information about using a routing policy to set a preferred value, refer to “peer group (IPv6 address family view)” on page 1251 and “peer route-policy (IPv6 address family view)” on page 1258 { import export } in this document and “apply preferred-value” on page 1194.

Examples # Configure the preferred value as 50 for routes from peer 1:2::3:4.
