Usually, BGP uses the optimal source interface to forward route updates. However, for

updates to be forwarded in case the interface experiences a failure, you can configure

to use the Loopback interface for forwarding route updates.

Example

# Specify to use loopback0 as the source interface for route updates.

[3Com -bgp] peer test connect-interface loopback 0

5.1.43 peer default-route-advertise

Syntax

peer group-name default-route-advertise

undo peer group-name default-route-advertise

View

BGP view

Parameter

group-name: Specifies the name of the peer group.

Description

Use the peer default-route-advertise command to redistribute a default route to a

peer group.

Use the undo peer default-route-advertise command to cancel the existing

configuration.

By default, no default route is redistributed to a peer group.

For this command, no default route is required in the routing table. A default route is

sent unconditionally to a peer with the next hop being itself.

Example

# Redistribute a default route to peer group "test".

[3Com -bgp] peer test as-number 100

[3Com -bgp] peer test default-route-advertise
