Specifies the autonomous system number of the external peer group.

Enter an integer between 1 and 65535.

aspath-prepend-count <1-25 | default>

Specifies the number of times this router adds to the autonomous system path on external BGP sessions.

description text

You can enter a brief text description of the group.

local-address <IP Address> {off | on}

Specifies the address used on the local end of the TCP connection with the peer group.

The local address must be on an interface that is shared with the peer or with the peer's gateway when the gateway parameter is used.

outdelay {<0-65535> | off}

Specifies the amount of time in seconds that a route must be present in the routing database before it is redistributed to BGP.

The configured value applies to all peers configured in this group.

This feature dampens route fluctuation.

The value zero (0) disables this feature.
