The ip-addr parameter specifies a neighbor IP address for the individual neighbor you are
configuring.

activate allows exchange of routes in the current family mode.

advertisement-interval seconds configures an interval in seconds over which the specified
neighbor will hold all route updates before sending them. At the expiration of the timer, the routes
are sent as a batch. The default value for this parameter is zero. Acceptable values are 0 to 600
seconds.

allowas-in num disables the AS_PATH check function for routes learned from a specified location.
BGP4 usually rejects routes that contain an AS number within an AS_PATH attribute to prevent
routing loops. In an MPLS or VPN hub and spoke topology this can prevent legitimate routes from
being accepted. The allowas-in option stops this blockage. num specifies the number of
occurrences of the AS number.

capability as4 [enable | disable] enables the capability of processing AS4s. The optional keywords
enable | disable specify whether the feature should be changed from its current state.

default-originate [route-map map-name] configures the device to send the default route 0.0.0.0 to
the neighbor. If you use the route-map map-name parameter, the route map injects the default
route conditionally, based on the match conditions in the route map.

description string specifies a name for the neighbor. You can enter an alphanumeric text string up
to 80 characters long.

distribute-list in | out num,num,... specifies a distribute list to be applied to updates to or from the
specified neighbor. The in | out keywords specify whether the list is applied on updates received
from the neighbor, or sent to the neighbor. The num,num,... parameter specifies the list of
address-list filters. The device applies the filters in the order in which you list them and stops
applying the filters in the distribute list when a match is found.

To use an IP ACL instead of a distribute list, you can specify distribute-list acl-num in | out . In this
case, acl-num is an IP ACL.
