{attribute-map route-map-name] [suppress-map route-map-name]
Parameters
• address/mask — Enter the IP address and mask.
• as-set — (Optional) Generates AS set-path information.
• summary-only — (Optional) Filters more specic routes from updates.
• advertise-map map-name — (Optional) Enter the map name to advertise.
• attribute-map route-map-name — (Optional) Enter the route-map name to set aggregate attributes.
• suppress-map route-map-name — (Optional) Enter the route-map name to conditionally lters specic

Default None
Command Mode ROUTER-BGPv4-AF
Usage Information At least one of the routes included in the aggregate address must be in the BGP routing table for the congured
aggregate to become active. If routes within the aggregate are constantly changing, do not add the as-set
parameter to the aggregate because the aggregate aps to track changes in the AS_PATH. The no version of this
command disables the aggregate-address conguration.
Example
OS10(conf-router-bgpv4-af)# aggregate-address 6.1.0.0/16 summary-only
Supported Releases 10.3.0E or later
allowas-in
Congures the number of times the local AS number can appear in the BGP AS_PATH path attribute before the switch rejects the route.
Syntax
allowas-in as-number
Parameters as-number—Enter the number of occurrences for a local AS number, from 1 to 10.
Default Disabled
Command Mode ROUTER-BPG-NEIGHBOR-AF
Usage Information Use this command to enable the BGP speaker to accept a route with the local AS number in updates received from
a peer for the specied number of times. The no version of this command resets the value to the default.
