name] {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 specific 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 filter
specific routes from updates.
Default None
Command Mode ROUTER-BGPv4-AF
Usage
Information
At least one of the routes that is included in the aggregate address must be in the BGP routing table for
the configured 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 flaps to track changes in the
AS_PATH. The no version of this command disables the aggregate-address configuration.
Example
OS10(conf-router-bgpv4-af)# aggregate-address 6.1.0.0/16 summary-only
Supported
Releases
10.3.0E or later
allowas-in
Configures 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 specified number of times. The no version of this command resets the value
to the default.

OS10(config-router-neighbor)# address-family ipv4 unicast

Example (IPv6)
OS10(conf-router-template)# address-family ipv6 unicast
OS10(conf-router-bgp-template-af)# allowas-in 5
Example (l2vpn)
