Allied Telesis VERSION 5.4.3-2.6 manual Aggregate-address BGP and BGP4+, Summary-only, As-set

BGP and BGP4+ Commands

aggregate-address (BGP and BGP4+)

This command adds an aggregate route that can be advertised to BGP or BGP4+ neighbors. This command creates an aggregate entry in the BGP or BGP4+ routing table if the switch learns, by any means, any routes that are within the range configured by the aggregate address/mask.

When this command is used with the summary-onlyoption, the more-specific routes of the aggregate are suppressed to all neighbors. Use the neighbor unsuppress-map (BGP and BGP4+) command instead to selectively leak more-specific routes to a particular neighbor.

The no variant of this command removes the aggregate configured by the aggregate- address command.

Syntax [BGP]	aggregate-address <ip-addr/m> {summary-onlyas-set}
	no aggregate-address <ip-addr/m> {summary-onlyas-set}
Syntax [BGP4+]	aggregate-address <ipv6-addr/prefix-length>{summary-onlyas-set}
	no aggregate-address <ipv6-addr/prefix-length>{summary-onlyas-set}
	Parameter	Description
	<ip-addr/m>	Specifies the aggregate IPv4 address and mask.
	<ipv6-addr/	Specifies the aggregate IPv6 address. The IPv6 address uses
	prefix-length>	the format X:X::X:X/Prefix-Length. The prefix-length is usually
		set between 0 and 64.
	summary-only	Filters more specific routes from updates. Only the aggregate
		address/mask will be advertised, and none of the component
		addresses that fall within the range of the aggregate address/
		mask.
	as-set	Generates AS set path information. The AS-path advertised
		with the aggregate is an unordered list of all the AS-numbers
		that appear in any of the AS-paths of the component routes,
		with each AS-number appearing just once in the list.

Mode [BGP]	Router Configuration or IPv4 Address Family Configuration for a VRF instance
Mode [BGP4+]	IPv6 Address Family Configuration
Usage [BGP]	If the summary-onlyparameter is specified, then only the aggregate address/mask will
	be advertised, and none of the component addresses that fall within the range of the
	aggregate address/mask. For example, if you configure:
	awplus# configure terminal
	awplus(config)# router bgp 100
	awplus(config-router)# aggregate-address 172.0.0.0/8 summary-only
	then the switch will advertise the prefix 172.0.0.0/8, but no component routes like
	172.10.0.0/16
