Allied Telesis VERSION 5.4.3-2.6, BGP4 Configure terminal, Aggregate-address 192.0.0.0/8 as-set

BGP and BGP4+ Commands

The as-setparameter controls the AS-path attribute that is advertised with the aggregate route. If the switch has learnt multiple routes that are within the range of the aggregate address/mask, and the AS-paths associated with those routes contain different sets of AS-numbers, then it is not possible to create a single AS-path that accurately represents the AS-paths of all those component routes. In this case, the switch will, by default, advertise a NULL AS-path with the aggregate.

Usage [BGP4+] 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)#address-family ipv6

awplus(config-router-af)# aggregate-address 2001:0db8::/64

summary-only

then the switch will advertise the prefix 2001:0db8::/64, but no component routes like 2001:0db8:010d::1/128

Examples [BGP]

awplus#	configure terminal
awplus(config)#	router bgp 100
awplus(config-router)#	aggregate-address 192.0.0.0/8 as-set
	summary-only
awplus#	configure terminal
awplus(config)#	router bgp 100
awplus(config-router)#	no aggregate-address 192.0.0.0/8 as-set
	summary-only
