NETGEAR 8800 Chassis Switch CLI Manual ip address/mask length all Specifies an IP network address and netmask length. Specifies all aggregated routes. Default If no address family is specified, IPv4 unicast is the default. Usage Guidelines Route aggregation is the process of combining the characteristics of several routes so that they are advertised as a single route. Aggregation reduces the amount of information that a BGP speaker must store and exchange with other BGP speakers. Reducing the information that is stored and exchanged also reduces the size of the routing table. Example The following command deletes a BGP aggregate route: configure bgp delete aggregate-address 192.1.1.4/30 configure bgp delete confederation-peer sub-AS-number configure bgp delete confederation-peer sub-AS-number Description Specifies a sub-AS that should be deleted from a confederation. Syntax Description sub-AS-number Specifies a sub-AS. Default N/A. Usage Guidelines BGP requires that networks use a fully-meshed router configuration. This requirement does not scale well, especially when BGP is used as an interior gateway protocol. One way to reduce the size of a fully-meshed AS is to divide the AS into multiple sub-autonomous systems and group them into a routing confederation. Within the confederation, each sub-AS must be fully-meshed. The confederation is advertised to other networks as a single AS. Example The following command deletes a sub-AS from a confederation using the ASPLAIN 4-byte AS number format: Chapter 25. BGP Commands | 1083
