www.dell.com | support.dell.com aggregate-address c et s Summarize a range of prefixes to minimize the number of entries in the routing table. Syntax aggregate-address ip-address mask [advertise-map map-name] [as-set] [attribute-map map-name] [summary-only] [suppress-map map-name] Parameters ip-address mask advertise-map map-name as-set attribute-map map-name summary-only suppress-map map-name Enter the IP address and mask of the route to be the aggregate address. Enter the IP address in dotted decimal format (A.B.C.D) and mask in / prefix format (/x). (OPTIONAL) Enter the keywords advertise-map followed by the name of a configured route map to set filters for advertising an aggregate route. (OPTIONAL) Enter the keyword as-set to generate path attribute information and include it in the aggregate. AS_SET includes AS_PATH and community information from the routes included in the aggregated route. (OPTIONAL) Enter the keywords attribute-map followed by the name of a configured route map to modify attributes of the aggregate, excluding AS_PATH and NEXT_HOP attributes. (OPTIONAL) Enter the keyword summary-only to advertise only the aggregate address. Specific routes will not be advertised. (OPTIONAL) Enter the keywords suppress-map followed by the name of a configured route map to identify which more-specific routes in the aggregate are suppressed. Defaults Not configured. Command Modes ROUTER BGP Address Family (conf-router_bgp_af) Usage At least one of the routes included in the aggregate address must be in the BGP routing table for the Information configured aggregate to become active. Do not add the as-set parameter to the aggregate. If routes within the aggregate are constantly changing, the aggregate will flap to keep track of the changes in the AS_PATH. In route maps used in the suppress-map parameter, routes meeting the deny clause are not suppress; in other words, they are allowed. The opposite is true: routes meeting the permit clause are suppressed. If the route is injected via the network command, that route will still appear in the routing table if the summary-only parameter is configured in the aggregate-address command. The summary-only parameter suppresses all advertisements. If you want to suppress advertisements to only specific neighbors, use the neighbor distribute-list command.
