BGP configuration commands The term "router" in this chapter refers to both routers and Layer 3 switches. For more information about routing policy configuration commands in this document, see "Routing policy configuration commands." aggregate Syntax aggregate ip-address { mask | mask-length } [ as-set | attribute-policy route-policy-name | detail-suppressed | origin-policy route-policy-name | suppress-policy route-policy-name ] * View undo aggregate ip-address { mask | mask-length } BGP view, BGP-VPN instance view Default level 2: System level Parameters ip-address: Summary address. mask: Summary route mask, in dotted decimal notation. mask-length: Length of summary route mask, in the range of 0 to 32. as-set: Creates a summary with AS set. attribute-policy route-policy-name: Sets the attributes of the summary route according to the routing policy The routing policy name is a case-sensitive string of 1 to 63 characters. detail-suppressed: Only advertises the summary route. suppress-policy route-policy-name: Suppresses specific routes defined in the routing policy. The routing policy name is a case-sensitive string of 1 to 63 characters. origin-policy route-policy-name: References the routing policy to specify routes for summarization. The routing policy name is a case-sensitive string of 1 to 63 characters. Table 28 Functions of the keywords Keywords as-set detail-suppressed Function Used to create a summary route, whose AS path contains the AS path information of summarized routes. Use this keyword carefully when many AS paths need to be summarized, because the frequent changes of these specific routes may lead to route oscillation. This keyword does not suppress the summary route, but it suppresses the advertisement of all the more specific routes. To summarize only some specific routes, use the peer filter-policy command. 126
