Usage Information At least one of the routes included in the aggregate address must be in the BGP routing table for the configured aggregate to become active. If routes within the aggregate are constantly changing, do not add the as-set parameter to the aggregate as the aggregate flaps 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 also true: routes meeting the permit clause are suppressed. If the route is injected via the network command, that route still appears in the routing table if the summaryonly 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. In the show ip bgp command, aggregates contain an 'a' in the first column and routes suppressed by the aggregate contain an 's' in the first column. When an aggregate address is denied using a peer's outbound route-map, individual routes suppressed by the aggregate address are advertised to that peer. The attribute-map corresponding to an aggregate address is applied during the outbound update creation time; the value set in that attribute-map will not be shown in the output of the show ip bgp aggregate route command. bgp add-path Allow the advertisement of multiple paths for the same address prefix without the new paths replacing any previous ones. Syntax Parameters bgp add-path [send | receive | both | enable] path-count send receive both enable path-count Enter the keyword send to indicate that the system sends multiple paths to peers. Enter the keyword receive to indicate that the system accepts multiple paths from peers. Enter the keyword both to indicate that the system sends and accepts multiple paths from peers. Enter the keyword enable to enable add-path support support for the node. Enter the number paths supported. The range is from 2 to 64. Defaults Disabled Border Gateway Protocol 331
