Users Guide

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 using the network command, that route still appears in the routing table if you congure

the summary-only parameter in the aggregate-address command.

The summary-only parameter suppresses all advertisements. If you want to suppress advertisements to only

specic neighbors, use the neighbor distribute-list command.

In the show ip bgp ipv6 unicast command, aggregates contain an ‘a’ in the rst column and routes

suppressed by the aggregate contain an ‘s’ in the rst column.

Allows you to enable comparison of the MULTI_EXIT_DISC (MED) attributes in the paths from dierent external ASs.
