Usage Information
At least one of the routes included in the aggregate address must be in the BGP routing table for the
congured aggregate to become active.
Do not add the as-set parameter to the aggregate if routes within the aggregate are constantly changing
as the aggregate will ap 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 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.
bgp always-compare-med
Allows you to enable comparison of the MULTI_EXIT_DISC (MED) attributes in the paths from dierent external ASs.
Syntax
bgp always-compare-med
To disable comparison of MED, use the no bgp always-compare-med command.
Defaults Disabled (that is, the software only compares MEDs from neighbors within the same AS).
