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.
Do not add the
as-set
parameter to the aggregate if routes within the aggregate are
constantly changing as 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 still appears 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.
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.
bgp always-compare-med
Allows you to enable comparison of the MULTI_EXIT_DISC (MED) attributes in the paths from different external ASs.
C-Series, E-Series
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).
