Dell Force10 Z9000 Configuration Manual page 216

When you enable a route reflector, FTOS automatically enables route reflection to all clients. To disable
route reflection between all clients in this reflector, use the
CONFIGURATION ROUTER BGP mode. All clients should be fully meshed before you disable route
reflection.
Aggregate routes
FTOS provides multiple ways to aggregate routes in the BGP routing table. At least one specific route of
the aggregate must be in the routing table for the configured aggregate to become active.
Use the following command in the CONFIGURATION ROUTER BGP mode to aggregate routes.
Command Syntax
aggregate-address ip-address
mask [ advertise-map map-name]
[ as-set ] [ attribute-map map-name]
[ summary-only ] [ suppress-map
map-name]
AS_SET includes AS_PATH and community information from the routes included in the aggregated route.
In the
show ip bgp
aggregate contain an 's' in the first column.

Purpose
Assign the IP address and mask of the prefix to be
aggregated.
Optional parameters are:
advertise-map map-name:
•
advertising an aggregate route
• as-set : generate path attribute information and
include it in the aggregate.
attribute-map map-name: modify
•
the aggregate, except for the AS_PATH and
NEXT_HOP attributes
summary-only:
