Overview
This command adds an aggregate route that can be advertised to BGP or BGP4+
neighbors. This command creates an aggregate entry in the BGP or BGP4+ routing
table if the device learns, by any means, any routes that are within the range
configured by the aggregate address/mask.
When this command is used with the
summary-only
option, the more-specific
routes of the aggregate are suppressed to all neighbors. Use the
command instead to selectively leak more-specific routes to a
particular neighbor.
The
no
variant of this command removes the aggregate configured by the
aggregate-address
command.

Usage [BGP]
If the
summary-only
parameter is specified, then only the aggregate
address/mask will be advertised, and none of the component addresses that fall
within the range of the aggregate address/mask. For example, if you configure:
Parameter
Description
<ip-addr/m>
Specifies the aggregate IPv4 address and mask.
<ipv6-addr/
prefix-length>
Specifies the aggregate IPv6 address. The IPv6 address uses
the format X:X::X:X/Prefix-Length. The prefix-length is usually
set between 0 and 64.
summary-only
Filters more specific routes from updates. Only the aggregate
address/mask will be advertised, and none of the component
addresses that fall within the range of the aggregate address/
mask.
as-set
Generates AS set path information. The AS-path advertised
with the aggregate is an unordered list of all the AS-numbers
that appear in any of the AS-paths of the component routes,
with each AS-number appearing just once in the list.
