aggregate-address (BGP and BGP4+)
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 switch 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 neighbor unsuppress-map (BGP
and BGP4+) 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.
Syntax [BGP] aggregate-address <ip-addr/m> {summary-only|as-set}
no aggregate-address <ip-addr/m> {summary-only|as-set}
Syntax [BGP4+] aggregate-address <ipv6-addr/prefix-length> {summary-only|as-set}
no aggregate-address <ipv6-addr/prefix-length> {summary-only|as-set}
Mode [BGP] Router Configuration or IPv4 Address Family Configuration for a VRF instance
Mode [BGP4+] IPv6 Address Family Configuration
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:
then the switch will advertise the prefix 172.0.0.0/8, but no component routes like
172.10.0.0/16
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.
