C613-50100-01 REV C Command Reference for x930 Series 1159
AlliedWare Plus™ Operating System - Version 5.4.6-1.x
BGP AND BGP4+ COMMANDS
AGGREGATE
-ADDRESS
aggregate-address
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 neighbor
unsuppress-map 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
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:
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.
