Summarize a range of prefixes to minimize the number of entries in the routing table.
C-Series, E-Series
Syntax
aggregate-address ipv6-address prefix-length [advertise-map map-name] [as-
set] [attribute-map map-name] [summary-only] [suppress-map map-name]
Parameters
ipv6-address
prefix-length
Enter the IPv6 address in the x:x:x:x::x format followed by the prefix length in
the /x format. The range is /0 to /128.
NOTE: The :: notation specifies successive hexadecimal fields of zeros.
advertise-map
map-name
(OPTIONAL) Enter the keywords advertise-map followed by the name of a
configured route map to set filters for advertising an aggregate route.
as-set (OPTIONAL) Enter the keywords as-set to generate path attribute information
and include it in the aggregate.
AS_SET includes AS_PATH and community information from the routes included in
the aggregated route.
attribute-map
map-name
(OPTIONAL) Enter the keywords attribute-map followed by the name of a
configured route map to modify attributes of the aggregate, excluding AS_PATH
and NEXT_HOP attributes.
summary-only (OPTIONAL) Enter the keywords summary-only to advertise only the aggregate
address. Specific routes will not be advertised.
suppress-map
map-name
(OPTIONAL) Enter the keywords suppress-map followed by the name of a
configured route map to identify which more-specific routes in the aggregate are
suppressed.
Defaults Not configured.
Command Modes CONFIGURATION-ROUTER-BGPV6-ADDRESS FAMILY
Command
History
Version 8.2.1.0 Introduced on the E-Series ExaScale.
Version 7.4.1.0 Introduced
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.
