[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 then the prefix length in the / x format.
The range is from /0 to /128.
NOTE: The :: notation specifies successive hexadecimal fields of zeros.
advertise-map
map-name
(OPTIONAL) Enter the keywords advertise-map then 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 then 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 are not advertised.
suppress-map map-
name
(OPTIONAL) Enter the keywords suppress-map then the name of a configured route

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, the
aggregate flaps 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 using the network command, that route stills appear in the routing table if the summary-
only
parameter is configured in the aggregate-address command.
The summary-only parameter suppresses all advertisements. If you want to suppress advertisements to only
specific neighbors, use the neighbor distribute-list command.
