Parameters
ip-address: Specifies a summary address.
mask: Specifies a mask for the summary address, in dotted decimal notation.
mask-length: Specifies a mask length for the summary address, in the range of 0 to 32.
ipv6-address: Specifies an IPv6 summary address.
prefix-length: Specifies a prefix length for the IPv6 summary address, in the range of 0 to 128.
as-set: Enables the AS_PATH attribute of the summary route to contain the AS path information of all
summarized routes. The AS_PATH attribute is of the AS_SET type that requires no sequence when
arranging AS numbers. If this keyword is not specified, the AS_PATH attribute of the summary route
contains only the AS number of the local router.
attribute-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to
63 characters, to set attributes for the summary route.
detail-suppressed: Advertises only the summary route. If this keyword is not specified, BGP advertises
both the summary route and the more specific routes.
origin-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters, to select routes to be summarized.
suppress-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to
63 characters, to filter more specific routes to be advertised. Routes permitted by the specified routing
policy are not advertised. Routes denied by the specified routing policy are advertised.
Usage guidelines
This command creates a summary route. If the BGP routing table has routes whose destination addresses
fall within the specified network, the summary route is added to the BGP routing table. For example, if
t w o r o u t e s 10 .1.1. 0 / 24 a n d 10 .1. 2. 0 / 24 e x i s t i n t h e B G P r o u t i n g t a b l e , c o n f i g u r i n g t h e aggregate
10.1.0.0 16 command creates a summary route 10.1.0.0/16.
If the summarized routes have different ORIGIN attributes, the summary route selects the ORIGIN
attribute in the sequence of INCOMPLETE, EGP, and IGP. For example, if the ORIGIN attributes of the
summarized routes include INCOMPLETE and IGP, the ORIGIN attribute of the summary route is
INCOMPLETE.
If the summarized routes have different COMMUNITY (or extended community) attribute values and the
summary route does not have the ATOMIC_AGGREGATE attribute, the COMMUNITY attribute of the
summary route carries all the COMMUNITY (or extended community) attribute values.
