undo aggregate ip-address { mask | mask-length } In BGP IPv6 unicast instance view: aggregate ipv6-address prefix-length [ as-set | attribute-policy route-policy-name | detail-suppressed | origin-policy route-policy-name | suppress-policy route-policy-name ] * undo aggregate ipv6-address prefix-length Default No summary route is configured. Views BGP IPv4 unicast instance view, BGP-VPN IPv4 unicast instance view, BGP IPv6 unicast instance view Predefined user roles network-admin 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 two routes 10.1.1.0/24 and 10.1.2.0/24 exist in the BGP routing table, configuring the 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 attributes, the summary route does not have the ATOMIC_AGGREGATE attribute carries all the COMMUNITY attributes. 196

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
two routes 10.1.1.0/24 and 10.1.2.0/24 exist in the BGP routing table, configuring the
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 attributes, the summary route does not have the
ATOMIC_AGGREGATE attribute carries all the COMMUNITY attributes.
