aggregate-address
Summarizes a range of prexes to minimize the number of entries in the routing table.
Syntax
aggregate-address address/mask [as-set] [summary-only] [advertise-map map-name]
{attribute-map route-map-name] [suppress-map route-map-name]
Parameters
• address/mask — Enter the IP address and mask.
• as-set — (Optional) Generates AS set-path information.
• summary-only — (Optional) Filters more specic routes from updates.
• advertise-map map-name — (Optional) Enter the map name to advertise.
• attribute-map route-map-name — (Optional) Enter the route-map name to set aggregate attributes.
• suppress-map route-map-name — (Optional) Enter the route-map name to conditionally lters specic
routes from updates.
Default None
Command Mode ROUTER-BGPv4-AF
Usage Information At least one of the routes included in the aggregate address must be in the BGP routing table for the congured
aggregate to become active. If routes within the aggregate are constantly changing, do not add the as-set
parameter to the aggregate because the aggregate aps to track changes in the AS_PATH. The no version of this
command disables the aggregate-address conguration.
Example
OS10(conf-router-bgpv4-af)# aggregate-address 6.1.0.0/16 summary-only
Supported Releases 10.3.0E or later
allowas-in
Congures the number of times the local AS number can appear in the BGP AS_PATH path attribute before the switch rejects the route.
Syntax
allowas-in as-number
Parameters as-number—Enter the number of occurrences for a local AS number, from 1 to 10.
Default Disabled
Command Mode ROUTER-BPG-NEIGHBOR-AF
Usage Information Use this command to enable the BGP speaker to accept a route with the local AS number in updates received from
a peer for the specied number of times. The no version of this command resets the value to the default.
Example (IPv4)
OS10(config-router-neighbor)# address-family ipv4 unicast
OS10(conf-router-bgp-neighbor-af)# allowas-in 5
Example (IPv6)
OS10(conf-router-template)# address-family ipv6 unicast
OS10(conf-router-bgp-template-af)# allowas-in 5
Supported Releases 10.3.0E or later
