Default None
Command Mode ROUTER-BGPv4-AF
Usage Information At least one of the routes that is included in the aggregate address must be in the BGP routing table for the
configured 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 flaps to track changes in the AS_PATH. The no
version of this command disables the aggregate-address configuration.
Example
OS10(conf-router-bgpv4-af)# aggregate-address 6.1.0.0/16 summary-only
Supported
Releases
10.3.0E or later
allowas-in
Configures 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 specified 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

Command Mode ROUTER-BGP
Usage Information After you use this command, use the clear ip bgp * command to recompute the best path. The no version
of this command resets the value to the default.
NOTE: To configure these settings for a nondefault VRF instance, first enter the ROUTER-
CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter ROUTER BGP VRF mode using the vrf vrf-name
command.
