Switch# configure terminal Switch(config)# router bgp 65100 Switch(config-router)# neighbor 10.4.4.4 advertisement-interval 15 Switch(config-router)# 13-45 neighbor allowas-in (MI and EI Mode Only) This command is used to enable routers to allow their own AS appearing in the received BGP update packets. Use the no form of this command to disable a duplicate AS number. neighbor {IP-ADDRESS | IPV6-ADDRESS | PEER-GROUP-NAME} allowas-in [NUMBER] no neighbor {IP-ADDRESS | IPV6-ADDRESS | PEER-GROUP-NAME} allowas-in Parameters IP-ADDRESS IPV6-ADDRESS PEER-GROUP-NAME NUMBER Specifies the IP address of a BGP peer. Specifies the IPv6 address of a BGP peer. Specifies the name of a Border Gateway Protocol (BGP) peer group. The maximum length is 16 characters. (Optional) Specifies the maximum number of local AS, allowed to appear in the AS-path attribute of update packets. The value is from 1 to 10. If no number is supplied, the default value of 3 times is used. Default By default, this option is disabled. Command Mode Router Configuration Mode. Address Family Configuration Mode (IPv4 Unicast, IPv6 Unicast, and VRF). Address Family Configuration Mode (IPv4 Multicast, L2VPN VPLS and VPNv4). (MI Mode Only) Command Default Level Level: 12. Usage Guideline The BGP router will do AS path loop checks for the received BGP update packets. If the BGP router's own AS appears in the AS path list, it is identified as a loop and the packets will be discarded. If the allowas-in setting is enabled, the BGP router's own AS is allowed in the AS path list. 214
