for example), the AS_PATH attribute of a route from a peer must be allowed to contain the local AS number. Otherwise, the route cannot be advertised correctly. Examples # In BGP IPv4 unicast instance view, configure the number of times the local AS number can appear in AS_PATH attribute of routes from peer group test as 2. system-view [Sysname] bgp 100 [Sysname-bgp] ipv4-family unicast [Sysname-bgp-ipv4] peer test allow-as-loop 2 # In BGP-VPN IPv6 unicast instance view, configure the number of times the local AS number can appear in AS_PATH attribute of routes from peer group test as 2. system-view [Sysname] bgp 100 [Sysname-bgp] ip vpn-instance vpn1 [Sysname-bgp-vpn1] ipv6-family unicast [Sysname-bgp-ipv6-vpn1] peer test allow-as-loop 2 peer as-number (for a BGP peer) Use peer as-number to create a BGP peer and specify its AS number. Use undo peer to delete a BGP peer. Syntax peer { ip-address | ipv6-address } as-number as-number undo peer { ip-address | ipv6-address } Default No BGP peer is created. Views BGP view, BGP-VPN instance view Predefined user roles network-admin Parameters ip-address: Specifies the IP address of a peer. ipv6-address: Specifies the IPv6 address of a peer. as-number: Specifies an AS number for the peer, in the range of 1 to 4294967295. If the AS numbers of the peer and the local router are the same, the peer is an IBGP peer. If they are different, the peer is an EBGP peer. Usage guidelines You can also create a peer and add it to a peer group by using the peer group command. To modify the AS number of a peer, do not execute the peer as-number command repeatedly. Instead, you must first delete the peer and configure it again. 269
