group-name: Name of a peer group, a string of 1 to 47 characters. 

ip-address: IP address of a peer. 

number: Specifies the number of times for which the local AS number can appear in routes from the 

peer/peer group, in the range 1 to 10. The default number is 1. 

Use the peer allow-as-loop command to allow the local AS number to exist in the AS_PATH attribute of 

routes from a peer/peer group, and to configure the number of times the local AS number can appear.  

Use the undo peer allow-as-loop command to remove the configuration. 

By default, the local AS number is not allowed in routes from a peer/peer group.
