To define a BGP group in which the local system’s peers are dynamic and change over time, include the allow statement. To recognize all BGP systems as peers, include the allow-all statement. To recognize BGP systems within specified address ranges, specify a set of addresses in the allow network/mask-length statement. These addresses can be IPv6 or IPv4 addresses.

Note: You cannot define a BGP group with dynamic peers with authentication enabled. |
