Release Information

Statement introduced in Junos OS Release 20.2R1.


Define a policy to specify a list of BGP autonomous systems (AS) to configure acceptable AS ranges for EBGP groups that can be used for bringing up BGP peers while establishing a BGP session. BGP accepts a peer request based on the specified AS range and rejects a peer request if the AS does not fall into the specified range. This allows you to control BGP peering when the neighbor’s exact IP address is not known.


nameSpecify a name to identify a BGP as-list.
membersSpecify a single autonomous system number or a range of autonomous system numbers in plain numbers.
