Hierarchy Level


Specify the cluster identifier to be used by the route reflector cluster in an internal BGP group.


If you configure both route reflection and VPNs on the same routing device, the following modifications to the route reflection configuration cause current BGP sessions to be reset:

  • Adding a cluster ID—If a BGP session shares the same AS number with the group where you add the cluster ID, all BGP sessions are reset regardless of whether the BGP sessions are contained in the same group.

  • Creating a new route reflector—If you have an IBGP group with an AS number and create a new route reflector group with the same AS number, all BGP sessions in the IBGP group and the new route reflector group are reset.


If you change the address family specified in the [edit protocols bgp family] hierarchy level, all current BGP sessions on the routing device are dropped and then reestablished.
