weight | Neighbor weights assigned to BGP peer groups
Incoming update distribute list | Distribute list for incoming routes, if configured
Outgoing update distribute list | Distribute list for outgoing routes, if configured
Incoming update filter list | Update filter list for incoming routes, if configured
Outgoing update filter list | Update filter list for outgoing route, if configured
