This feature allows a SBFD initiator to request a SBFD reflector to respond to the status of an auxiliary path. This is very useful when an SBFD session couldn’t be established with an endpoint. In such a case the SBFD initiator could establish a session to a router in the path ( ex. ASBR ) to respond to the health of the remaining path ( ex. endpoint connected to the ASBR ). 

This feature allows customers to make the status of a MPLS static route dependent on the state of a BGP peer. When this feature is enabled for a static route, it will be programmed only if the monitored BGP peer session is up. 

This feature allows BGP speakers that support L2 EVPN to exchange system router MAC addresses of virtual gateway IP addresses configured on a SVI interface. The receiving device will treat these MAC addresses as local system router MAC addresses, if it has the same IP addresses configured as virtual IP addresses on the corresponding (Bridge ID) SVI interfaces.
