Multicast group IP address

To match a <S,G> the source needs to be present in the multicast source-address leafref and the group needs to present in the group-address leafref. To match a <*,G> the group has to be programmed in the group-address leafref and no source in the source-address leafref. Group address can be configured as a prefix.

Multicast Source IP address

Source address can be configured as a prefix.
