Abstract
A system, method and apparatus for source redundant MVPN in which a number of Interface Indices is reduced by leaf node Incoming Label Maps (ILM) including one or more Interface Indices common to multiple tunnels.
Claims19
A method for providing Multicast Virtual Private Network (MVPN) source redundancy, the method comprising:
- configuring a leaf node to use a first logical interface to receive data associated with a multicast channel from each of a Primary Source inclusive provider multicast service interface (I-PMSI) tunnel and a Primary Source selective provider multicast service interface (S-PMSI) tunnel;
- and
- configuring said leaf node to use a second logical interface to receive data associated with said multicast channel from each of a Secondary Source I-PMSI tunnel and a Secondary Source S-PMSI tunnel.
An apparatus for providing Multicast Virtual Private Network (MVPN) source redundancy, the apparatus comprising:
- a processor configured for:
- configuring a leaf node to use a first logical interface to receive data associated with a multicast channel from each of a Primary Source inclusive provider multicast service interface (I-PMSI) tunnel and a Primary Source selective provider multicast service interface (S-PMSI) tunnel;
- and
- configuring said leaf node to use a second logical interface to receive data associated with said multicast channel from each of a Secondary Source I-PMSI tunnel and a Secondary Source S-PMSI tunnel.
A non-transitory computer readable storage medium storing instructions which, when executed by a computer, cause the computer to perform a method for providing Multicast Virtual Private Network (MVPN) source redundancy, the method comprising:
- configuring a leaf node to use a first logical interface to receive data associated with a multicast channel from each of a Primary Source inclusive provider multicast service interface (I-PMSI) tunnel and a Primary Source selective provider multicast service interface (S-PMSI) tunnel;
- and
- configuring said leaf node to use a second logical interface to receive data associated with said multicast channel from each of a Secondary Source I-PMSI tunnel and a Secondary Source S-PMSI tunnel.
A computer program product wherein computer instructions, when processed by a computer, cause the computer to perform a method for a providing Multicast Virtual Private Network (MVPN) source redundancy, the method comprising:
- configuring a leaf node to use a first logical interface to receive data associated with a multicast channel from each of a Primary Source inclusive provider multicast service interface (I-PMSI) tunnel and a Primary Source selective provider multicast service interface (S-PMSI) tunnel;
- and
- configuring said leaf node to use a second logical interface to receive data associated with said multicast channel from each of a Secondary Source I-PMSI tunnel and a Secondary Source S-PMSI tunnel.
