Abstract
Systems and methods for propagating information on sources for a multicast group across an MVPN from a co-located RP and PE in a site of the MVPN are disclosed. Embodiments may monitor traffic at a network device comprising the co-located RP and PE to determine when a source sends traffic for a multicast group. When it is determined that traffic for a multicast group is being sent from a source an advertising message for that source and multicast group may be sent to the MVPN.
Claims20
A method, comprising:
- determining, at a network device acting as both an Rendezvous Point (RP) and a Provider Edge (PE) router at a site in a Multicast Virtual Private Network (MVPN), that a source is active for a multicast group;
- and
- sending an advertisement message to the MVPN in response to the determination that the source is active for the multicast group, the advertisement message indicating the source and the multicast group.
A network device, comprising:
- a processor;
- packet processing hardware adapted to determine source group hit data based on packets processed by the packet processing hardware at the network device;
- a non-transitory computer readable medium, comprising instructions executable on the processor to:
- implement a Rendezvous Point (RP) and a Provider Edge (PE) router for a site in a Multicast Virtual Private Network (MVPN);
- obtain source group hit data from the packet processing hardware;
- determine that a first directly connected source is active for a multicast group based on obtained source group hit data;
- and
- send an advertisement message to the MVPN in response to the determination that the first directly connected source is active for the multicast group, the advertisement message indicating the first directly connected source and the multicast group.

A non-transitory computer readable medium, comprising instructions for:
- obtaining source group hit data from packet processing hardware at a network device acting as both an Rendezvous Point (RP) and a Provider Edge (PE) router at a site in a Multicast Virtual Private Network (MVPN);
- determining, based on obtained first source group hit data, that a first source is active for a first multicast group, wherein the first source is directly connected to the network device;
- and
- sending an advertisement message to the MVPN in response to the determination that the first source is active for the first multicast group, wherein the advertisement message indicates the first source and the first multicast group.
