Hi All

Looking at this draft, is the objective to signal join/leaves of a Source specific Multicast (SSM) only and not ASM?

In addition it seems like this only will work for multicast in base routing and not mvpn i.e. I don’t see a route target or is the RD used for VRF identification, can you please verify this?

In addition just to understand why would you want to move the overlay from BGP to PCE?

Thanks
Hooman

Hi PCE experts,

At present,  the signaling of multicast is mainly distributed processing via BGP messages, and there is no centralized processing solution.
We submit a draft of unified management of BIER multicast signaling by controller via PCEP messages, which can combine the characteristics of BIER and improve the efficiency of interaction, as follows:
Registration of a multicast source to controller(PCE).
Report of joining/leaving message to controller(PCE).
Controller(PCE) sends BitStrings indicating the forwarding of packets in BIER network.

Any comments are welcome.
