NG-MVPN support in Cisco

[narainarun]

Hi All,

Does Cisco support Next Generation - Multicast VPN (Draft-ietf-l3vpn-2547bis-mcast-01.txt) . I could see Juniper is doing it aggressively but could not get any concrete docs in cisco and if not available in Cisco any road map when it can be incorporated?

thanks in advance

Hello Arun,

I'm not part of Cisco so my answer is not representative of Cisco at all.

Juniper NG MVPN is based on MP BGP and uses RSVP TE P2MP LSPs and does not require PIM in the core or the use of GRE encapsulation as in draft Rosen. I have had exposure to NG MVPN and it is a good technology that is becoming stable.

It is quite to complex to understand all the interactions in the signaling plane but it has the scalability of iBGP ( route reflector servers and so on)

NG MVPN builds on a standard L3 unicast VPN.

Cisco is starting to support LDP MP2MP LSPs but it puts multicast traffic on it by means of a form of local switching so it is a good match for broadcast, multicast and unknown traffic in a VPLS  (BUM). so it is L2 in nature

However, I have heard that NG MVPN with MP BGP signaling plane is on the road map for Cisco IOS XR and that will open interesting interoperability scenarios as currently there is no interoperability at all between the two cases described above,

Let's wait for some Cisco folk to give us confirmation of the road map

Hope to help

Giuseppe

Hi Giuseppe,

Thank you very much for reply. Lets wait to hear from Cisco.

thanks

Hi Giuseppe,

I can understand that while using NG-MVPN , no need to enable multicast within the core (No PIM & no multicast-rotuing). That is a good thing , but do we need any other desingn change within the core (Ex: P2MP LDP or MP2MP LDP) ?

What about the RP  ? as in this case there is no Provider RP. So there will be only C-RP which need to be configured on the PEs and on the CEs ?

Thanks,

Anil.
