Hi,

I'm wondering if Profile 10 (p2mp-te with static mapping in VRF) is supported in ASR9000 XR

I configured according to this link

http://www.cisco.com/c/en/us/support/docs/multiprotocol-label-switching-mpls/multiprotocol-label-switching-vpns-mpls-vpns/118983-configure-mpls-00.html#anc28

However it seems that something is broken

Also I notice that in the configuration guide for XR 5.3.x says that only the first 9 profiles are supported, can anyone clarify.

Thanks

Jacobo

Hello Jacobo,

Cisco implementation of NG MVPN uses mLDP not RSVP-TE based p2mp LSPs. So the answer to your question is that your configuration is not supported.

I have heard news of mLDP with NG MVPN on Vodafone Italy from a linkedin peer.

Also there was an aske the expert session two years ago where the host clearly stated that Cisco implementation supports only mLDP not RSVP TE p2mp.

This is the opposite of what does Juniper that supports RSVP TE p2mp LSPs on M and MX series.

Hope to help

Giuseppe

Hi Giuseppe, thanks for your answer,

I managed to get the configuration to work just yesterday, actually by mistake I didn't enable PIM on the loopback which was the root cause of the problem.

Now, aside from my lab is now working, it seems to me that it should be supported, I mean, the commands are there to support p2mp-te signaled by rsvp-te as the core tree, there is also a configuration guide for XR for it and also I found a couple of Cisco Live presentations that stats that this profile is supported in XR... hopefully somebody from the Cisco Business Unit will read this post and clarify if it is officially supported.

Best Regards,

Jacobo

Hello Jacobo,

I agree that in two years support for p2mp RSVP TE LSPs with NG MVPN can have been added.

I have to apologize for my previous answer.

If this is supported it opens scenarios of interoperability between Cisco and Juniper devices in the NG MVPN feature.

Hope to help

Giuseppe

ps. I have rated 5 your answer because it is something I have been waiting for years

Hi Jacobo - I am sorry, this post is almost 2 years back. But I am trying to make it on VIRL as of today, but I can't manage to do actual ping test over SSM group from a certain source from CE side.

But just to check, if you can share your PE head end and tail end config here. I tried already this config template from cisco config guide created by @Luc De Ghein but not sure what I miss.

Config guide from Cisco: https://www.cisco.com/c/en/us/support/docs/multiprotocol-label-switching-mpls/multiprotocol-label-switching-vpns-mpls-vpns/118983-configure-mpls-00.html#anc28

mVPN solutions using P2MP TE as core tree protocol do not work and are not supported on virtual XR routers (XRv and XRv9k) currently.

Regards,

Luc

respanto · ‎11-30-2017

Thank you so much, Luc. Got some feedback also that Profile 10 dataplane don't work in XRv.

Can you also confirm the Ingress Replication as Core Tree dataplane will not work in XRv/XRv9k? Since base on my lab test, it fails to send traffic from Sender to Reciever too and also RP distribution fail using BSR. :(

Below is just a note, maybe you have time to check it and have some comment. Thank you very much in advance.

Note: Now I understand, earlier I was confused about Core tree for Profile 20/22 & 24/26 since it is also P2MP-TE but the core tree is just P2MP( as indicated in one of the cisco live mVPN profile chart. Base on my test over VIRL, Profile 20/22 okay for both C-mcast traffic ASM/SSM but Profile 24/26 only work for C-mcast traffic SSM, I manage to test it successfully. Below is my test logs from Sender, Ingress and Egress PE and also one Core P router using profile 20.
