Multicast -- Multicast VPN --- XRv

Would like your assistance please regarding below quesitos


1- As you know to verify multicast we can use ping.

My problem is that when you ping using source loopback address it does not work [spare-mode is configured normally under loopback] however when you configure using outgoing interface it pings normally

What could be the reason for this ?


2- Does XRv simulator works fine with multicast. I am having very strange behavior is that OIL list is always null although source is directly connected. Not sure if its a bug or XRv issue


R8#ping repeat 10


Type escape sequence to abort.

Sending 10, 100-byte ICMP Echos to, timeout is 2 seconds:

Hi Sherif Ismail,I

Hi Sherif Ismail,

I encountered this and checked around. It seems that XRv supports Control-Plane features fully - BGP/IGP/LDP/PIM/etc. will work. However, Data-plane is supported with limitations.

Hello,I just installed XRv 5


I just installed XRv 5.2.0. Shall I expect MVPN data plane work?
