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 227.7.7.7 repeat 10

 

Type escape sequence to abort.

Sending 10, 100-byte ICMP Echos to 227.7.7.7, timeout is 2 seconds:

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.

 

Cheers,

Cuong.

Hello,

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

Thanks,

Ato
