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:
