Comment 1 for bug 1653479

Hi Manish,

1. Topology file before and after issue is attached as requested.

2. Also what was the multicast replicator shown on QFX4 and QFX11 for working and non-working VN mentioned in bug. It is shown under ovsdb mac-table.

It seems that mac is learning correctly and QFX transefer traffic to TSN.
However,when this issue occured, Non-working VN(broken BUM Tree) could not Multicast communication.
