Support for new streams during VLTi failure

If the VLTi fails, MAC addresses that are learned after the failure are not synchronized with VLT peers. Thus, the VLTi failure leads to

continuous ooding of trac instead of unicast.

If the VLTi links fail, MAC and ARP synchronization does not happen. As a result, the system oods L2 packets and drops L3 packets.

For example, in the following gure, after the VLTi is down, VLT peer1 learns the MAC address of Host 2:

Because the VLTi link is down, VLT Peer 2 is not synchronized with the MAC address of Host 2 . If the trac from Host 1 is sent to VLT

Peer 2, then VLT Peer 2 oods the trac.
