Hi, I'm currently running 17.2. Can you elaborate on how enhanced convergence is obtained on L2/L3 interfaces?
As an update to the situation, this is the progress so far:
1) For software upgrade, reboots, graceful shutdowns for maintenance scenarios, there the downing of all ae’s on the desired member works with little to no loss of traffic. Although it’s not a procedure I expect for this class of networking equipment, but at least there is a method I suppose.
2) For complete fail, hangs, or power failure on a member of the core pair:
If the standby member suffers from a complete unexpected sudden outage, there will be no to little (sub-second) loss of traffic.
However if the active member suffers from a similar failure, there will be about a 10 second outage to layer 3 traffic only. It’s not a lot but it’s still not acceptable for this level of network switching. I believe this is happening due to the fact that I've noticed the LACP downstream links have to reconverge where once completed, traffic then begins to resume.
Is this expected behavior with MC-LAG on EX platforms in a power-down failure scenario? Thanks,
