Hi there,
I am having trouble testing a new back-to-back vPC setup.
I have two vPC domains connected:
1a(pri) <--> 2a (pri)
1b(sec) <--> 2a (sec)
I have setup some continous pings behind vPC's connected to classical etherchannel switches.
When we reload the secondary (1b) we just loose maybe 1 ping.
When we reload the primary (1a), we loose connectivity for about 30sec? Which should not be the case in a typical vPC setup.
I have tried to look in the most obvious parameters but couldn't find any lead.
The only thing I can see in the system internal logs i can't explain and maybe leads to the possible cause:
2017 Dec 28 15:05:16.543991 vpc: Unexpected Event [24] received on peer-link [1]
The ICMP replies stop just after the vPC PL comes back online.
Delay-restore = 180s
Auto-recovery = 240s
Any help is kindly appreciated!
