Refer to the exhibit. During a vPC peer switch reload, there is packet loss between the server and the router. Which action must be taken to prevent this behavior during future reloads?
A.
Set the routed uplink ports of the Cisco Nexus peers as orphans.
B.
Increase the vPC delay restore timer.
C.
Disable vPC ARP synchronize on the vPC peers.
D.
Decrease the OSPF hello and dead interval timers.
vPC Delay Restore
After a vPC peer device reloads and comes back up, the routing protocol needs time to reconverge.
The recovering vPCs leg may black-hole routed traffic from access to core until Layer 3 connectivity is
reestablished.
B is correct - we allow time for the vpc to learn all the routing and have all its interfaces ready before we preempt on the reloaded switch
