We have 2 switches interconnected and having 2 links on each switch all the links are having OSPF on P2P links from node and as well interlink of the switches. When we disable the OSPF on switch02 there is no packet loss but when enable it observed packet loss.

Tried to disable the ospf on Switch01 as well but still observing the packet loss, Configuration of ports are same on both sides. Kindly find below the configs i have on switches.

Hi Waqas,

Could you please let us know the platform, Exos version, port numbers, sharing algorithm, traffic details, OSPF status at the time of issue?

Also how you are confirming there is a packet loss.
