ASR9k N7K LPTS and OSPF

[Pavel Vrastiak]

Hello,

I was curious after seeing Cisco Live slides and I configured:

lpts pifib hardware police
 no flow ospf unicast known rate 0
 no flow ospf unicast default rate 0

on my ASR9010. I have only point to point interfaces with my neighbors in OSPF. However, after 45 minutes I have lost routes from NX7k and only from these. Other platforms were fine. Neighborship was fine though, I saw FULL state with everyone, just no routes. Does anyone know why, please?

Hi Pavel,

This is due to Nexus sending ospf updates on unicast address instead of multicast.

There is a enhancement bug opened on Nexus for the same.

Best Regards,

Bheem
