Hi Olive I have a one more query with HA mode . can we configure both NSR and NSF together , and if so during switchover which one is triggered first NSR or NSF .
I have two reasons for going into this deployement approch. 1> If someof my neighbour is not NSF capable or by mistake NSF gracefull config is not enabled or removed from any neighbour.NSR will take care for those neighbours. 2> During testing on CRS with scalability figures ,after switchover it was taking 4 mins of time to fully sync all the routing information with standby and if there is one more switchover during that time span , NSF can take care. What do you suggest as best practice deployements for NSR/NSF considering above two points.
