Subject Re: Very slow Virtual Router provisioning with 4.9.2.0
Date Wed, 03 May 2017 09:02:31 GMT
Another reason of slow can be VR configuration(persistent VR configuration design).  When one
component config apply, whole VR configuration apply is executed. Due to this the VR boot
up time will increase.

Thanks,
Jayapal
