Hi Shawn Just for your information
At one time we had issue with VRRP between the ASR920, we contact Cisco TAC and we did troubleshoot with I believe 2 or 3 level of support team. The issue got fixed be just reboot both device then VRRP works ever since . Lucky our setup is not a production setup ... -----Original Message----- From: cisco-nsp <cisco-nsp-boun...@puck.nether.net> On Behalf Of Shawn L Sent: Monday, 1 June 2020 1:57 AM To: James Bensley <jwbensley+cisco-...@gmail.com> Cc: Cisco Network Service Providers <cisco-nsp@puck.nether.net> Subject: Re: [c-nsp] ASR920 Interface won't come up James I have spoken to TAC, but no resolution as of yet. After getting all of the pertinent information, my TAC engineer dropped off the face of the earth for several weeks, then e-mailed me for times to discuss, then went dark again. I have to say, I'm not impressed. We've done some debugging on our own, but not goten real far. We've tried several reboots of the far-end, and we aren't able to reproduce it or make it fail.
