Hello all, Recently we had a short outage because one of our two bgp-peers (the one with best path) accidentally looped their network. Our network setup is as following; Two routers, one eBGP peer on each and iBGP in-between the routers. What can I...

Will it only make STP converge slower? Or are there any other consequences to be concerned about?Thanks!

Thanks, this was the information I was looking for. Is this a general good practices for handling issues like this? Or is there any other way? If I where to enable this on my both eBGP peers and google's dns went down I could see a huge issue... ;)

Yes, what I mean is that one of the ISP's that I had a BGP session with had a network issue inside their network where packets where looped between two of their routers. This caused incoming and outgoing traffic to me get stuck in this router loop. S...

Correct, the time is just after the incident was resolved by shutting ports. What even more confuses me is that I see "last change occurred 1d15h ago from TenGigabitEthernet1/50". These ports, TenGigabitEthernet1/50 and TenGigabitEthernet1/49 are not...

Reason I ask is that we recently experienced a (presumed) STP loop and I'm trying to figure out if our server ports that did not have portfast could have been involved in making a loop.

So basically, if I have a port connected to a server and it's NOT configured as an edge port (portfast) the only drawback I will see is a 30-50 second inactive port?
