I might be reading this wrong but it appears only one person has raised an issue and then not actually backed it up with data. Out of the eyes that have views inside the major networks did anyone see any issues? Surely cross posting this to other NOG lists is sufficienct. On Sat, 26 Jan 2019 at

Erik, That’s a nice little script. Thanks! So you want a warning if a router hasn’t been rebooted in a long time? Just out of curiosity, why? I’m kind of glad that my routers don’t reboot, pretty much ever. Usually I want to know if the uptime suddenly became less than the most recent uptime,

Quick Script to check the uptime of ASR920's

All, I just created a quick script to check the uptime of a ASR920 via SNMP if you have a fairly long list of devices. It's a simple bash script and snmpwalk version 2c. Figured I would share it with you. Happy Friday Grab the code from GitHub: https://github.com/esundberg/CiscoRouterUptime It'

If I understand this thread correctly, the test cause no actual change in the routing table size or route announcement. That was all a result of the incorrect behavior of the software. Instead of throwing rocks, how about some data instead. We can collaborate and better understand the whole thing

It does, Ytti. And not just in testing. In feature development too. Often in design discussions, someone pipes up: "someone does bla bla, Let's not break it".

I'm personally aware of dozens and dozens of OSPF deployments, but not aware of a single IS-IS deployment. This is among smaller consumer ISPs, with typically up to around 10K customers. I'm sure a big reason for this is that IS-IS support isn't all that common in the lower end routing gear ofte

You’re probably right that there a lot more in service devices that are running OSPF. But IS-IS assuredly is involved in routing way more traffic volume. In the end , right tool for the job is all that matters. On Fri, Jan 25, 2019 at 09:17 Steven Bahnsen wrote: > Hi, > > First time poster loo
