Have Respect For The Work You Do

The other day I was called in to assist with issue that had been open for a few days. The primary reason for my involvement was to confirm network connectivity was permitted as required by a recently installed application.

Monitoring VRFs on IOS-XR

Lately I have been investigating how to monitor BGP peering session via SNMP instead of traps/syslog messages and I found out that this feature is not documented properly for IOS XR. Finally I managed to get it working, so I thought that it would be worth sharing with the community. In our example, we have […]

Consider an International Relocation

Over three years ago I saw an opportunity to take an assignment to my company HQ in Seattle. After debating this for some time with my wife we took the plunge and moved to the US. The question is, “was it worth it?”. For me the answer is an overwhelming ‘yes’.  I’m moving back to […]

Barbie films (yes, I really am talking about Barbie in a network blog post) are a big hit with my kids, and surprisingly with me too.
