Went on an customer “ride-along” with Advanced Services this week. Customer’s requirement was that the DMVPN headend have 2 physical interfaces for High Availability. These 2 interfaces need to be the same subnet because they are going into 2 firewalls: one active/one standby. So now what?
Tom Kunath (Advanced Services) thought “Well…. what about using backup interface command?” Hmmmm that does seem to be the perfect tool in the Cisco CLI toolbox for this very situation.
Time to play in the lab!!!
So now let’s try it and see how per-tunnel QoS will work with it.
Class-Maps and Policy-Maps
NOTE: Snuck these configs from the QoS Chapter of the upcoming CiscoPress IWAN book a super dear friend of mine (David Prall) is co-authoring.

Send Traffic
Kay… so far so good. I also have both being sent at the same bps from the traffic generator so I wanted to check this also.
Time to Fail Primary Link!
Before I congest and see if the applied PerTunnel QoS can also drop. Let’s make sure Continue reading

I was asked many, many times about Tom’s Corner. What was it? Why was it important? Did you really start it? The real answer is that I’m a bit curious. I want to meet people.
