Cisco – IPSec Tunnel Termination via HSRP
James ran into this one the other day, and I found it interesting. If you have routers configured for high availability(HA) using hot stand-by routing protocol(HSRP) and you are doing straight IPSec tunnels, how would one go about terminating the tunnel on the virtual HSRP IP address?

Cisco ASA IP SLA – Failover Routing
It seems like everytime I want to do something funky with an ASA, Cisco says “ASAs are not routers, use them what they are designed for.” This really doesn’t help me…heh.

Cisco 642-444 Call Manager 4.X -> Passed 😉
I snagged the callman test today. I wasn’t terribly worried, because I studied pretty thoroughly, but…I always get nervous. I find that if I chew gum during the test, it helps a LOT. I usually like to take the test first thing in the morning, that way I’m not thinking about it all day…hehe. I…
