We run a pair of ASA's with a Botnet license. Recently (like this week) I have been noticing an increase of dynamic filter alerts for IP 65.55.239.168. This is a registered Microsoft IP, which makes me suspect that someone is running possibly a DNS...

I have a 7200VXR running static, eigrp, and ibgp/ebgp. This router has a LAN interface and two serial interfaces each attached to a DS3. I have a route-map that I believe should be using "AND" logic which must match all conditions for the route act...

I have, but the IPSec appliance cannot run BGP. Yes, this scenario is a bit complicated, but gets less each day that passes. By the end of July, this will no longer be an issue and the current PBR will work as designed. I was just trying to find a...

Hey Harold,That makes perfect sense. I tested it in my lab and does work, however I see one issue. There is no built in mechanism for failover for an IPSec network learn via IGP. Failover does still work for BGP. Currently failover works like thi...
