I simply cannot ping the SVI interface of Cat1. If I do a "sho arp" I can see the mac of R1 however. When I run "debug ip packet" I see "encapsulation failed" I've tried other 3725 IOS versions and I get the same result. I'm wondering if this might be a bug in dynamips? Strange thing is that if I use a 3640 image and tweak my .net file I can ping the SVI. Has anyone else had this problem? What versions of 3725 IOS are you guys running? Thanks I appreciate everyone's help!
