Trace back to when this started...  The freakiest things I have seen in this area, are caused by incompatible boot ROM's.  If you have a 2500, you need install the 11.0 (10c) model (they are free from Cisco).  The part # is BOOT-2500=.  I have also seen this issue when the IOS image is small

In the near to moderate term, I really don't expect to see the ability to have SLA's across arbitrary Internet connections. I do see the ability for specific ISPs to offer SLA's on IP-based (i.e., not necessarily public Internet) paths. The reason for doing this is as much, or more for busines

Derek, Redundant? No way. The TCP header information is very unique in itself. Think about this.. IP (layer 3) is connectionless and therefore makes no guarantee that the data will received by the destination, whereas TCP (layer 4) is connection-oriented and is there to provide the
