you can blow it with is-is, just as you can with ospf, just as you can with pretty much any dynamic [routing] protocol. though i am an is-is fanboy, i would not blame the protocol. and if they can not manage the currently deployed protocol, i am not sure i would recommend they try a delicate transition. randy
