We never really want to talk IS-IS with random crap - in that case the protocol of choice would be BGP. > I run into this a lot in the security appliance space, where you want > your security appliances to either learn or advertise routes internally > (VPN tunnel reachability is a big reason for this), but also in devices > such as load balancers and other middlebox cruft that occasionally needs > to participate in routing advertisement/subscription. ... > The ones who actually care about making it work almost always include > RIP and OSPF, with a few shout-outs to BGP. IS-IS (and OSPF v3) rarely > makes the cut. We've found that BGP works reasonably well to talk with such boxes, and also that BGP is generally available.
