AFAIK, it's hard to find dedicated networking devices (and routing protocols!) which support them. 8-/ Yes, people use source based routing to block specific IPs and subnets, it's also needed to Mobile IPV4. Anyway, I've played a bit with something inspired by CEF (more precisely speaking, one diagram in the IOS internals book and some IOS diagnostic output). Thanks, Alexey and myself will need to study this deeply. Although, I hope it's not "too similar" to what CEF does because undoubtedly Cisco has a bazillion patents in this area. This is actually an argument for coming up with out own algorithms without any knowledge of what CEF does or might do. :( - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
