Regards, Abdel 2011/12/12 Ben Hughes <[email protected]<mailto:[email protected]>> Hi guys, I've just been reviewing volume 1 lab 29 again. The one thing that has taken me a little while to work out is that the version of IOS I'm using is a little older (12.4(9)T7) and doesn't have the "bgp mpls forwarding" command that is (as I understand it) added automatically to the appropriate interface when you use the neighbor send-label command. My question is, if I add the "mpls ip" command under the appropriate interface (in the lab I'm talking about the serial link between R5 and R6), is this doing the same thing as the "bgp mpls forwarding" command? Everything does start working fine once I add it in. I'm just not sure if there are any differences and if not, why would Cisco add a different command that does the same thing? Any comments much appreciated. Cheers, Ben. _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com<http://www.ipexpert.com> Are you a CCNP or CCIE and looking for a job?
