Am studying for the ISCW exam and am confused on MPLS. Can MPLS be run on non Cisco routers?
Reason why I ask is because CEF must be enabled on the router before you can run MPLS, however CEF is Cisco propriatary. Then this leads me onto my next question. If you do have Cisco routers across your MPLS network, then why not run the TDP label protocol (or shall I say tag protocol)? Why go for the LDP industry standard when you are on Cisco routers anyway?
I know this is an obvious answer and doubt this particular question will show up on my exam (I hope!) but could someone please put my curiousity to rest.
Thanks in advance
