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.
CEF is required on Cisco routers to support MPLS because that is the forwarding mechanism IOS uses to create the LFIB. Other vendors will have their own forwarding mechanism and they may have their own requirements that must be configured in order for MPLS to operate.
TDP was Cisco's original Labael Distribution Protocol, but LDP has become the standard and all development of new features and enhancements is being done on LDP, not TDP. TDP does not support any of the advanced LDP features since development on it has been stopped for a number of years now.
Using LDP allows multivendor interoperability even if your network is all Cisco when you deploy MPLS. Using LDP from the start allows you to avoid any TDP to LDP migration you may have to go through if you introduce another vendor.
