For protocols that live somewhere between layer 2 and layer 3 they have some
unique needs from the layer 3 protocols.
To be specific MPLS needs to store labelling information for each entry in the
FIB. If the FIB had a protocol specific field (or set of fields) and a set
of access functions for these fields then MPLS wouldn't have to be so intrusive
in the FIB code.
I have code that already meets the needs of MPLS but would like to get
feedback from the list:
-Are there other protocols that could take advantage of protocol specific
fields in the FIB?
-Is this even a good idea?
