up the MPLS network must be RP-D, RP-DV or RP-C, RP-CV. RP-A and RP-A1 will
not operate.
In addition, in regard to the conditions of NIFs that support MPLS functions, NIF
conditions that accommodate MPLS backbone circuits are shown in Table 4-47 and
NIF conditions that accommodate MPLS access circuits are shown in Table 4-51
Refer to Figure 4-7 for the location of MPLS backbone and access circuits.
There are non-utilizable RP types depending on the mode of the MPLS protocol used.
These are shown in the table below.
