Checking the MPLS and RSVP Configuration

This chapter describes how to verify the correct configuration of both the Multiprotocol Label Switching (MPLS) protocol and Resource Reservation Protocol (RSVP). Incorrect configuration of either protocol prevents successful label-switched path (LSP) creation. (See Table 6.)
