As shown in the figure, RTA, RTB, RTC are interconnected over IS-IS, RTA, RTD, RTE, and RTC are interconnected over OSPF. Both IS-IS and OSPF use the default costs. RSVPTE is enabled on all routers and the interfaces between these routers. The Loopback0 interface of RTC is 192.168.0.3/32 and is advertised in both OSPF and ISIS areas. 192.168.0.3/32 is also the LSR ID of MPLS. Configurations of the MPLS and tunnel on RTA:
