RSVPTE

Hi, please your help

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:

#

mpls lsr-id 192.168.0.1

mpls

 mpls te

 mpls rsvp-te

 mpls te cspf

interface Tunnel1/0/0

tunnel-protocol mpls te

destination 192.168.0.3

mpls te tunnel-id 1

mpls te path metric-type igp

mpls te igp metric absolute 1

mpls te commit

#

Which path will be selected when the tunnel becomes Up? What is the metric of this tunnel?

a. RTA—RTB—RTC; 1

b. RTA—RTD—RTE—RTC; 1

c. RTA—RTB—RTC; 20

d. RTA—RTD—RTE—RTC; 3
