A. ADSPEC sets an SDP's MTU to the smallest MTU value found along the LSP path.

B. ADSPEC can be enabled on individual LSPs.

C. ADSPEC can automatically adjust the service MTU.

D. RSVP must be enabled on all MPLS routers of a path to use ADSPEC.

A. It supports LSPs with traffic engineering constraints.

B. It supports traffic protection using IGP equal cost paths.

C. It supports LSPs that follow the IGP best path.

D. It supports CAC to prevent resource overbooking.

A. 8022

B. 7958

C. 8042

D. 7978

A. Convergence is triggered when the physical interfaces between routers R1 and R2 go down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

B. Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

C. Convergence is triggered when the switches notify the routers about the link state information. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged

D. Convergence will not be triggered because switches cannot run routing protocols between them.

E. Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of Hello timeouts. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.

A. Hello and Dead Intervals

B. Area ID

C. DR and BDR addresses

D. The list of neighbors

E. Stub flag
