NO.9 For which purpose is the command mpls ldp maxhops used?
A. In large ATM-MPLS networks, the LFIB can become too large and it may be necessary to limit the
maximum diameter of the MPLS LSPs.
B. Because downstream-on-demand label allocation uses hop count to control loop detection, it maybe
necessary to limit the maximum diameter of the MPLS network.
C. Because end-to-end delay can cause problems with some voice applications, it may be necessary to
limit the maximum diameter of the MPLS network.
D. When interconnecting large frame mode MPLS and cell mode networks it may be necessary to limit the
maximum network diameter to prevent forwarding loops.
