What is the purpose of the no-cspf command?
A.
to successfully signal the LSP across the network regardless of constraints
B.
to delete the CSPF database
C.
to ignore OSPF when calculating the ERO
D.
to successfully signal the LSP only if the default IGP path (or named path) meets all constraints
Answer should be A. D is what CSPF actually does
Yeah A should be correct since CSPF is An MPLS algorithm that has been modified to take
into account specific restrictions when calculating the shortest path across the network
But you can specify some constraints with RSVP like bandwith, even when CSPF is disable, so, D could be correct.
