QUESTION 451 The engineer must augment the vRoute path limit to 10 for Cisco Catalyst SD-WAN controllers via CLI. Which configuration command meets the requirement under OMP?

The correct answer is D. send-path-limit 10. The send-path-limit command under OMP configuration specifies the maximum number of TLOC paths advertised for a vRoute from a WAN Edge router to the vSmart controller.

Why each option

The `send-path-limit` command under OMP configuration specifies the maximum number of TLOC paths advertised for a vRoute from a WAN Edge router to the vSmart controller.

Aecmp-limit 10

`ecmp-limit` specifies the maximum number of equal-cost paths used for forwarding traffic, not the number of TLOC paths advertised for a vRoute by OMP.

Bcontroller-send-path-limit 10

`controller-send-path-limit` is not a standard Cisco Catalyst SD-WAN OMP command used for this specific purpose.

Cmaximum-paths 10

`maximum-paths` is typically used in traditional routing protocols to control ECMP, not to set the OMP vRoute path advertisement limit to controllers.

Dsend-path-limit 10Correct

The `send-path-limit` command, configured within the OMP section on a WAN Edge router, directly controls the maximum number of TLOC paths associated with a vRoute that the router sends to the vSmart controller. Setting this to 10 directly meets the requirement to augment the vRoute path limit.
