Question

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?

Options

Aecmp-limit 10
Bcontroller-send-path-limit 10
Cmaximum-paths 10
Dsend-path-limit 10

Explanation

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.

Common mistakes.

A. 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.
B. controller-send-path-limit is not a standard Cisco Catalyst SD-WAN OMP command used for this specific purpose.
C. maximum-paths is typically used in traditional routing protocols to control ECMP, not to set the OMP vRoute path advertisement limit to controllers.
