Question

Which configuration enables route filtering in an SD-WAN controller?

Options

Aomp filter-route inbound tloc-color
Bomp filter-route outbound tloc-color
Ctloc-route tloc-color inbound
Domp filter-route tloc-color

Explanation

Route filtering in an SD-WAN controller is configured under the OMP (Overlay Management Protocol) context using 'filter-route outbound tloc-color' to control which routes are advertised based on their TLOC color.

Common mistakes.

A. 'inbound' filtering for 'tloc-color' would filter routes coming into the vSmart, which is less common for influencing routing decisions from the vSmart to the edges based on TLOC color for path preference.
C. 'tloc-route' is not a valid top-level command for route filtering in the OMP context on a controller; filtering is done under 'omp' mode.
D. The command 'omp filter-route tloc-color' is incomplete and syntactically incorrect; it is missing the direction ('inbound' or 'outbound').
