   Which OMP route is selected if it was learned from the same Cisco SD-WAN device at location S4406T9E02F15?

   • Aroute with the lower origin metric
   • Broute with the higher OMP route preference value
   • Croute with the higher router ID
   • Droute with the lower administrative distance

   Show answer

   Answer: D

   Explanation

   1) Prefer ACTIVE routes over STALE routes. 2) Select routes that are Valid. 3) Prefer routes with lower administrative distance (AD) (on vEdge only). AD is a locally-significant value on each router and depends on the OS. 4) Prefer routes with a higher route preference value. By default, all omp routes have 0 preference. 5) Prefer routes with a higher TLOC preference value (on vEdge only). TLOC preference is a parameter in TLOC routes. 6) Compare the origin type 7) Compare the origin metric - prefer lower metric so I would go with D

   Which protocol advertises WAN Edge routes on the service side?

   • AOSPF
   • BBGP
   • CISIS
   • DEIGRP

   Show answer

   Answer: A

   Explanation

   Route Redistribution—Default Behavior OMP automatically redistributes the following types of routes that it learns either locally or from its routing peers: • Connected • Static • OSPF intra-area routes • OSPF interarea routes All other routing protocols require explicit configuration to enable redistribution. So OSPF routes (intra-area or interarea routes) will be automatically redistributed to OMP. Ans: A should be correct answer.
