Grading Checklist: Traffic From Specific Source Not Taking Expected Path

  • Reviewed the route-map configuration and identified the match/set clauses
  • Checked that the route-map is applied to the correct interface and direction
  • Identified that the ACL or match criteria do not correctly match the target traffic
  • Examined the ACL or prefix-list referenced in the match clause
  • Verified the specific mismatch (wrong source address, wrong ACL number, permit vs. deny)
  • Checked route-map hit counters to confirm zero matches
  • Verified the set next-hop is reachable and valid
  • Proposed fix: correct the ACL/match clause to properly match 10.100.0.0/24
  • Explained that PBR match uses ACL permit to match (not to filter)
  • Included verification steps (traceroute, route-map counters incrementing)
  • Mentioned that PBR does not apply to router-originated traffic by default
  • Discussed the relationship between PBR and the normal routing table (PBR takes precedence)
