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)
