Service-aware path visualization #3358
Description
When tracing a path between two nodes in lake, resolve via the correct topology for the selected traffic type: unicast uses algo 128 (tagged links only), multicast uses algo 0 (all links). Paths between the same pair may differ.
Milestone: RFC-18: Observability
RFC: #3288
Repo: lake
Size: Medium
Tests:
- Unicast path excludes untagged links
- Multicast path includes all links
- Paths between same node pair differ when untagged links exist on the route
