====== Diagnostics ======

===== 1. Purpose =====

This document describes the intended interpretation of MTRP diagnostic output.

===== 2. Summary Output =====

The summary output SHOULD provide a concise view of current router state, including:

  * device identifier
  * local node identifier
  * network identifier
  * address state
  * router state
  * registered path count
  * active neighbor count
  * active route count
  * transport capabilities
  * security capabilities

===== 3. Neighbor Summary =====

The neighbor summary describes directly reachable peers.

This output SHOULD be used to confirm:

  * direct neighbor discovery
  * direct-link metric values
  * aging and expiry behavior
  * capability and security visibility

===== 4. Route Summary =====

The route summary describes learned forwarding candidates.

The route summary MUST NOT be interpreted as a one-route-per-destination table.

Multiple entries for the same destination MAY be present and are normal when multiple next-hop candidates exist.

===== 5. Preferred Route Summary =====

The preferred route summary describes forwarding choices actually selected during send-time route resolution.

This table MAY remain empty if forwarding-table resolution has not yet been required.

===== 6. Interpretation Guidance =====

If active routes are present while preferred routes remain absent, that usually indicates:

  * route learning is functioning
  * forwarding candidates exist
  * direct-neighbor resolution has been sufficient so far
