Diagnostics

This document describes the intended interpretation of MTRP diagnostic 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

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

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.

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.

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
