====== 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
