•
Lightweight and always-on using route flow markers across routing components (all nodes & MC).
•
Tracks most convergence events and all routes affected by them.
•
Provides within-router view with statistics and time-lines on per convergence event basis.
•
Measurements against time-line/SLA and triggers specified EEM actions on excess.
•
'On the router' reports via CLI/XML interface.
•
Each RCMD enabled router provides a digest of convergence data.
The events that are monitored and reported by RCMD are:
•
OSPF and IS-IS SPF events (default VRF only).
•
Add/delete of specific external or inter-area/level prefixes.
•
IGP flooding propagation delays for LSA/LSP changes.
RCMD runs in two modes:
• Monitoring—detecting events and measuring convergence.
• Diagnostics—additional (debug) information collection for 'abnormal' events.
