Route Convergence Monitoring and Diagnostics
Route Convergence Monitoring and Diagnostics (RCMD) is a mechanism to monitor OSPF and ISIS
convergence events, gather details about the SPF runs and time taken to provision routes and LDP labels
across all LCs on the router.
RCMD is a tool that collects and reports data related to routing convergence. Highlights of the RCMD
mechanism are:
• 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:
• 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.
