Understand How Network Paths Are Changing
RouteMon provides network path analysis, BGP path monitoring and AS path visibility to help network teams understand path changes affecting connectivity and service performance. Investigate how routes move across the network and identify path behaviour that requires attention.
A healthy session does not always meana healthy path
Connectivity may remain available while the route used to reach a destination changes significantly.
A path change can affect latency, traffic distribution, reachability, service performance and upstream connectivity.
RouteMon helps teams investigate these changes with greater path visibility.
BGP, AS-pathand reachability context
Understand how routes change across network paths and whether connectivity conditions changed with them.
- Evidence 01
BGP path changes
Changing paths and transitions across monitored routes.
- Evidence 02
Alternate routes
Alternate routing paths associated with changing connectivity.
- Evidence 03
Prefix and peer context
Prefix-specific and peer-specific path behaviour.
- Evidence 04
AS-path context
Path-length changes, upstream changes and unexpected AS transitions.
- Evidence 05
Reachability context
Reachability conditions associated with a path change.
Compare the routebehind the connection
Combine path monitoring, AS-path analysis and reachability evidence during connectivity investigation.
- 01Step
Identify the destination
Focus on the prefix or service whose connectivity changed.
- 02Step
Compare BGP paths
Review path transitions and alternate route usage.
- 03Step
Analyze the AS path
Check path length, upstream changes and unexpected AS transitions.
- 04Step
Review reachability
Determine whether the path change coincided with changed connectivity conditions.
Why PathInvestigation matters
- Understand where routing changed
- Investigate performance degradation
- Analyze alternate path usage
- Improve BGP troubleshooting
- Identify path-related connectivity issues
