3.2.1 Routing Monitoring Tool Set
Description
The RATool set (The Routing Arbiter project tool set, www.merit.edu) is a set of applications allowing the analysis of the real Internet routing tables (about 51 000 entries now) and compare them with the registered routing policies, evaluation of the different routing possibilities in the case of the lines outgages, checking the current routing, monitoring of the routing updates without massive involvement of router processor etc. The tool set runs on several platforms, the most used one is the SUN WS. The available applications are:
RS - Route Server, BGP peering deamon, routing stability monitoring
Rtconfig - Router configuration - creates router configurations from registered policies
roe - Route Object Editor - detects discrepancies between routing table and registered policies
aoe - Autonomous system Object Editor - displays and edits AS objects
prpath - enumerates a list of paths between two ASes
prcheck - performs syntactic and semantics check of registered objects
peval - low level policy evaluation tool, used to write the router configuration generators
CIDRadvisor - uses the registered policies and suggests aggregations
pmatch - lists all neigbours exporting or importing the specified route
prtraceroute - compares the result of a traceroute with the registered policies
Phases
- gain experience with configuring and operating the RATools
- evaluate the performance and usefulnes of the RATools
- definitions and plans for the development of the monitoring tools suitable for our purposes
- planning of the possible application in the production network
Goal
Create a tool for the operational BGP routing stability monitoring, the routing tables and registered policies checking and monitoring
Network infrastructure required
1) Test workstation/s with the appropriate software
2) BGP peering
