The EIGRP metric checker was designed to verify the EIGRP attributes of an IP route. This script will telnet/ssh into a list of routers and perform a “show ip route x.x.x.x” for a list of IP subnets. For each subnet, the actual EIGRP attributes of the route are extracted and compared against the expected attributes, which are predefined in an input file. Within a few seconds you can tell if any of your key network routing information has changed from its expected behavior. The EIGRP Attributes checked by the script are:
- Next Hop
- Administrative Distance
- Metric
- Delay
- Hop Count
- Route Tag
