Performs network discovery and routing information gathering through Cisco's Enhanced Interior Gateway Routing Protocol (EIGRP).
The script works by sending an EIGRP Hello packet with the specified Autonomous System value to the 220.127.116.11 multicast address and listening for EIGRP Update packets. The script then parses the update responses for routing information.
If no A.S value was provided by the user, the script will listen for multicast Hello packets to grab an A.S value. If no interface was provided as a script argument or through the -e option, the script will send packets and listen through all valid ethernet interfaces simultaneously.
the K metrics. Defaults to
Autonomous System value to announce on. If not set, the script will listen for announcements on 18.104.22.168 to grab an A.S value.
Interface to send on (overrides -e)
Max amount of time to listen for A.S announcements and updates. Defaults to
- max-newtargets, newtargets
See the documentation for the target library.
