Hi all, I have some questions about IGRP :
- In an update, IGRP distinguish Subnets, AS Networks and outside-AS networks, when I take some traces, I can see that there's the number of each category and then all routing entries but I don't understand how IGRP know if the routing entry is Subnet, AS or outside AS. Distinguishing AS routes (major net) or subnets is not important (applying interface mask and comparing major networks can do distinction), but how IGRP knows if the routing entry is candidate default ? - I can see in traces that IP addresses are coded with just 3 bytes, so I think I cannot use subnets > 24 bits ... isn't it ? - I can see different routing entry types, for example (traces done with NAI Sniffer Pro) : ROUTING ENTRY #1 IP Address = [172.16.1.0] ... ROUTING ENTRY #2 IP Address = [10.0.0.XX] ... what does the XX mean ??? I can see in hexa dump that's 00 - What is the utility of the hopcount ? preventing from loop like in RIP ? (so is the hop count incremented hop by hop ?) - I saw that Cisco implement trigger updates in IGRP, but on a Cisco 1603R with IOS 12.0(4)T, it don't seem to be implemented, when there's a change in topology, there's no trigger update. Does anyone experienced this problem ? - Does IGRP use a database like RIP ? or not ? Can I see the database like "show ip rip database" ? thanks a lot.
