Using the "show ip route" command. First, how is the output actually sorted? Also is there any way to sort the table so the host or network routes are in order from 126.96.36.199 to 255.255.255.255 for example? Yes you could drop this to excel and then sort from A to Z but you would think there is a way to do this in IOS. Specifically 12.4(25)T2.
I once tried a "show ip route | include x.x.x.x" on a 7206VXR with full routing and the poor router almost kissed me goodbye! (Don't try this at work! ). Although the previous incident I mentioned is not entirely the same procedure as IOS printing the routing table, may I ask if this unsorted output is done specifically for performance reasons?
Thanks for your reply. Sorry I didn't phrase my question very well in the first place. I am not asking about the details of tree (not because I am not interested, but I usually forget complex details and always have to look them up anyway :-). Since the internal representation of the routing table is different than a perfectly sorted list, could the sorted printing of the routing table cause delay in the "sh ip route" output or high CPU usage on the router or inconsistencies in the output or anything like that? I mean why the developers have chosen not to print it sorted in the first place? Or is there no issue and we could expect at some point in the future to see it sorted?
If your DE's manage to fix all the critical bugs, then I guess we could live with the routing table being printed even in reverse chronological order! I personally never minded about the order, because I find the "sh ip rou " a more useful troubleshooting command.

Not the exactly same information, but have you tried a show ip cef (if CEF is enabled)?
