Zhen Cai,
I had to do a lot of routing table comparisons a while back and I used MS
Excel and MS Access to help with the compare. It has been a while, so I'd
find someone who knows basic Access if this doesn't make sense.
Here it goes:
1. Capture the routing tables in a text file.
2. Import the routes into excel.
3. Sort the list to help you get rid of unneeded lines (non-routes or majo
r
networks)
4. Import the excel spreadsheet into an Access table.
5. After you get a couple of tables in Access, you can run a "compare"
query, either matches or non-matches.
If you are methodical (import the tables exactly the same way each time), it
works and it's not too difficult. If you don't want to use a database query
tool like Access, you can use a highlighter:)

Subject: weird thought?
Hi,
When comparing two(or more) router's routing tables, I found it's very
boring if there are hundreds or even thousands routes. Is there some kind of
software that can tell me the difference between two routing tables? I'm not
talking about the distance or metric difference, but route difference...
Thanks a lot.
Zhen Cai
