Please log in for more thread options I have a problem concerning 'IP CLASSLESS' on cisco routers I have quite a lot of vpn tunnels with IP CLASSLESS enabled on the router and some that it is not enabled. i have noticed that there are some application that i'm using that are not working fine when it's not enabled. i've tried to enable it on those routers but it doesn't seem to change anything. i typed 'IP CLASSLESS' and when i look in the running config it's nowhere for example: cisco 871w with IOS Version 12.4 = no IP CLASSLESS = not working ( but i don't seem to be able to enable it) cisco 851 with IOS Version 12.3 = IP CLASSLESS enabled = works fine any explanation? | ||||||||||||||||||||||||||||||||||

Please log in for more thread options There are numerous commands that do not show up in the configuration file when set to their default state. Furthermore, the default may change from one IOS release to another, as well as whether they show up when configured to their default state. The behavior of "Default Routing" is very much dependent on the setting of "IP Classless", and is likely the functional issue you have observed.

AFAIK these commands are a special case of what is displayed by show running-config; typically default commands are not displayed. Both of the commands "ip classless" and "no ip classless" will show up in output of sh running-config. At least this is the behavior with IOS 12.3 | ||||||||||||||||||||||||||||||||||
