Re: ip classless

There is really no need to use this command these days. since it is the default behaviour. In the older days, the default behaviour was 'no ip classless' so you had to explicitly turn this on - nowadays, it's on by default.

Re: ip classless

Hi Carl,

As Paresh already explined that in new IOS codes it is enabled by default but to explain you what it does is something like this at times the router might receive packets destined for a subnet of a network that has no network default route.

To have the Cisco IOS software forward such packets to the best supernet route possible, use the ip classless global configuration command.

To read more about this have a look at this link

HTH, if yes please rate the post.
