IP routing in L3 capable switches

[kphelps]

Is L3 ip routing on by default in 3550s?  If so is the "ip routing" command visible in the config file?  If no - I assume that one would enable L3 routing with that config command.

In general terms are there any IOS devices where ip routing is enabled and one would not see the "ip routing" command in config.  I.E. if that command is not visible in the config could you assume there is no L3 capablity in that device?

Many thanks

Hi,

no, ip routing is not enabled by default on L3 switches like the 3550 and if it is you'll see the command in the config and

the command sh ip route will show you routes for connected subnets or static routes or any IGP learned routes.

But on routers as it is the default you won't see it in the config.

Regards.
