AFAIK, before you can enable policy routing, you must configure one of these commands in the global configuration mode, and then the configuration must be written and the switch reloaded:
sdm prefer extended-match
sdm prefer access extended-match
sdm prefer routing extended-match
and comapare with latest IOS
so entering the "sdm prefer" -command wont help since the "set ip default" and "set ip next-hop" isnt supported?
What do they mean with this page:
where the commands are included in rhe example for C3550?
Just to answer your question about the page you posted, the Cat3550 IOS version in that
example is 12.1(19)EA1a, which already supports the command "set ip next-hop".
It is documented here:
The command "set ip default next-hop" is still unsupported up to the latest IOS version.
As Milan had mentioned, please compare the old IOS releases with the new ones to check any new features or solved caveats. I think it's time to upgrade your IOS.
