RIP metric of 0 means it's a directly connected route.  Valid metrics are 
1 - 15, with 16 used as "dead".

Nanogers,

We are running RIP on one of our small cutomer routers and we are
receiving routes with RIP metric 0. Is this valid? I thought each RIP
router sends a metric of atleast 1, which is also what the RIP RFC
seems to suggest.

Has anyone ever come across such a scenario, i.e seeing RIP routes
with metric 0?

Thanks,
Kent
