Re: MPLS and OSPF Area 0 Hierarchy

I hear some lab testing coming up ... ;-)

Team - I am not trying to state the obvious here ... but ... this is a must
lab test for the v4 lab. If you have not already done so, try this and then
use the show commands ...

Cool stuff. I had read this before, but until I actually labbed it, it did
not make as much sense.

A suggestion would be to lab this and then post the quirky behavior you
find!

HTH,
