Hi !
CSCdt33911
It's also in versions 12.1(1)E, 12.1(2)E, 12.1(3)E, 12.1(4)E, 12.1(5)E
basically all we tested ;-)
Although if you don't use MPLS, you don't necessarily have problems - in
most of our test, we didn't see any problems during 'normal' routing but
you could see that CEF is not working because packets wich should be
label switched were just routed.
Cheers,
Chris
