Re: VRF TO GLOBAL PROBLEM

Hi Marko,

That's because in your example you needed reachability only between
the router's loopbacks. Let's say that R2-R6 10.0.26.0/24 is in global
and R2-R5 10.0.25.0/24 is into a VRF and you need to have reachability
between these two subnets. Can you give an example routing between
these two without having to use R4 ?

Regards.
