Re: Frame-relay switch

Thanks Darby,

In my current lab, I am attempting to route all traffic through R3,
using one DLCI at the R1 connection, and two DLCI's at the R3/R4
connection. In essence it is a mesh, though physically a hub and spoke.
R3 being the hub. I also need to control traffic between R3 and R4, such
that traffic from R1 to R4 goes via one DLCI, while traffic from R3 to
R4 goes via the other DLCI.

regards Andy
