Routers confirm a link is still
active.
Figure 2-6. Frame Relay Multilink Hellos
If the interface is continually sending requests to add a link instead of hellos,
the endpoint probably does not support MLFR. It is also possible that carrier
lines on either end of the link are configured for a different set of channels.
(See Figure 2-7.)
Figure 2-7. MLFR Link Does Not Go Up
Figure 2-8 shows a carrier line that was successfully added to a bundle.
