Hello,
First of all, on a point to point interface, no layer 3 to 2 resolution is required hence no frame map statement is required (infact you will notice that it is rejected). This means that the whole dynamic routing issue with resolution to link local address does not exist with point to point interfaces.
For multipoint (which includes physical interfaces), you need to ensure at least one frame map statement to every dlci includes the broadcast keyword. Just like with IPv4, it is a replicated broadcast and not a true broadcast, hence it uses the broadcast key word next a dlci regardless of which layer 3 address is in the map statement to replicate the broadcast/multicast for the layer 3 type on that dlci.
What is important is that for dynamic routing protocols, make sure you have a frame map statement for the link-local and not just the global unicast since routing resolution points to the link-local address.
Best Regards
Enyi

Subject: Broadcast key word with IPV6 frame-relay MAPPING
Fellas,
I'm confused about using the broadcast key with IPV6 frame relay mapping.
Say on a point to point frame-relay connection between 2 routers running
IPV6. Where do I need the boardcast key word. Do I need it with link-local
address and DLCI mapping or I need it with global unicast address and DLCI
mapping ??????????
