You just need to get the link local address from the remote side of the
link, you should know what it is if you statically assigned it with the
link-local keyword, or else do a "show ipv6 int" on the remote interface
to get the automagically assigned ipv6 link local address. This is a
common recursion issue you'll run into on multipoint interfaces and ipv6.
Rack1R3(config-if)#do sh ipv6 in
Ethernet0/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::230:94FF:FEC4:9F01
frame-relay map ipv6 FE80::230:94FF:FEC4:9F01 302
