IPv6 over Frame Relay and OSPF

When you configure multi-point Frame Relay for IPv6, to make the OSPF working for the interface, you need to manually map the link-local address to dlci.

R1 (2001::1/64, FE80::1 ) ------ R2 (2001::2/64, FE80::2)

R1 configuration:
interface serial 0
encapsulation frame-relay
ipv6 address 2001::1/64
ipv6 address FE80::1 link-local
frame map ipv6 2001::2 102 broadcast
frame map ipv6 FE80::2 102 broadcast
ipv6 ospf 1 area 0

R2 configuration:
interface serial 0
encapsulation frame-relay
ipv6 address 2001::2/64
ipv6 address FE80::2 link-local
frame map ipv6 2001::1 201 broadcast
frame map ipv6 FE80::1 201 broadcast
ipv6 ospf 1 area 0
