Inverse-ARP not working with IPv6

[borek]

I have FR network with IPv6 addressing. When I use static mapping of IPv6 addresses, I can ping across the network OK; when I try to use InARP, it doesn't seem to work (yes, I know I cannot ping between spokes without static map). What can be wrong?

!--- R1

interface Serial6/7:0.2 multipoint

ipv6 address FEC0:0:0:4::/64 eui-64

frame-relay interface-dlci 144

frame-relay interface-dlci 145

!--- R4

interface Serial0/0/0:0

no ip address

encapsulation frame-relay

ipv6 address FEC0:0:0:4::/64 eui-64

frame-relay interface-dlci 104

R4#sh ipv6 interface s0/0/0:0 | inc FEC0

FEC0::4:218:73FF:FE1D:52C8, subnet is FEC0:0:0:4::/64 [EUI]

R1#ping FEC0::4:218:73FF:FE1D:52C8

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to FEC0::4:218:73FF:FE1D:52C8, timeout is 2 seconds:

.....

Success rate is 0 percent (0/5)

R1#sh frame-relay map int se6/7:0.2

I have found this document: http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t2/ipv6/ftipv6c.htm

It's pretty old (2003), so I am not sure whether it is valid. In it they write:

QUOTE BEGINS

In IPv4, the Inverse Address Resolution Protocol (Inverse ARP) is used to dynamically map the network-layer address of a node at the far end of a PVC to that PVC. Refer to the "Configuring ATM" and "Configuring Frame Relay" chapters of the Release 12.2, Cisco IOS Wide-Area Networking Configuration Guide publication for information on configuring Inverse ARP. In IPv6, Inverse Neighbor Discovery is used to dynamically map the global IPv6 address of a node at the far end of a PVC to that PVC.

QUOTE ENDS

Searching "Inverse Neighbor Discovery" doesn't yield any useful information though.

So I still have no definite answer about IPv6 inverse ARP.
