RE: IPv6 OSPFv3 neighbors over Frame-relay PVC

You don't have ipv6 ospf enabled under the serial interfaces for one.

Also, you only need the ipv6 neighbor command under the multipoint interface. With that said, there is something else you need to do under the physical interface of R5 to make sure OSPF can exchange ipv6 routes. Think what you would do when configuring ipv4!

HTH,
Jeff

Hi Group,

I've troubles in setting up neighborship between two routers over FR PVC.
The setup is as follows:

R2 using a multipoint subiface:

interface Serial0/1/0.100 multipoint
 ip address 192.168.66.2 255.255.255.0
 ipv6 address 2001::1/64
 ipv6 enable
 frame-relay map ipv6 2001::2 105
 frame-relay map ipv6 FE80::208:A3FF:FE2B:BF00 105
 frame-relay map ip 192.168.66.2 105
 frame-relay map ip 192.168.66.5 105 broadcast

R5 is using a physical iface:

interface Serial0/0
 ip address 192.168.66.5 255.255.255.0
 encapsulation frame-relay
 ipv6 address 2001::2/64
 ipv6 enable
 clock rate 64000
 frame-relay map ipv6 FE80::215:C6FF:FE78:6A98 501
 frame-relay map ipv6 2001::1 501
 frame-relay map ip 192.168.66.2 501 broadcast
 frame-relay map ip 192.168.66.5 501
 no frame-relay inverse-arp

connectivity using IPv4 and IPv6 global aggregatable address works (FR
cloud's OK)

Now, trying to establish OSPF neighbors using the link-local addresses of
the remote device:

R2:

ipv6 ospf neighbor FE80::208:A3FF:FE2B:BF00

R5:
ipv6 ospf neighbor FE80::215:C6FF:FE78:6A98

nothing happens. The link local addresses are the correct ones.
When tried to ping one of them from the remote device (for example from R5
to ping R2's link-local address) the routers asks me to enter an outgoing
interface:

R5#ping FE80::215:C6FF:FE78:6A98
Output Interface: serial0/0
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FE80::215:C6FF:FE78:6A98, timeout is 2
seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 56/57/60 ms

Any quidelines on establishing OSPF over NBMA neighbors appreciated! Do I
need to enter static ipv6 routes for the link-local addresses? Can't test
that as R2 doesn't allow me to do that, as opposed to R5 totally happy with
that.
Is there a cleaner way to configure that?
