Ah, Thanks for clearing that up.

You need the broadcast statement per protocol per DLCI once. It doesn't
matter on which IPv6 address you put it.

Whilst we're on the subject I wonder if someone can clear something up
for me.

On some practice labs I've seen the broadcast statement on the IPV6
address and not the link local
and
some other labs I've seen the broadcast statement on the link local
address and not the physycial interface address.

Could somebody clear that up for me please which is the correct
configuration.

Thanks,

Simon.

I think you have to also map the link-local addresses with frame-relay
map.

Best regards,

Subject: Issue with RIPng over Frame Relay NBMA

Hi Group,

I'm facing an issue running RIPng over frame relay NBMA. Any help is
welcome. My config as follows:

R6 

--
ipv6 unicast-routing
!
interface Serial0/0/0
no ip address
encapsulation frame-relay
ipv6 address 2001:1:1:26::6/64
ipv6 rip big enable
frame-relay map ipv6 2001:1:1:26::2 601 broadcast  no frame-relay
inverse-arp !
ipv6 router rip big

R2
--
interface Loopback1
no ip address
ipv6 address 2000:1:2:2::2/64
ipv6 rip big enable
!
interface Serial0/0/0
no ip address
encapsulation frame-relay
ipv6 address 2001:1:1:26::2/64
ipv6 rip big enable
frame-relay map ipv6 2001:1:1:26::6 106 broadcast !
ipv6 router rip big

Verification:
-------------
R2#sh ipv int s 0/0/0
Serial0/0/0 is up, line protocol is up
  IPv6 is enabled, link-local address is FE80::21B:54FF:FECE:2072
  Global unicast address(es):
    2001:1:1:26::2, subnet is 2001:1:1:26::/64

R6#pi FE80::21B:54FF:FECE:2072
Output Interface: serial0/0/0
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FE80::21B:54FF:FECE:2072, timeout is 2
seconds:

R6#pi 2001:1:1:26::2

Success rate is 100 percent (5/5), round-trip min/avg/max = 56/56/56 ms

R6#sh ipv ro ri

     via FE80::21B:54FF:FECE:2072, Serial0/0/0

(1) I'm not able to ping to R2's link-local address from R6 but can ping
its global unicast address.
(2) R6 learns R2's loopback1 subnet address via RIP but can't ping R2's
loopback1 address.
(3) I notice the next-hop address of the RIP route is R2's link-local
address. I guess the reason why R6 can't ping R2's loopback1 has to do
with the issue of not being able to ping R2's link-local address.
(4) I have no issue if I re-configured the frame relay to p2p
subinterfaces.

Did I miss anything in my config? Reloading both routers doesn't help.
Please advise.

Thank you.

B.Rgds,
Lim TS
