Gustavo -

Here is the routes at R4....

The ping running, while debug was on at the R4 did not produce any
output or errors. However, you gave me an idea to try a traceroute on R1
to the loop. Here is the output. It appears that it gets to R3, but
then gets lost.

R1#traceroute ipv6 fec0::104:1

Type escape sequence to abort.

Can you show the ipv6 routing table of R4? And do a deb ipv6 packet
while you are pinging from R1. If R4 does not have a route to R1 serial,
it would not know how to reply to it.

I think that your redistribution is being done one way only FRAME-34 to
FRAME-123, although I think you have it well configured.

Can you also post sh ipv6 protocols?

Thanks for the response. You are seeing the problem that I am
seeing....I see the route to it, but cannot ping it from R1. I CAN get
a good ping response to that 604 loopback at R3. I turned on the debug
routing and repeated the process and it does not give me any
encapsulation failures. R4 only has the single serial interface.

Hi Dave, not sure I understand your problem, as you posted R1 ipv6 RIB
with
R FEC0::104:0/126 [120/3]
     via FE80::3, Serial0/0.123

You are not able to ping the R4 Loopback? Does it show encapsulation
failed when deb ipv6 packet?
Is R1 serial interface on R4's ipv6 RIB?

Do you have any other interface on IPV6 on R1?

Here is an issue that I am having with IPv6 redistribution.....I have 4
routers set up on two frame networks......

R1------------------R3(loop603------------------------R4 (loop604)
    \------------R2(loop602)

I can see all the routes at R1, except the loop604 at R4 (however, I see
the route to it both in the RIB and rip database. I am redistributing
the route into rip at R4, and redistributing at R3 (understanding that
the loopback must still be redistributed if it is connected directly to
the router (under IPv6). I also tried to add the R4 directly into the
rip process as an internal route, but it still cannot be reached by R1.
At first, I thought this to be a split horizon issue (in rip), but when
it was turned off at R1, the issue continues to exist. Here are the
configs.....any direction would be appreciated......
