RE: IPV6 over Frame Relay [7:139002]

Hi,

Thanks for your input.

Oddly enough, I did not enable IP6 routing on one of the spokes.

I enabled this and everything is now working, however what I don't fully
understand is the following

R1 is the hub. R2 and R3 are the spokes. I forgot to enable IPV6 routing on
R3. So I understand why R2 and R3 couldn't ping each other, but how was R3
able to ping R1 and vice-versa if R3 did not have IPV6 routing enabled?

Cheers

Sunny

my friend, you have only configured link local address and ipv4 address on
interfaces, you also need to configure and map ipv6 global unique address on
interfaces.
you don't need ipv4 address here, if you configure for any other purpose,
than that's fine.

Hi Guys,

I have R1 as the hub and R2 & R3 as the spoke over frame relay.

I can get all routers to ping each other on their IPV4 addresses. However,
over IPV6, the spokes can ping the hub but can't ping each other. The hub
can ping both spokes.

Am I missing something here?

Doing a show frame relay map shows all the mappings as active on all
routers.
