FR Mapping confusion in IPV6

Unanswered Question
Jun 1st, 2009

Hi, I have configured IPV6 on Frame Relay. I am confused where to use "Broadcast" keyword in FR mapping. I mean should I use this in "Link-Local" address or Global Unicast address. Please help.

I have this problem too.

1. if I use "Broadcast" on Global unicast interface IP and removing on Link-Local, I am still getting all updates.

2. In both cases, I am seeing Next hop as Local link for OSPF update.

Any idea for both queries, why this is happening ?

Hello Rupesh,

this may come from the OSPF network type that influences if multicast are used or not.

sh ipv6 ospf int typex/y

or post the config

2) this is correct: OSPFv3 and EIGRPv6 exchange routing information using link local addresses so it is also reasonable to see the link local as the next-hop ipv6 address

Hope to help
