Hi, I have a simulated IP FrameRelay lab at home. When using IPV4, I can ping from Site a to Site b and vice versa. As soon as I change to IPV6, I cannot. My lab is built using Multipoint Frame Relay. I have statically mapped the L3 IPV6 address of each end to the DLCI, the pvc's are active, frame-relay map command output says it is up but when I try to ping I am getting no reply. I have 2600 in the middle acting as a Frame-Relay switch but it is just running IOS 12.0(11), the other 2 routers are running 12.4T. Any ideas?
The link local addresses are significant across a link, but nowhere else. If you like, they are for use between a pair of routers. Link-local addresses are always host addresses, i.e. /128.
Being link-local, you can use the same address on several different links. In fact, if you try to ping the link-local address of a partner, say from R1 to fe80::2, the router will come back and say "OK, but on which interface?"
