Task 9.1 Link-local addresses reachability
I am not able to ping link-local address of any spoke from spoke unless I enable "ipv6 unicast-routing on hub router (R5).
Link-local address are not routable and should stay only on local segment/link. However in order to reach for example R2 from R1 using link-local address
fe80::2 packet will go in and out the same frame-relay multipoint interface s1/0 on R5. Unfortunately ONLY with "ipv6 unicast-routing" enabled on R5 ping is forwarded.
Verified on 3725 running 12.4(15)T7 on R5.
