You configure a 6to4 router, and try to communicate from system A to system B. The interfaces of
the source and destination systems are shown in the exhibit. Your ping:
systemA# ping -s fe80::203:baff:fe02:7aa5
yields:
ICMPv6 Address Unreachable from gateway 2002:8193:c9f::1
for icmp6 from 2002:8193:c9f::1 to fe80::203:baff:fe02:7aa5

A.
You did not add a default route for the IPv6 traffic.
B.
You can NOT reach the system on the local link address.
C.
You do not have a route to gateway 2002:8193:c9f::1.
