Nope. IPv6 pings are sourced from the unicast address on the
interface. The LL address comes into play when using routing protocols
(as stated in my original answer).
Rack1R1#conf t
Rack1R1(config-if)#int s1/0
Rack1R1(config-if)#ipv6 add 2000::1/64
Rack1R1(config-if)#frame map ipv6 2000::3 113
Rack1R1#deb ipv6 pack
IPv6 unicast packet debugging is on
Rack1R1#p 2000::3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2000::3, timeout is 2 seconds:

Success rate is 100 percent (5/5), round-trip min/avg/max = 8/16/40 ms
