(I use boson netsim to simulate the lab)
There are two router in this lab,router P1R1 and router P1R2,they are both configured using router protocol of ipv4 ospf and ipv6 ospf version 3.When I traceroute the ipv6 address of interface in P1R2 through P1R1,the path of traceroute show ipv4 path,is this normal or something I didn't get it.
(the show running-configuration in P1R1)

------------------------------------------------------
when I traceroute the loopback0 ipv6 address of P1R2 the result is below:
P1R1#traceroute 1:1:2:2::2
"Type escape sequence to abort."
Tracing the route to 1:1:2:2::2
1 10.1.0.2 20 msec 16 msec *
--------------------------------------------------------
so why the result of color blue is ipv4 address of P1R2's serial0 rather than it's ipv6 address
