CCIEv5.ts.lab1.ticket 8

The ipv6 section of the solution is not incomplete. You have to change the ipv6 address of the virtual-template from ipv6 address autoconfig to ipv6 unnumbered GigabitEthernet1.1820.

The ticket requires us to get the followirng result but 2004:172:23:20::20  is not the address of g1.1920 (auto config) but instead of g1.1820 -

R19#traceroute 2001:122:1:1::20
Type escape sequence to abort.
