I want to thank you for your time. I had to modify the command you provided as if gave an error (inet.0 vs inet6.0) . The biggest thing is learning how all the various route tables are used and shared with the system.
set routing-options rib-groups inet0-inet63 import-rib inet6.0
set routing-options rib-groups inet0-inet63 import-rib inet6.3
set routing-options interface-routes rib-group inet6 inet0-inet63
set routing-options rib inet6.3 static route ::ffff:10.229.21.1/128 next-hop ::ffff:10.220.21.2
set routing-options rib inet6.3 static route ::ffff:10.229.21.1/128 next-hop ::ffff:10.220.21.6

I was able to ping from the PE to a loopback on the end device and it works.
