Hi Ryan,
I think secondary ip address issue will only make the whole lab setup get
more complex, it would be simpler if you can try again after you remove all
secondary ip addresses from all interfaces (router, server and client).
You can verify your configuration is good or not without secondary ip
address issue.
I cannot find anything wrong from your configuration unless you forgot to
put "ip pim dense-mode" on the link between R1 and R2.
Cheers~
Jacky
