3.8 Configure, verify, and troubleshoot IPv6 static routing

IPv6 static routing is the same as IPv4 the only difference is the structure of the IP addresses which use prefixes instead of netmasks.

For example here we create a static route to R3 through R2 and set the Administrative Distance to 1.

Router#conf t 
Enter configuration commands, one per line. End with CNTL/Z.
