I will add new test case for IPV6.

For IPV4 address, following 2 commands are exactly same:
up ip rule add pref 32764 to 11.11.11.11 table 5000
up ip -4 rule add pref 32764 to 11.11.11.11 table 5000

But for IPV6 address, we always need add '-6' parameter:
up ip -6 rule add pref 32764 to 2603:10e2:0:2902::8 table 5000
