Could someone kindly provide a skeleton
ifcfg-eth0:[X] for creating an alias with a IPv6 address and no IPv4 address?
Or, alternatively, what's the IPv6 equivalent of this:
DEVICE=eth0:1 ONBOOT=yes BOOTPROTO=static IPADDR=18.104.22.168 NETMASK=255.255.255.0
Or does this not even make sense in IPv6 space?
I know that I can use, for example:
But then do I need to specify that there is no IPv4 address associated with this alias? If so, how? And do I need to also specify the
IPV6_DEFAULTGW? Or can it piggyback on the eth0 (unaliased) gateway, which is specified, like with IPv4 aliases?
Answered my own question!
The easiest way to accomplish this seems to be not to create an alias as with IPV4, but to specify, for example,
IPV6ADDR_SECONDARIES=2600:4200::6900:6666:dead:beef on the script for the base interface, e.g.
