Hi lbemont,
by adding another address to the ifcfg file you’re not adding a virtual interface, but a secondary IP address to the interface.
From /etc/sysconfig/network/ifcfg.template:
[QUOTE] # For multiple addresses use this variable multiple times and extend them with
different suffixes. For example IPADDR_1=, IPADDR_2=. See section 'Multiple
addresses’ in manpage ifcfg).[/QUOTE]
So your syntax of using the suffix “_V1” should work. On the other hand, individual “up/down” of that IP address will not work.
To see the configure secondary IP address, use “ip addr list bond0”.

Jens
