VRRP fabric routing, secondary IPs and IPv6?

    Now that fabric routing has caught my attention, I have a couple of questions (for 16.2+, I don't think I can run 21+ on my BD8806)

    1) Does it work with secondary IP addresses (config snippet below)?
    configure vlan FOO ipaddress 10.0.0.252/24
    configure vlan FOO add secondary ipaddress 192.168.0.252/24
    create vrrp vlan FOO vrid 1
    configure vrrp vlan FOO vrid 1 add 10.0.0.254
    configure vrrp vlan FOO vrid 1 add 192.168.0.254
    [/code]2) Does it work with IPv6 addresses?

    3) The examples show fabric routing setup with different priorities for the two routers/switches involved. What's the advantage of doing that? Is it just to define the master for direct pings?

    Thank you (and Happy New Year!)

    Frank,

    I don't see any reason why a secondary IPv4 or IPv6 wouldn't work. Different priorities just forces the master to be on one or the other instead of relying on the IP's. As a FYI the VRRP master is still responsible for answering all ARPs.

    Hi Frank,

    Yes, my customers use the secondary IP address and IPv6 in VRRP without any problem.
