    |
    | I'm trying to run freevrrpd on a server with two interfaces for
    | redundancy. I want them both to act as one IP in a master/slave setup.
    | Here's the errors I'm getting:
    |

    |
    | Here's my config:
    |
    | [VRID]
    | serverid = 10
    | interface = fxp0
    | priority = 255
    | addr = a.b.c.131/26
    | password = test
    |
    | [VRID]
    | serverid = 10
    | interface = fxp1
    | priority = 254
    | addr = a.b.c.131/26
    | password = test
    |
    | And in rc.conf:
    |
    | ifconfig_fxp0="inet a.b.c.186 netmask 255.255.255.192"
    | ifconfig_fxp1="inet a.b.c.187 netmask 255.255.255.192"
    |
    | TIA,
    |
    | Bryce

    Ni Bryce,

    Try setting the mask on the VIP to /32 instead of /26. IIRC, an alias
    address must have a /32 mask, as the routing table already has an entry for
    a.b.c.128/26 (in your case), which is why it is rejecting the VIP address
    assignment.
