    Hi, Im new to this so right now I am using VRRP in my network, I have already used the limit of 7 VRRP identifiers, one ID for one VLAN. I know that one VRRP ID can proctect up to 254 subnets. In my network I have about 10 VLANs that I want to protect, so my question is, Is this the right way to configure several VLANs in one VRRP ID?

    create vrrp vlan Vlan-1 vrid 1
    create vrrp vlan Vlan-2 vrid 1
    create vrrp vlan Vlan-3 vrid 1
    create vrrp vlan Vlan-4 vrid 1
    create vrrp vlan Vlan-5 vrid 1

    configure vrrp vlan vlan-1 vrid 1 priority 150
    configure vrrp vlan vlan-2 vrid 1 priority 150
    configure vrrp vlan vlan-3 vrid 1 priority 150
    configure vrrp vlan vlan-4 vrid 1 priority 150
    configure vrrp vlan vlan-5 vrid 1 priority 150

    configure vrrp vlan vlan-1 vrid 1 add 10.10.1.254
    configure vrrp vlan vlan-2 vrid 1 add 10.20.2.254
    configure vrrp vlan vlan-3 vrid 1 add 10.30.3.254
    configure vrrp vlan vlan-4 vrid 1 add 10.40.4.254
    configure vrrp vlan vlan-5 vrid 1 add 10.50.5.254

    enable vrrp vlan vlan-1 vrid 1
    enable vrrp vlan vlan-2 vrid 1
    enable vrrp vlan vlan-3 vrid 1
    enable vrrp vlan vlan-4 vrid 1
    enable vrrp vlan vlan-5 vrid 1

    By the way Im using two Black Diamond 8806
    And do I have to do this in both switches?
    Any Help is Aprecciated Thanks!!!

    Yes, It's correct way to configure vrrp.

    You have to configure the same command on both the switch, Backup switch don't require the priority command .

    Hey Erick

    As a side not the VRID is just to distinguish which routers will be paired for the VRRP service. If you only have 2 then use the same VRID. If you have a situation where you have 4 routers and you want 1 &@ to be VRRP pair for certain subnets and 3 &$ to be paired for other subnets then you would use the VRIDs to tell the routers who they are paired with.

    Hope that helps
