virtual routers vrrp

    Hello together,

    I have a vrrp instance and the vr-default router.

    Know I will create a separate virtual router. How must I configure the vrrp?

    Can I use the same vrid? What is best practice?

    Cheers,
    Alexander

    Are you sure you need a different VR, or are you trying to get another virtual IP in the same vlan?

    You can use the same vrid as long as they are on different broadcast domains.

    Below is a simple config of what you are asking for. If you tell us what your trying to accomplish we might have a better option.

    [VRRP1 Switch]--p1----------p1--[VRRP2 Switch]

    #VRRP1 Switch

    #
    # Module vlan configuration.
    #
    configure vlan default delete ports all
    configure vr VR-Default delete ports all
    create vr "vrtest"
    create vlan "testvrrp" vr vrtest
    configure vlan testvrrp tag 100
    configure vlan Default add ports 1 untagged
    configure vlan testvrrp add ports 1 tagged
    configure vlan Default ipaddress 1.1.1.2 255.255.255.0
    configure vlan testvrrp ipaddress 2.2.2.2 255.255.255.0

    #
    # Module vrrp configuration.
    #
    create vrrp vlan Default vrid 1
    configure vrrp vlan Default vrid 1 priority 101
    create vrrp vlan testvrrp vrid 1
    configure vrrp vlan testvrrp vrid 1 priority 101
    configure vrrp vlan Default vrid 1 add 1.1.1.1
    configure vrrp vlan testvrrp vrid 1 add 2.2.2.1
    enable vrrp vlan Default vrid 1
    enable vrrp vlan testvrrp vrid 1

    VRRP2 Switch

    #
    # Module vlan configuration.
    #
    configure vlan default delete ports all
    configure vr VR-Default delete ports all
    create vr "vrtest"
    create vlan "testvrrp" vr vrtest
    configure vlan testvrrp tag 100
    configure vlan Default add ports 1 untagged
    configure vlan testvrrp add ports 1 tagged
    configure vlan Default ipaddress 1.1.1.3 255.255.255.0
    configure vlan testvrrp ipaddress 2.2.2.3 255.255.255.0

    #
    # Module vrrp configuration.
    #
    create vrrp vlan Default vrid 1
    configure vrrp vlan Default vrid 1 priority 50
    create vrrp vlan testvrrp vrid 1
    configure vrrp vlan testvrrp vrid 1 priority 50
    configure vrrp vlan Default vrid 1 add 1.1.1.1
    configure vrrp vlan testvrrp vrid 1 add 2.2.2.1
    enable vrrp vlan Default vrid 1
    enable vrrp vlan testvrrp vrid 1

    [/code]

    Thanks Stephen for your response.

    Yes I need a separate VR, because VoIP traffic must be separated from the other network (It’s a company rule).

    I try your solution with the 2 virtual routers and vrid 1.

    Thanks,
    Alexander

    You can do this with vlans. But if a VR is required by policy, it's required.
