  • 1.  ARUBA 8325 VSX and OSPF

    Posted Feb 04, 2021 10:50 AM
    Hi evryone!!!

    I have a question :

    I would like to set up OSPF Point to Point between my two VSX, I know how to set up the OSPF Point 2 point between a vsx and a Switch alone, but whit 2 vsx, where i configure the OSPF ?






    For my old configuration I confugure a @IP OSPF (in blue) on every interface, but with the vsx LAG where can i configure the OSPF IP?

    Hi Artnod

    you can configure a ip address on lag interface with Aruba CX

    ------------------------------
    PowerArubaSW : Powershell Module to use Aruba Switch API for Vlan, VlanPorts, LACP, LLDP...

    PowerArubaCP: Powershell Module to use ClearPass API (create NAD, Guest...)

    PowerArubaCX: Powershell Module to use ArubaCX API (get interface/vlan/ports info)..

    Thank for your return, but i need to be sure for my configuration.

    I need to configure a IP for my point to point on the interface lag, like this?

    On the vsx Serveur
    interface lag 12 multi-chassis
                          vsx-sync
                          no shut
                          no routing
                          vlan trunk allowed 200 (this is the vlan of my Server)
                          lacp mode active
                          ip address 10.0.2/31
                          ip ospf 1 area 0.0.0.0
                          no ip ospf passive
                          ip ospf cost 1000
                          ip ospf network Point-toPoint



      On the vsx Core
    interface lag 11 multi-chassis
                          vsx-sync
                          no shut
                          no routing
                          vlan trunk allowed all
                          lacp mode active
                          ip address 10.0.1/31
                          ip ospf 1 area 0.0.0.0
                          no ip ospf passive
                          ip ospf cost 1000
                          ip ospf network Point-toPoint

    You cannot have a Layer3 LAG and Layer 2 LAG  on same interface.

    Your options are

    1. Have a Layer 3 LAG with an IP address on it and its a routed port and then define your routing requirements here i.e OSPF in your case

    or

    2 . Have a Layer 2 LAG with an allowed VLAN on it.
    You would then need a VLAN defined which you then put your routing parameters on i.e OSPF in your case

    for example
    !
    interface lag 100 multi-chassis
    no shutdown
    no routing
    vlan access 100  <-----you can use a VLAN TRUNK ALLOWED and specify the vlan
    lacp mode active
    !
    interface vlan 100
    vsx active-forwarding
    ip address 10.100.100.1/30
    ip ospf 1 area 0.0.0.0
    no ip ospf passive
    !
    router ospf 1
    router-id 10.254.254.1
    passive-interface default
    area 0.0.0.0

    if i understand, i need to create a transit vlan for point-to-point like the vlan 2 and 3 on my schema, and i need to put th'is vlan on the lag.
    Can you tell me if my configuration is good or not? on the switch serveur, i have a vlan 200 for the differents server and on the Core I have three vlan user only.

    On the Serveur 1
    !

    Did you take a look on the VSX Best Practices that contains several examples.
    This may help you to determine as well if you need routed ports instead of VSX LAG+transit VLAN.

    I already read the best practice, I tried with configuration, when i show the interface is ok but the lag interface 3 is blocked





    And when i want to show the lacp interface, i have this LACP-BLOC

    When i see my conf :
     on core :
    !
    vlan 3
    vsx-sync
    description INTER-SITE TRANSITE VLAN

    !
    interface lag 3 multi-chassis
    no shutdown
    description INTER-SITE VSX LAG
    no routing
    vlan trunk native 1
    vlan trunk allowed 3,100,103-107
    lacp mode active
    spanning-tree bpdu-filter

    !
    interface 1/1/51
    no shutdown
    mtu 9198
    description INTER-SITE Link
    lag 3
    interface 1/1/54
    no shutdown
    mtu 9198
    description INTER-SITE Link
    lag 3

    !
    interface vlan 3
    ip mtu 9198
    vsx active-forwarding
    ip address 10.0.3.1/29
    ip ospf 1 area 0.0.0.0
    ip ospf cost 1000



    and same configuration on the 3 other Switch, just the IP of the interface vlan 3 change :
    - on core 2 :ip address 10.0.3.2/29
    ​- on srv 1:ip address 10.0.3.3/29
    - on srv 2 :ip address 10.0.3.4/29

    You need to fix the LACP-BLOCK,

    Do you have check the lldp neighbor ?

    Unless you need a VLAN trunk to that switch for transport more VLANS I Would use to /30 or /31, one for each connection to the VSX and use OSPF and ECMP.

    Ok i'm comeback for the new, i try a new conf and it's work!!!

    My problem is  the P2P between the vlan transit for my VSX.

    I made no ip ospf network point-to-point on every interface of my architecture and it's work!!

    Hi Artnod,

    We require a similar configuration.
    Could you please share the configuration that worked for you?

    Thanks
