  • 1.  Two service providers one 2930M switch

    Posted Mar 07, 2021 07:49 AM
    Good day
    I have two sservice providers which needs to plug into one 2930M switch 
    Service provider one has internal interface 172.16.55.1/24 and my switch VLAN 55 - 172.16.55.10/24
    Service provider two has internal interface 172.19.55.1/24 and my switch VLAN 155 - 172.16.55.10/24
    I tried PBR but it doesnt work 
    I tried routing 172.16.55.0 0.0.0.0255 172.16.55.1
    I tried routing 172.19.55.0 0.0.0.0255 172.19.55.1
    Please help me with some ideas
    Thank you

    Hi Charl,

    What do you need to make ?

    ------------------------------
    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 you for replying allgoutte 
    I need for all traffic from VLAN 55 - 172.19.55.0/24 to go to gateway 172.16.55.1 (Provider one) and all traffic on VLAN 155 - 172.19.55.0/24 to go to gateway 172.19.55.1
    It is two different companies sharing one switch 
    My Core is Aruba 2930M
    Please advise on what i should do; traditionally I would have used Cisco layer 3 switch to do VRF but in this case I must use the existing Aruba 2930M

    Did you try:

    ip route 172.16.55.0/24 172.16.55.1
    ip route 172.19.55.0/24 172.19.55.1

    and remove 0.0.0.0/0 to def.gw?

    Hi,

    do you have a schema ? you have some other gateway on the network ? (you really need to route on 2930M ?)

    the VLAN 55 need to see the vlan 155 ?

    Why do you want to affect a IP Address on your core switch ?
    you need only to set on VLAN 55, the GW with 172.16.55.1 for device

    Thank you for your feedback
    Unfortunatly VLAN 55 and VLAN 155 should not see each other as it is a business requirement. They are two deffernt companies sharing one switch with their own internet through which they have to access their own services.
    so basically VLAN 55 Company 1 needs to access internet on their router with internal interface 172.16.55.1 and Company 2 needs to access internet on their router with internal interface 172.19.55.1

    Well,

    I don't get it right to what your requirements are, compared to the diagram which you have provided. However, i see this as very simple:

    My question is: Who is doing NAT here? If you have two independent routers (1 per each Company) then:

    Company 1: VLAN 55
    Configure interfaces in the switch with VLAN 55 as Access and place on the DHCP the default gateway to point at: 172.16.55.1
    Configure the interface on the router, which you connect to VLAN 55 on the switch, and give the interface the IP Address 172.16.55.1

    Company 2: VLAN144
    Configure interfaces in the switch with VLAN 155 as Access and place on the DHCP the default gateway to point at: 172.19.55.1
    Configure the interface on the router, which you connect to VLAN 155 on the switch, and give the interface the IP Address 172.19.55.1

    So, i would leave the switch as pure Layer-2 devices, dividing the companies traffic only by VLANs.
