VSX Protocol configuration on HP Aruba 8360

  • 1.  VSX Protocol configuration on HP Aruba 8360

    Hi there

    I have two HP Aruba-8360 and I configured VSX on both. As you can see in the topology diagram one is primary and other one is secondary.

    On Primary I have Multiple VLANs, Interface vlans and DHCP Pool for corresponding vlans. And on secondary using " VSX-SYNC '' I got vlans on my secondary switch but was unable to get SVI for corresponding vlans. 
    My question is :
    Is it essential that we have different ip addresses in SVI on both primary and secondary?. Like for example I have 

    On Primary HP Aruba-8360

    interface vlan 5
        vsx-sync active-gateways
        description BMS
        ip address 172.22.x.x/24
        active-gateway ip mac 00:00:00:00:00:05
        active-gateway ip 172.22.x.x
    interface vlan 6
        vsx-sync active-gateways
        description Metering
        ip address 172.22.x.x/24
        active-gateway ip mac 00:00:00:00:00:06
        active-gateway ip 172.22.x.x

    So On Secondary HP Aruba-8360

    Should I have different ip address for interface vlan 5 and 6. I know we can keep the active-gateway the same on both switches but I'm not sure about IP Address for SVI. 

    And how I can sync primary interface vlan 5 and 6 on secondary switch using VSX Protocol in HP-Aruba 8360.

    Was this post triple posted? I'm pretty much sure I answered it quite immediately once I saw it and then I saw an identical one answered by another Community member...then this one.

    Yes, you must have 3 IP addresses for the same SVI,
    • SVI IP address for the primary
    • SVI IP address for the secondary
    • active-gateway (virtual) IP address - shared
    The active-gateway MAC address is shared (same on both).

    For example on interface vlan 5:
    Primary: 
    interface vlan 5
        vsx-sync active-gateways
        description BMS
        ip address 172.22.16.2/24
        active-gateway ip mac 00:00:00:00:00:05
        active-gateway ip 172.22.16.1
    Secondary
    interface vlan 5
        description BMS
        ip address 172.22.16.3/24

    As you correctly have, vsx-sync will synchronize the active gateway configuration from primary to secondary.

    The reason you need these two IP addresses is because the routing plane on both devises is independent.
