[j-nsp] IRB MAC Address Question

[Paul Stewart]

Hi there...

 

I'm trying to figure out what MAC address an IRB assumes?  In this case
IRB.61 interface....

 

  Logical interface irb.61 (Index 84) (SNMP ifIndex 187)

    Flags: SNMP-Traps 0x4004000 Encapsulation: ENET2

    Bandwidth: 10000mbps

    Routing Instance: default-switch Bridging Domain: vlan-61+61

    Input packets : 32942

    Output packets: 938

    Protocol inet, MTU: 1500

      Addresses, Flags: Is-Preferred Is-Primary

        Destination: xx.xx.xx/24, Local: xx.xx.xx.34, Broadcast:
xx.xx.xx.255

    Protocol inet6, MTU: 1500

      Flags: Is-Primary

      Addresses, Flags: Is-Default Is-Preferred Is-Primary

        Destination: xxxx:xxx:xxx::/64, Local: xxxx:xxx:xxx::34

      Addresses, Flags: Is-Preferred

        Destination: fe80::/64, Local: fe80::222:83ff:fe07:7ff0

    Protocol multiservice, MTU: 1500

unit 0 {

    family bridge {

        interface-mode trunk;

        vlan-id-list 61;

    }

}

 

bridge-domains {

    vlan-61 {

        domain-type bridge;

        vlan-id 61;

        routing-interface irb.61;

    }

}

 

We have some MAC filtering upstream from this switch for this particular
VLAN - the previous MAC was that of the subinterface itself before we
converted it to IRB.....

 

Hope this makes sense... thanks...
