Switching

Dear All , Im currently running a trunking connection between my cisco me3400 and a juniper mx960 using the following lines on juniper side.

trunk1 {
    description "trunking1 connection";
    vlan­tagging;
    unit 2 {
        vlan­id 2;                      
        family inet {
            address 20.0.0.254/32;
        }
    }
    unit 3 {
        vlan­id 3;
        family inet {
            address 30.0.0.254/32;
        }
    }
    unit 4 {
        vlan­id 4;
        family inet {
            address 40.0.0.254/24;
        }
   

Those ips , (20.0.0.254,30.0.0.254 and 40.0.0.254) are used as gws on the cisco connected devices.

Now I need to duplicate the configuration  adding a second trunk interface.

My question is, how should i create and configure the second trunk interface and bind it the gws ips confugured on the first trunk so new connected devices can use the same gws ips.

On IOS it can be  achieved creating the vlans and assign the gws ips on the vlan interfaces (not on the phisical inteface) and then assign the phisic ports to those vlans but it is not the same on junos.

I will add an scheme to be more explicit.

Any ideas  ?

btw , juniper mx960 doesnot allow "ethernet switching" family configuration.

Leo.

IRB (integrated routing and bridging) could be a solution ?

 use IRB, wich is equivlent of doing SVIs on Cisco
