[j-nsp] Trunking routed vlan interfaces on a Juniper mx960

[Dan Farrell]

This is how I do it... if this is not a recommended method, please let me know (PLEASE!) I currently configure around 90 L3 interfaces in this manner right now.

interfaces {
	ge-0/0/20 {
        description "physical port";
        unit 0 {
            family ethernet-switching {
                port-mode trunk;
                native-vlan-id 3007;
            }
        }
	}

	vlan {
       	 unit 98 {
        	    description "prov - vlan 98 - 8.0.0.0/30 - pri-switch - fa0/3";
        	    family inet {
       	         address 8.0.0.1/30;
       	     }
	  	}

		 unit 4070 {
            	    description "psc - vlan 4070 - 10.254.0.128/26";
                 family inet {
                	  address 10.254.0.129/26;
            	    }
        	}
      		  }

vlans {
	prov {
        description "prov - vlan 98 - 8.0.0.0/30 - pri-switch - fa0/3";
        vlan-id 98;
        interface {
            ge-0/0/20.0;
            ge-0/0/1.0;
        }
        l3-interface vlan.98;
    }

	psc {
        description "psc - vlan 4070 - 10.254.0.128/26";
        vlan-id 4070;
        interface {
            ge-0/0/20.0;
        }
        l3-interface vlan.4070;
    }


Thanks,


Dan
