  • 1.  Routing through MPLS Network - VRF?

    Hi,

     

    After a user has entered a network via L2TP and PPP, am I right in thinking that the best method of getting that user across an MPLS backbone ISP is via VRF's? If it is then could someone please show me an example of this?

     

    Thanks

    Hi Clive,

     

    All you need is to create the loopback and address-assignment under the VRF.

     

    You can use radius-attribute “ERX-Virtual-Router-Name := "TEST" or you can use predefined variable.

     

    LNS# show dynamic-profiles TEST

    predefined-variable-defaults {

        routing-instances TEST;

    }

     

    LNS# dynamic-profiles TEST

    routing-instances {

        "$junos-routing-instance" {

            interface "$junos-interface-name";

        }

    }

     

    LNS# show routing-instances TEST   

    instance-type vrf;

    interface lo0.4;

    vrf-target target:X:X;

    access {

        address-assignment {

            pool LAB {

                family inet {

                    network 10.0.0.0/22;

               }

            }

        }

    }
