Summary

This article describes the basic setup of Point-to-Point L2VPN with Juniper J-series routers.

Configuration

Consider network setup as ilustrated below:

L2circuit-juniper.png

We will be setting up the layer 2 connection between the CE and PE routers as well as the MPLS and L2VPN between PE routers. The layer 2 link between the CE and PE routers will be an Ethernet VLAN circuit.


Set up VLANs

CE1 and CE2 routers:

/interface vlan
  add vlan-id=600 name=vlan1 disabled=no interface=ether1

PE1 RouterOS: No configuration currently is needed, later we will bridge VPLS tunnel.

PE2 JunOS:

interfaces {
    fe-0/0/1 {
        vlan-tagging;
        encapsulation vlan-ccc;
        unit 1 {
            encapsulation vlan-ccc;
            vlan-id 600;
        }
    }
}

Set up IP connection, OSPF and LDP

PE1 (RouterOS):

/interface bridge 
  add name=loopback

/ip address
  add address=192.168.168.2/24 interface=ether3
  add address=10.255.11.31/32 interface=loopback

/routing ospf network
  add area=backbone disabled=no network=192.168.168.0/24
  add area=backbone disabled=no network=10.255.11.31/32

/mpls ldp
  set enabled=yes lsr-id=10.255.11.31 transport-address=10.255.11.31

/mpls ldp interface
  add interface=ether3

P (RouterOS):

/interface bridge 
  add name=loopback

/ip address
  add address=10.0.11.23/24 interface=ether1
  add address=192.168.168.1/24 interface=ether2
  add address=10.255.11.23/32 interface=loopback

/routing ospf network
  add area=backbone disabled=no network=10.0.11.0/24
  add area=backbone disabled=no network=192.168.168.0/24
  add area=backbone disabled=no network=10.255.11.23/32

/mpls ldp
  set enabled=yes lsr-id=10.255.11.23 transport-address=10.255.11.23

/mpls ldp interface
  add interface=ether1
  add interface=ether2

PE2 (JunOS):

interfaces {
    fe-0/0/0 {
        unit 0 {
            family inet {
                address 10.0.11.201/24;
            }
            family mpls;
        }
    }
    lo0 {
        unit 0 {
            family inet {
                address 10.255.11.201/32;
            }
        }
    }
}

protocols {
    mpls {
        interface fe-0/0/0.0;
        interface lo0.0;

    }

    ospf {
        export [ export-connected originate ];
        area 0.0.0.0 {
            interface fe-0/0/0.0;
            interface lo0.0 {
                passive;
            }
        }
    }
    ldp {
        egress-policy connected-only;
        transport-address 10.255.11.201;
        interface all;
    }
}

Finally we need to define policy options to advertise label binding for Loopback prefix:

policy-options {
    prefix-list loopback-prefix {
        10.255.11.201/32;
    }
    policy-statement connected-only {
        from {
            prefix-list loopback-prefix;
        }
        then accept;
    }
}

Set up L2VPN

PE1 RouterOS:

/interface vpls
  add cisco-style=yes cisco-style-id=5 name=junos-l2circuit pw-type=tagged-ethernet \
    remote-peer=10.255.11.201

PE2 Junos:

protocol {
    l2circuit {
        neighbor 10.255.11.31 {
            interface fe-0/0/1.1 {
                virtual-circuit-id 5;
            }
        }
    }
}
