[j-nsp] l2vpn problem

We are starting to work on migrating many layer2 LAN connections over to our
MPLS environment.   I did a lab on l2vpn and it worked fine - trying it now
as a test on a production network and it's not working ;)

 

A pair of MX80's directly connected to one another - each MX80 has a trunked
Ethernet port connected to a notebook computer for testing (each notebook
supports dot1q VLAN and the proper VLAN is assigned).

 

Trying to figure out why this won't work and pretty sure it's config related
or my lack of understanding on something I thought I understood ;)

 

Between the MX80's is iBGP and LSP's established (remote end example):

Router #1 is xx.xx.100.71 for loopback

Router #2 is xx.xx.100.72 for loopback

 

RSVP/LSP is fully established and appears operational.

 

I keep getting "local site signaled down" status on the l2vpn:

 

paul at dis1.millbrook1> show l2vpn connections

Instance: customer-1

  Local site: dis1.millbrook1 (1)

    connection-site           Type  St     Time last up          # Up trans

    2                         rmt   LD

 

Configuration on router #1 looks like this:

 

interfaces {

    ge-1/3/5 {

        description TEST_l2vpn;

        vlan-tagging;

        unit 512 {

            vlan-id 512;

        }

   }

}

 

policy-options {

    community vpn-A members target:11666:9000;

}

 

routing-instances {

    customer-1 {

        instance-type l2vpn;

        interface ge-1/3/5.512;

        route-distinguisher xx.xx.100.71:1;

        vrf-target target:11666:9000;

        protocols {

            l2vpn {

                encapsulation-type ethernet-vlan;

                interface ge-1/3/5.512;

                site dis1.millbrook1 {

                    site-identifier 1;

                    interface ge-1/3/5.512;

                }

            }

        }

    }

}

 

 

 

Router #2 configuration looks like this:

 

interfaces {

    ge-1/3/5 {

        description TEST_l2vpn;

        vlan-tagging;

        unit 512 {

            vlan-id 512;

        }

    }

}

 

policy-options {

    community vpn-A members target:11666:9000;

}

 

routing-instances {

    customer-1 {

        instance-type l2vpn;

        interface ge-1/3/5.512;

        route-distinguisher xx.xx.100.72:1;

        vrf-target target:11666:9000;

        protocols {

            l2vpn {

                encapsulation-type ethernet-vlan;

                interface ge-1/3/5.512;

                site dis2.millbrook1 {

                    site-identifier 2;

                    interface ge-1/3/5.512;

                }

            }

        }

    }

}

 

Thanks for any input,

 

Paul
