[j-nsp] l2vpn tagged PE port to untagged PE port

[Paul Stewart]

Thanks David. I went back and checked. ummm. had the VLAN maps on the
opposite side (geesh!)

 

Appreciate the second set of eyes.. ;)

  Simply applying an 'input-vlan-map pop' and 'output-vlan-map push' on the
trunked port (ge-1/3/9) didn't do the job ?  I used to have to do that all
the time and don't recall encountering problems.  The routing-instance
encapsulation will need to be 'ethernet' on both sides once you do that.

Hi folks.



Have built an l2vpn session but ran into an issue.  One side of the session
is handed off on a trunked port:



[edit interfaces ge-1/3/9]

flexible-vlan-tagging;

speed 100m;

encapsulation flexible-ethernet-services;

}

unit 444 {

   description "OTA Testing";

   encapsulation vlan-ccc;

   vlan-id 444;

}



The routing instance looks like this:



[edit routing-instances OTA-Testing]

instance-type l2vpn;

interface ge-1/3/9.444;

route-distinguisher xx.xx.xxx.71:444;

vrf-target target:11666:9444;

protocols {

   l2vpn {

       encapsulation-type ethernet-vlan;

       interface ge-1/3/9.444;

       site dis1.millbrook1 {

           site-identifier 71;

           interface ge-1/3/9.444 {

               remote-site-id 59;

           }

       }

   }

}





The other end though has an untagged port (straight Ethernet).  I cannot
figure out how to hand this off and keep getting an encapsulation mismatch
on the l2vpn session?



{master}[edit interfaces ge-2/1/3]

speed 100m;

link-mode full-duplex;

encapsulation ethernet-ccc;

unit 0;



Routing instance:



{master}[edit routing-instances OTA_Testing]

instance-type l2vpn;

interface ge-2/1/3.0;

route-distinguisher xx.xx.xxx.xx:444;

vrf-target target:11666:9444;

protocols {

   l2vpn {

       encapsulation-type ethernet;

       interface ge-2/1/3.0;

       site core1.toronto1 {

           site-identifier 59;

           interface ge-2/1/3.0 {

               remote-site-id 71;

           }

       }

   }

}





I contacted JTAC and they suggested a VLAN map to pop and push. this didn't
work . I previously had this labbed up and can't find my notes ;)



Layer-2 VPN connections:



Instance: OTA_Testing

 Local site: core1.toronto1 (59)

   connection-site           Type  St     Time last up          # Up trans

   71                        rmt   EM





Any thoughts on how I can fix this?



Appreciate it,

Paul
