L2VPN over MPLS

Hi everyone,
I'm trying to establish connection between to PC. I have xconnect beetven cisco 7600 router and ubr7246.
On 7600 PE router I use l2vfi

******************************************
l2 vfi TEST manual
vpn id 1111
neighbor 10.0.0.2 encapsulation mpls

inter vlan 1111
no ip address
xconnect vfi TEST

*******************************************
I have PC connected on cisco 6500 port (which is behind 7600PE) , access port 1111.

On ubr4246 I configured static mapping:
*******************************************
cable l2vpn 0018.6833.7fe4 TestModem
service instance 1111 ethernet
encapsulation default
xconnect 10.0.0.1 1111 encapsulation mpls
********************************************
and command: cable l2-vpn-service xconnect nsi mpls

For test I use Cable Modem EPC2434.
Xconnect is always up, bud I don't have packets from ubf7246 to 7600PE

********************************************
ubr7246#sh mpls l2transport vc 1111 detail
!
VC statistics:
packet totals: receive 32038778, send 1
*********************************************

I can't ping two PCs, one coneccted on cisco 6500 and other behind Cable modem.
Maybe Cabel Modem EPC2434 do not suppoort L2VPN capabilities.

**********************************************

ubr7246#sh cable modem 0018.6833.7fe4 verbose
!
L2VPN Capabilities : {L2VPN=N, eSAFE=N}
!

Is this problem with Modem, or configuration file on modem, or I need somehow to enable L2VPN through configuration file?

Does anyone have expirience with this and how it work?

Thanks!

Yes I have used L2VPN over

Yes I have used L2VPN over MPLS

However on my network we configured the cable end in the cm config file. Your cmts-based config looks OK though.

For the PE end I have tested with Cisco 7200 and Juniper MX. On the 7200 the config was quite different to what you quote. Basically you set this type of thing :

pseudowire-class PW-CLASS-TYPE5
encapsulation mpls
interworking ethernet

interface gig0/1.1234
encaps dot1q 1234
xconnect encapsulation mpls pw-class PW-CLASS-TYPE5

On the 7600 can you do config similar to above?

(And for terminating the pseudowire on Juniper MX you use "protocol l2circuit ..." configuration commands)

With regards to your modem not supporting L2VPN, that doesnt mean it wont work. I just means that some of the other handy features like DUT filtering will not work. So yes you are best off with an L2VPN capable modem, but it doesnt stop you from doing at least some basic testing with other non-compliant modems.

Hope that helps!

I thinks you need this Conig File

Ronel, thanks for reply. It

Ronel, thanks for reply. It works with manual xconnect config on UBR, but now I have problem when I use config file.
In your example of config file, where you put peer ip address, vc id etc.

What represent this 0x01043230303102070405010a0a0a02050504010107d10604000007d10704000007d and 0x0803ffffff0509010432303031080104 ?
Is this PEER IP VCID VCID VCID, how can I see it?

Thanks
