MPLS VPLS VPN

I am having two Cisco 6509(R01,R02) connecting back to back with MPLS LDP enabled then i try to test VPLS VPN with VLAN AC.

R01's LDP Router ID is 111.90.180.8 , R02's LDP Router ID is 111.90.180.9. I got below output:

R01#sh mpls l2transport vc

=================================

As you can see, VC 101 is up on R02 but VC101 is down on R01. If i shutdown VC101 on R01, it report down too on R02.

Am i doing something wrong?

Hello Ty Chan,

Could this be a problem?

R01

    Targeted Hello: 111.90.180.8(LDP Id) -> 111.90.180.9

R02

    Targeted Hello: 172.16.32.7(LDP Id) -> 111.90.180.8, LDP is UP

Hi Ty Chan,

What type of Ethernet / WAN cards you're using on R1 and R2 facing to each other?

Could this be a hardware limitation?

For VPLS you have to use ES/ES+ or SIP- cards.

Hi Sergey,

I am using cat6509 with

1. R02 is s3223_rp-ADVENTERPRISE_WAN-M), Version 12.2(33)SXI4, RELEASE SOFTWARE (fc3)

2. R01 is s3223_rp-ADVENTERPRISE_WAN-M), Version 12.2(33)SXI3, RELEASE SOFTWARE (fc2)

3. R01 is using WS-X6148-GE-TX 48 port 10/100/1000mb EtherModule Rev. 7.1

4. R02 is using WS-X6148A-GE-TX 48-port 10/100/1000 RJ45 EtherModule Rev. 4.1

any suggestion?

Hi Ty chan,

SVI-based EoMPLS (SW-based or WAN-based EoMPLS) requires OSM/SIP/ES+ for the Core-facing interfaces. It will not work with WS-X6148-GE-TX.

Re: MPLS VPLS VPN

Hi Sudeep,

I using "WS-X6516A-GBIC SFM-capable 16 port 1000mb GBIC Rev. 4.7" facing core and " WS-X6148-GE-TX 48 port 10/100/1000mb EtherModule Rev. 7.2" facing to customer (CE) on both routers.

Regards, CT

Re: MPLS VPLS VPN

Hi ty,

If its just 2 switches why dont you just use EoMPLS? Is there a compelling reason to use VPLS.

Regards.
