VPLS TLS and EVCS support?

GREGORY GEE
Level 1
Level 1

I have been trying to read the VPLS section on the following page to what versions of VPLS are supported.

http://www.cisco.com/en/US/products/hw/routers/ps368/products_module_configuration_guide_chapter09186a00801e5c06.html

I have a few questions:

1. What flavors of VPLS does Cisco support?

2. For the config exmaple on that page, is it TLS of EVCS?

3. Can I attach multiple vlan interfaces to a VFI?

4. Related to last question, does the packet that enters the VPLS over the core maintain the VLAN header of is it stripped? I'll have more questions about this depedning on the answer I get.

5. I am seeing conflicting reports in the forum and in the docs about which SUP card I need. What do I need to get my 6509 to work with VPLS?

Thanks,

Greg

1. Cisco supports VPLS as per draft-ietf-l2vpn-vpls-ldp-01 which has LDP as the signalling protocol.

Where as Juniper supports draft-ietf-l2vpn-vpls-bgp which has MP-BGP as the signalling protocol.

Cisco supports Flat-Vpls as well as H-VPLS.

2.The config shows Martini/EoMPLS(pt-pt) as well VPLS/TLS(multipoint-multipoint).

3.Yes ,You can attach multiple vlan interfaces to VFI.

They will be part of the same Vpls(VSI) instance.

4. Customer frames / VLANs are forwarded.The PE will only impose the VC and PSN Tunnel label.

If you are referring to QnQ tags,then only the SP Vlan will be stripped at the Ingress PE.

5.VPLS is supported with OSM+ as the core facing cards.

Martini L2VPN/EoMPLS can be supported on SUP720-3BXL.No requirement of OSM.

Mybe Cisco guys can comment if the above is incorrect.

1. I apologize. I guess I should have been more clear. I understand which draft Cisco used, it was more around vlan based and port based implementations I've seen on other vendors.

2. Sorry, I meant in the VPLS section. The section was a bit confusing saying where it kept mentioning the TLS and EVCS. But it never clearly showed which lines make it EVCS and which lines make it TLS. Are you saying that EVCS is actually just a reference to Martini?

3. Thanks. I guess this means vlan headers are maintained across VPLS.

4. I think I understand now. Mainly I was trying to see if Cisco's VPLS also did the same type4(vc-type vlan) and type5(vc-type ether) as they did with Martini. From what I iunderstand, Cisco's current VPLS is type4. Correct?

5. So for VPLS, I need at least a SUP2 MSFC2 with OSM+. For Martini, if I have a SUP720-3BXL, what card can I use to support MPLS core interface? Will a standard GE card work?

Thanks,

Greg

2.EVCS is a broad term which includes PT-PT,MP-MP and P-MP services.

Cisco supports PT-PT(martini) and MP-MP(vpls).

Pls find the below url for more info.

4.To be frank havent seen type5 config for VPLS on cisco,probably bcoz of redundancy on the PE-CE link.(ME-H-VPLS)/VPLS-LDP(Sajjasi).

See section 10.1.3 of draft-ietf-ppvpn-vpls-ldp-01.txt.

5.With Sup720’s PFC3bXL and DFC3bXL performing the EoMPLS(martini),any module

can be the uplink to the MPLS core.
