Hi there!
is is possible to use VC Type 5 in spite of Ethernet SVI in EoMPLS ?
I know that VC Type 5 (Ethernet Type) is port based EoMPLS and VC Type 4 (Ethernet vlan) is VLAN based EoMPLS.
But I found that despite Ethernet SVI configured, the VC type is Type 5
How could I adjust the VC Type? I heard that there is no option to manipulate the VC Type in Cisco Equipment.
(the VC type depends on the negotiation between PEs, right?)
Here is an example (The router spec is C6509 SUP720-3BXL)
Router#sh mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------- --------------- ---------- ----------
Gi3/46.34 Eth VLAN 34 1.1.1.1 34 UP
Router#sh mpls l2transport binding 34
Destination Address: 1.1.1.1, VC ID: 34
Local Label: 409
Cbit: 0, VC Type: Ethernet, GroupID: 0
MTU: 1500, Interface Desc: == e: EoMPLS Connect ==
VCCV Capabilities: Type 2
Remote Label: 2618
Cbit: 0, VC Type: Ethernet, GroupID: 0
MTU: 1500, Interface Desc: == e: EoMPLS Connect ==
VCCV Capabilities: Type 2
interface GigabitEthernet3/46.34
description == e: EoMPLS Connect ==
encapsulation dot1Q 34
no ip redirects
xconnect 1.1.1.1 34 encapsulation mpls
===============================================
opposite PE is as below (this router's spec is C7609S RSP720-3CXL : 12.2(33) SRD4)
pe02.sel.ia#sh mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------------- --------------- ---------- ----------

Destination Address: 2.2.2.2, VC ID: 34

Hello,
I have tried in my network and it is not supported on SRD3 (as I don't have SRD4 was not able to test)
but it is well supported on SRE2. (If you are planning to upgrade I should recommend to use SRE4 )
(config-pw-class)#interworking ?
ethernet Ethernet interworking
ip IP interworking
vlan VLAN interworking

I selected wrong type. so I delete my post in the document. and re-posted my question on discussion

I wonder why you chose the document type, as we cannot reply but just edit it.
Anyway for vlan mode eompls cisco devices can support both vc 4 & vc type 5.This depends on which platform we are configuring.
i.e: for eompls tunnel between 2 7200 or between cat6k/7600 and 7200 VC type 4 is negotiated (as 7200 does not support anything else).
For tunnels between 2 cat6k/7600 vc 5 is chosen.
For port mode eompls vc 5 type is always negotiated.
Also about vlan mode eompes the cat6k/7600 tries to negotiate VC type 5 by default. If the peering
platform is incapable of reinserting the vlan tag, then the PW falls back to VC type 4. You can find out the vc type being negotiated using "show mpls l2 binding

I think between 2 7600 routers itself we can forcefully make it to operate in vc-type 4 by using "interworking vlan" command on a pseudowire-class and attach it to the particular vc. Config example is shown here...

There is no option(interworking vlan) on C7609S
I use IOS 12.2 33 SRD4 and ES+20G as a module.
Is it possible to use interworking vlan command?
What IOS should I use in order to config interworking vlan?
Thanks & Regards

Sorry that I forgot to mentioned the release. This was introduced from
SRE onwards.
