Dot1q tunnel VPLS support

Hello Guys,

I am configuring a dot1q tunnel VPLS since it suited our need for the client's requirements. To my surprise the 48 port tx we are using on our 7600 doesn't support this

7609-PPE1(config-if)#switchport mode dot1q-tunnel

Command rejected: Gi2/4 doesn't support 802.1q tunneling.

IOS is s72033-pk9sv-mz.122-18.SXD5.bin

Hardware is 48 SFM-capable 48 port 10/100/1000mb RJ45 WS-X6548-GE-TX

For me to establish a good VPLS in dot1q (dot1q in dot1q) multipoint connection, what hardware with port density is available for this one?

I didn't have any problem with OSM modules, but we have to be practical with the port density.

Your insights will be greatly appreciated.



Re: Dot1q tunnel VPLS support

For vpls to work the core facing should be a osm module.Configure IP routing in the core so that the PE routers can reach each other via IP. Configure MPLS in the core so that a label switched path (LSP) exists between the PE routers.For more info refer

Re: Dot1q tunnel VPLS support

I see, what I am concerned with our implementation right now is it has become too expensive if we're going to use either the 8 port gbic osm or the sup port. i guess we need the 48 port 10/100/1000tx that supports jumbo frames for the dot1q-tunnel
