EoMPLSoGRE Up but cant ping between hosts

Nicholas Peet

Level 1

Hi,

Got 2 Cisco 6500's and want to span the layer 2 so we can migrate VM's from one to the other.  I have got xconnect on an interface and a GRE tunnel up and running.  xconnect is up and senting and receiving but I cannot ping between hosts across the link.

Hello Nick

What is the module on which you are having Core facing and Customer facing interface on the 6500 switch. Are they Lan cards or Wan cards?

Regards

Vinit

Thanks

Also, is the pseudowire ping working ? I think that should work if the circuit is up.

Thanks
--Vinit

Hi,

Yes the pseudowire ping is successful.  I have both LAN and WAN connected to ports on the CEF720 48 port 10/100/1000mb Ethernet Module.  

I have a SIP-400 Module but no cards in it yet.  Think I need 1 or 2 SPA-2X1GE 2-Port Gigabit Ethernet Adapter.  If this is the case can I have just have 1 SPA-2X1GE 2-Port Gigabit Ethernet Adapter and use one port for LAN and one for WAN?

Also can you give me any pointers for how the configuration would look with this card in place?

Also have the SUP720-3B as the supervisor.

Thank you for you help.

Kind Regards

Nick

Hello Nick

thanks for the information. I think you can try using the SIP-400 card than CEF720 card. there is a limitation when using CEF720 as a Core interface card for L2VPN.

Vinit

Thanks

Hi Vinit,

I have the LAN and the WAN configured on the CEF 720 at the moment.  I get send and receive on the xconnect but cant ping between host, this is why I think that I need the SPA-2X1GE 2-Port Gigabit Ethernet Adapter in the SIP-400 instead and then configure the LAN and WAN ports on this instead.

Cisco documentation is limited on what I exactly need, they do mention about the SIP-400 being needed with the 2 port adapter card as AToMoGRE (in my case EoMPLSoGRE) is not supported natively in the sup720.

Have you used this configuration before?

Kind Regards

Nick
