Route VLAN traffic between two locations with GRE tunneling (With EXOS)

Route VLAN traffic between two locations with GRE tunneling (With EXOS)

We have x460 extreme switches in two different locations connected with L3 networking. I would like some suggestions on extending the vlan from one location to the other over l3. When I read about this, I realized that one of my option is L2-GRE and EXOS does not support it. Can I do this configuration using L3-GRE tunneling?
Please provide me some guidance on this.

Hi Ashwini,

Yes. You are right. EXOS will not support L2-GRE mode.

https://gtacknowledge.extremenetworks.com/articles/Q_A/Does-EXOS-support-L2-GRE-tunneling

Please find the below sample configuration for L3-GRE:
create vlan inet configure vlan inet add port 24 configure vlan inet ipa 1.1.1.1/24 create vlan users configure vlan users add port 1 configure vlan users ipa 100.0.0.1/24 create tunnel mytunnel gre destination 1.1.1.2 source 1.1.1.1 configure tunnel "mytunnel" ipaddress 2.0.0.1/24 configure iproute add 200.0.0.0/24 2.0.0.2 enable ipforwarding

Please let us know if you have any further queries.

Regards,
Karthikeyan

Thanks for using the Extreme Community Forum.

Please note that GRE tunneling of L3 traffic is possible in Extreme switches beginning EXOS 15.4 and above.

Please refer to page nos. 1300-1301 (EXOS_User_guide - version 16.1.) for configuration guidance on this issue.

Please let us know if you have any further queries.

Thanks,
