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.

On user created VR.. looks like it's not supported in 16.1 EXOS release

Hi Ashwani,

Are you trying to configure GRE tunnel on a default VR or a different VR?

As discussed earlier following set of Hardware supporting this feature:

Summit X460,X480,X650, X670 and E4G
BD8900 (G96T-c,10G24-x,G48T-XL, G48X-XL,10G8X-XL,40G6X-xm)
BDX8 (all I/O cards)

Note:

Provided all blades in the chassis or nodes in a stack need to support GRE tunnels or else the feature cannot be configured or enabled.

Not sure in your scenario if you are using any stack X460 switch or stand alone switch to achieve this. If any stack switch then the above point needs to be considered.

Coming to the recommended software version for this hardware(X460) : Exos16.1.3.6p1-9 is currently in use.

Hi Karthikeyan,

Was trying to configure today and I realized that GRE tunneling doesn't support on virtual router. Is it supported in later versions of EXOS 16.1?

Topology is same as you have. SW1 in location A -- Core ----SW2 in location B.
And we create a tunnel between SW1 and SW2.
