LACP over GRE tunnel

Tuesday

Hello,

 

Is it possible to configure LACP to work over a gre tunnel?

Alex

Hello Rocketfkinscience,

 

GRE creates virtual tunnel in which you specify the source and the destination for the GRE tunnel, with this in mind you can use LAG/LACP to provide connectivity to the tunnel, meaning that the tunnel endpoints can be on the physical interface that connects towards the other end point.

 

if you are trying to get LACP within the GRE, well this is not supported.

 

let me know if I answered your question, or if you have any doubts or comments.

Cheers,

Benjamin

Can't do LACP over GRE sorry.

 

What do you want to achieve? Perhaps load balancing or HA across multiple GRE tunnels?
If that's the case, you can use your dynamic routing protocol.

Hello Luke,

 

This is how the topology would look like.

And yes, the end target is to loadbalance the packets.

Hi,

GRE is basically IPoIP. I've heard that it could be possible to also do ANYoIP with GRE, but ...

Wrt to Juniper you'd want to choose a different tunneling mechanism (MPLS?!) to achieve this.

then again I don't think the MC-LAG config will be so useful with the GRE tunnel, the GRE tunnel is very limited, i don't think you can implement MC-LAG and a GRE tunnel to use it from two different MXs.

 

Maybe MC-LAG will resolve your problem altogether without the need for the GRE tunnel. look at the following documents:

What's in between the MX routers on the IP link? Is this a WAN connection, internet connection, or a direct connection between the routers?
