Terminating multiple IPsec tunnels on an interface

rbit0965 — Wed, 04 Sep 2013 19:06:36 GMT

Currenly all routing must take place on our core network. (due to backup ipsec tunnels and faster MPLS circuts)

Here is what we want to do but I am not sure how to accomplish this.

We have four IPsec Tunnels that we do not want to be routed to each other without touching the core network first.

Our current setup has all four IPsec tunnels terminating on different tunnel interfaces but all on the same virtual router. (vr-ipsec)

Traffic destined for the core comes over the vr-ipsec and out eth10 for the core.

However traffic for a remote site comes down the same virtual router and back up the correct tunnel interface. Skipping the core all together.

What we want to do is terminate all the tunnels onto an interface facing the core.

Each tunnel interface will have its own IP address.

The core will know how to get to each remote site via the assigned IP on each tunnel.

I can draw pictures if needed.

Thanks

Hello,

Can you provide some network diagram?

Hi,

Each tunnel should have his own zone. they can be part of the VR but they have to use default route which say defualt gateway is the core.

Remote1 -> tunnel1 -> zone1 in 10.1.1.0 - default gatway => core

Remote2 -> tunnel2 -> zone1 in 10.1.2.0 - default gatway => core

Hope help.
