GRE Tunnels Fail Over IPSec with Failover Setup

Jump to solution

Dear All,

I am trying to setup GRE over IPsec with Failover on Two Routers. I have the config for one router below(the other router config is a mirror of this one). I think all my settings are correct however the GRE tunnels fail for some reason.

I would be very grateful if anyone could help me out.

Warm Regards,

Vito

Re: GRE Tunnels Fail Over IPSec with Failover Setup

We were able to resolve this after Adtran was involved. We had to purchase 5 PSV's to get Adtran engineers to look and resolve the issues. Now everything works.

If anyone is interested to implement the scenario where crisscross connections fail-over correctly allot of work is involved and I suggest purchasing Adtran PSV's work work with an engineer.

Vito:

Thank you for asking this question in the support community.  Can you confirm that the track is in a passing state and the proper default route is in the route table?  I noticed you have the probe configured to pass after 40 consecutive successful pings (of 3 seconds between pings); therefore, in your case, the default route might be removed via the track.  When the default route is correct, and the probe/track are passing, then I suggest you debug the IPSec tunnel to verify that it is negotiating properly, then make sure the GRE traffic is being routed properly. Furthermore, there are a few things that I recommend you correct.   

The ACL referenced in the "tunnel-failover" policy-class is "tunn" instead of "tunnel."   

!

ip policy-class tunnel-failover

  allow list self self

  allow list tunn policy Failover

!

There is not administrative distance on the backup tunnel route:

!

ip route 0.0.0.0 0.0.0.0 xx.xxx.173.1 track VPN200Primary

ip route 0.0.0.0 0.0.0.0 xx.xxx.62.193 100

ip route 10.10.10.0 255.255.255.0 tunnel 1 track VPN200Primary

ip route 10.10.10.0 255.255.255.0 tunnel 2 <admin distance>

I hope that makes sense, but please do not hesitate to reply with any additional questions or information.  I will be happy to help in any way I can.

Its not really resolved yet. I have been on with support trying to solve this problem for over 1week plus now.

I may have a routing loop somwhere.

Re: GRE Tunnels Fail Over IPSec with Failover Setup

I had to remove the following line from the config as per manual:https://supportforums.adtran.com/docs/DOC-2310

Routing Settings

The firewall has been setup to take its cue from the routing engine, so a properly

functioning routing table is critical. If the routing table is not setup correctly, especially in

the case of funneling all Internet traffic through the GRE to a central location, recursive

routing errors may occur.

The first step to avoid routing errors is to create a static route to the GRE tunnel peer.

This will force the router to always use this path when accessing the GRE tunnel peer. If

this route was not entered, and the default route was pointing through the GRE tunnel, the

only way the router could get to the GRE tunnel peer would be to traverse the GRE

tunnel, which results in a recursive routing error. Using the example configuration, the

route would be configured in this manner in the command line:

ip route <GRE Tunnel Peer IP> 255.255.255.255 <Internet Gateway>

ip route 65.162.109.201 255.255.255.255 208.61.209.254

------------------------------------------------------------------------------------------

When I had a route simular as above on my routers the Tunnel 1 was going down all the time when there was traffic send to it.

Also the SSH connection to the Primary was going down as well and I had to constantly reconnect. Maybe there was a routing loop somewhere.

At this point I am pretty much stuck.

Now both tunnels are down

This is still being worked on. I will write something up when positive results are available.

Re: GRE Tunnels Fail Over IPSec with Failover Setup

Jump to solution

We were able to resolve this after Adtran was involved. We had to purchase 5 PSV's to get Adtran engineers to look and resolve the issues. Now everything works.

If anyone is interested to implement the scenario where crisscross connections fail-over correctly allot of work is involved and I suggest purchasing Adtran PSV's work work with an engineer.
