GRE Tunnel with OSPF between Vyatta and Cisco router

Hello,

 

I have configured a GRE Tunnel between a Vyatta and Cisco router. First it was the version 5400 of the Vyatta Firewall and the tunnel configuration works fine with the VRRP address of my firewall cluster. The OSPF Neighbor was ready and exchanged routes.

After the upgrade of the Vyatta to version 5600 this configuration didn´t work any more. The GRE Tunnel is up but the OSPF neighborshipment is lost every 10 - 20 seconds and so the exchange of routes didn´t work.

I have now configured two GRE tunnels from the Cisco router towards the interface IP of the Vyattas. The first tunnel works well but if the active Vyatta fails there is no IP communication possible over the seond GRE Tunnel.

 

Has anybody an idea or a soluton for that?

 

Best regards

 

Roger
