gre tunnel over redundant links - failover not working

Hi all,

 

I try to establish gre tunnel over redundant links, if the primary link down the traffics will redirect to the backup link.

But now it doesn't work as I expected. I tried qualified next-hop also not working and the keepalive timer for gr interface is not supported in srx platform. I was wondering if there is other option to make it work.

 

thanks.

Re: gre tunnel over redundant links - failover not working

Configure a loopback interface and source the tunnel from that.  As long as both links have a route to the loopback, this should work.

 

Cheers,

Re: gre tunnel over redundant links - failover not working

In that case, you can create two GRE tunnels and run either RIP or OSPF over them - use metric/cost to bias your traffic via the preferred GRE tunnel while both sites are up.

 

Hope this helps
