Fail Over and Load Balancing for VPN and MPLS Network

Jagadeesh

HI,

We have a setup of sonicwall TZ400 firewall at two locations Head office and Branch Office. And we have MPLS network between these two location. We have created VPN between these two office, to use during MPLS network down time. We need to use this VPN and MPLS simultaneously with load balancing and fail over. we Need help on the above to achieve this.

If any one have solution kindly let me know.

thanks in advance

regards,

Hello @Jagadeesh,

We can certainly set up failover for the VPN and MPLS connection using Network Monitoring. Please take a look at the KB below.

@Jagadeesh,

Honestly, I haven't dealt with something like this myself, but I can see the only option that could be used is multipath routing.

Are you using route-based VPN? If yes, I think we can select the first interface as VPN and the other as MPLS or vice versa as per your requirement and test this out.
