SRX345 Dual ISP Configuration

  • 1.  SRX345 Dual ISP Configuration

    Hi everybody,

    I am moving a 2 node cluster SRX345 to a new data centre.
    I am going from one a physical cable Internet link to a two physical cable Internet link for ISP redundancy 
    I would like to use the reth1 interface for web traffic on the primary ISP link and route Site To Site VPN traffic across through the secondary ISP link maybe creating a reth3 interface?
    My question is how to route specific traffic and how I can fail over to a second link in the event of an ISP outage. I'm not sure is it is Dead Peer Detection of something like set routing-options static route 0.0.0.0/0 qualified-next-hop [IP-ADDRESS} preference 6 would work.
    Thanks
