2 MX84s with 1 ISP(500Mbit/s up and down) and 1 ISP(100Mbit/s up and down)

[ToddW]

We currently have 1 MX84 in place with a main ISP for WAN1 uplink at 500 Mbit/s up and down.  We have the second WAN link connected to the other ISP for backup that is 100 Mbit/s up and down.

We have a spare MX84 and it seems to me to make sense to use it as a warm spare.

Is there easy documentation somewhere on who to configure the 2 MX 84s with the 2 different ISPs so we are in the best HA possible configuration?  We want to use cisco anyconnect as well for our vpn solution.

Take a look at the part that talks about Virtual IP.

What you really want to do is plug both MX into both ISP (or at least both MX into one ISP).  To do this you'll often need a /29 of IP address space.

For Anyconnect you don't have to use a virtual IP, but it might take 10 minutes for clients to be able to connect again after a failover.
