Hello all,   Running into a bit of a tricky situation getting backup internet between two buildings. Here's the scenario.   Building A has its own ISP and an MX100. Building B has its own ISP and an MX67.   We've got a connection between the two buildings between two Catalyst switches hooked up to their respective MX hardware. End goal is simple WAN redundancy using each buildings ISP as failover. Obviously warm spare and standard HA is not possible due to mismatching MX models..What are my options here? Is any kind of manual VRRP configuration even feasible in this scenario? Admittedly my networking knowledge is in the walking stages - so forgive any ignorance on potentially obvious solutions. I'm truly confused what my next steps should be here with my current scenario.   Thanks for any suggestions. ... View more
