We do this currently. There are two MPLS routers with VPLS ports each connected to a switch bank for redundancy.
VPLS performance on Mikrotik is lacking though at above 1Gbps range, so I’m reverting most my network back to just plain VRRP between two routers and OSPF ring back to the sources.

This is a fairly common configuration. Well, I don't know about 3, but definitely 2 routers. It gives you redundancy, allows you to perform in place hardware and software upgrades, etc. Another common design is multiple switches and routers at a site. On the "lan" side there are 2 switches, crosslinked to two routers. The routers run vrrp between them - boom, instant first hop redundancy. On the "wan side" you've got two switches with crosslinks and ospf between the routers.

The goal was to improve reliability by having critical links come into different routers, allowing site access if any router actually failed. The system is setup with OSPF and MPLS routing between them. I only ever installed 3 routers at one location, though (other site have only 1 or 2 MikroTik routers). It has been 2 years now, and everything has worked great at the 1, 2, and 3 router sites. The use of the RB750UP routers has allowed for remote rebooting when necessary, and I have not had a single router failure. I'm working on a revision to the design, and I'd like to know if anyone else intentionally runs multiple routers like this. Any practical benefits to running multiple PoE routers vs running a single router and a single PoE switch?
