Actually, having systems run OSPF is the Solaris standard for interface
failover these days (OSPF-MP) which uses Quagga.
The end system has two links, each are on different layer 3 subnets. A
host announces its loopback IPs over both links. When an interface or
upstream switch or router fails, the network uses the remaining path.
Using ECMP, it also creates a reasonable alternative to Spanning Tree in
the net where you push layer 3 all the way down to the hosts.
Running routing protocols out to the host is becoming more common these
