You might join me in poking Paul to implement vrrp in the quagga suite ;)

Other options might indeed be carp/ucarp/vrrpd/keepalived;
or you might consider using L3 switches and combine those with your quagga 
That way you could use quagga for bgp, and build an ospf mesh with your 
quagga boxes and the layer3 switches.
Next, use the layer3 switches' HRSP functionality, and go for layer3 
redundancy (which ospf gives you) at anything in your core.
You might think of those switches as your 'core'switches. They will cost a 
few euro's, but tons less than the routing boxes from any vendor.

Just my EUR 0.05  (21%VAT ex.)
