This looks to be a general routing related question rather than a "Linux
Advanced Routing and Traffic Control" (a.k.a. LARTC) question and thus
may be better answered elsewhere.

Ok...
I am trying to differentiate between the plethora of information
about having redundant, automatic failover routers and pretty much
decided on VRRP for the IP address failover mechanism.
VRRP is a good idea. I don't think I'd rely on one virtual redundant
router through. I would make router B be redundant for router A *AND
router A be redundant for router B. This way, your branch offices can
see two different routers that have the same capabilities. This way you
could route some load through one router and the rest through the other
while having both be redundant for each other.
I am having a bit of a problem sorting out what will work best for
automatic routing propagation between the two units and have been
looking at the possibility of using OSPF to accomplish this to avoid
having to enter routes into two different routers.
Yes, an interior routing protocol would be good. Based on my limited
experience I would recommend that you use either (preferably) OSPF or
possibly Interior BGP (a.k.a. IBGP).
Would OSPF work well for this? Are there better options?
You could look at things like RIP or ISIS, but neither of them will be
as good or bandwidth friendly as either OSPF or IBGP.
Thanks for any info,
You are welcome.
