I am setting up 2 Vyatta routers that will serve as redundant failover core routers out to the backbone of our ISP. They will be serving for routing between other branches and the ISP and bandwidth management.
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,
