I'm a little bit confused with the approach on how to get a failover with my current set-up.
From my attachment I want all my traffic will pass to primary router and split the internet traffic going to secondary router 3800 and my private corporate traffic will be taking the mpls serial 0/1/1. And it will also make a failover that all traffic to the secondary router when primary router fails. I'm using L3 switch where 2 routers are connected.
What is the best approach for this one?
Note: I have a tunnel from secondary router to pass my private corporate network.
a) Do i need to use HSRP?
b) Do i need to use dynamic local routing like EIGRP?
Please show me on how to start with the config.
