Hello specialists,
I am investigating and making some probes with VRRP before applying to the main router in the company. One of my question is about the whole configuration a router could have. For example, DHCP servers, leases, firewall rules, Routing protocols, etc must be in both routers? When modifying a part of configuration, must I perform the same modification in the second router? Isn´t a way to behave as only one router?

Thank you very much. May be it is possible and I haven´t found it yet.

Ivan
