Static Routing and Dynamic Routing Protocol

[hirwan001]

Hi Experts

Does Medium Enterprise and Large Enterprise practice Static Routing or Dynamic Routing protocol to external network (with or without branches office). Any Benefit to use 1 of it over the other? Explain in simplify way. Thanks ....

In my experience, generally dynamic routing is used with all but the smallest networks, although there may be some static routing for "special" cases and/or static routes are redistributed into the dynamic routing topology.  For a couple of examples, sometimes a static default is used toward the Internet, or sometimes statics are use to route through a firewall.

The benefits of one versus the other are as they generally are, such as dynamic routing is a bit more complex to configure but static routing maintenance generally doesn't scale.

It all depends on the subnets count that you have either in Medium or Large enterprise. If you prefer the routing to happen dynamically for the subnets in the network without any manual intervention with respect to the best path selection then dynamic routing protocols like Eigrp , ospf, rip would be useful. 

A static routing does require your manual intervention in manually defining the best path to the destination PE end by making changes in the Administrative value. 

However, the static network subnets must again need to get redistributed , if you want those static entries to be learnt in the routing table of either eigrp or ospf protocols.

Hi 

Thanks for the reply. But what if a Network Engineer wants to remote in to the network to troubleshoot? and i hear, opinions divided on  configuration. some prefer Internet --> Router --> Firewall --> Switch --> devices and some prefer Internet --> Firewall --> Router --> Switch --> devices. For myself prefer Router first and Firewall after it, simply routers are more faster than firewalls.. if we put firewall first... network getting slow.... and availability will be depreciate... Also its not easy to hack router... since its protected by router self and ISP.. just my opinion and experience

What of it?  Unsure what sequence of physical devices has to do with remoting into network to troubleshoot it, beyond "knowing" the topology you're working with.

Why would the network get slow if the FW if first to connect to the Internet?

As to routers being faster than FWs, depends on the model of router vs. the model of FW.
