Use of rackmount Gigabit Ethernet router?

Hello,

I would like to know what is the use of Gigabit Ethernet router like RB1100AHx2 and when it comes handy? :question:

It comes handy when you need to route corresponding amount of data especially with ipsec encapsulation.

It also comes in handy when you keep your network gear in a locked server rack instead of on a shelf by the TV.
