A device on a network are gateway, router, bridge, switch, hub, repeater, multilayer switch, protocol converter, bridge router, digital media receiver, proxy, firewall, and network address translator. A computer on a network is called a networking computer. http://en.wikipedia.org/wiki/Computer_networking_device
The routers are configured with different versions of RIP. R2 is not forwarding the routing updates. The R1 configuration should include the no auto-summary command. The maximum path number has been exceeded.
Security between networks is implemented in an intermediary device (a router or firewall appliance) at the perimeter of the network. The firewall function performed by this device permits only known, trusted data to access the network.

This device is called a ROUTER. Routers are by default configured to not pass the broadcast traffic to another networks to which it connects. But by some means it could be also a SWITCH - sometimes it can be configured to filter different type of network traffic.
Routers usually, if not always, include a firewall. This is the only device I know of.

Computer firewall is a security software which acts as a barrier and protects the system from black-hat intrusion attempts. Firewalls also block communication attempts into or out of your computer; certain types of malware or software bots that attempt to send or receive data messages will be blocked. A firewall program is your computers perimeter fence, designed to keep bad guys out, and to prevent data passing into/out of your computer. Firewalls are configured in software and hardware devices with specific criteria to block or prevent unauthorized access. It has the packet filtering mechanism which checks for the packets that contain data, prevents or blocks it depending upon the rules programmed in it. Reference source: personalfirewall.comodo.com
