NETWORK APPLICATIONS
Secure Network Connectivity
Network security has become a fundamental building block of any network, and Cisco routers play an important role in embedding security at the
customer’s access edge. Recognizing this requirement, the Cisco 1800 Series fixed-configuration routers are equipped with the Cisco IOS Software
Advanced IP Services feature set as the default software image (except for the Cisco 1801). This Cisco IOS Software feature set facilitates hardware-
based encryption on the motherboard and provides a robust array of security capabilities such as Cisco IOS Firewall, URL Filtering, IPS support,
IPSec VPNs (DES, 3DES, and AES), Dynamic Multipoint VPN (DMVPN), Easy VPN server and client support, NAC for defense against worms
and viruses, security policy enforcement, Secure Shell (SSH) Protocol Version 2.0, and Simple Network Management Protocol (SNMP) in a single
solution set. As Figure 2 demonstrates, the Cisco 1800 Series fixed-configuration routers help enable customers to deploy high-performance,
concurrent, mission-critical data applications with integrated, end-to-end security.

Figure 2. Securing Small Branch Office with a Cisco 1800 Series Fixed-Configuration Router
Highly Available Internet Connectivity
The Cisco IOS Software Advanced IP Services feature set offers basic and advanced routing capabilities to deliver failover protection and load
balancing. These capabilities include Border Gateway Protocol (BGP), Open Shortest Path First (OSPF) Protocol, Enhanced Interior Gateway
Routing Protocol (EIGRP), and Routing Information Protocol (RIP) routing protocols along with dial-on-demand routing (DDR) and reliable static
routing using object tracking. Each of the Cisco 1800 Series fixed-configuration routers is equipped with an ISDN BRI or V.92 analog modem port,
and an Ethernet port for secondary WAN backup connection. If the primary DSL, cable, or Ethernet-access WAN is disconnected for some reason,
the router will detect this failure and will automatically fail over to the secondary backup WAN. As Figure 3 and 4 demonstrate, the Cisco 1800
Series fixed-configuration routers help enable customers to deploy high-performance and highly-available, mission-critical business applications.
