Advanced Routing Capabilities

Intelligent Network Routing

The Cisco 921 supports a comprehensive range of dynamic routing protocols that make it suitable for businesses of all sizes. Whether your network is simple or highly distributed, the router adapts efficiently to changing network conditions.

Supported routing protocols include:

• Routing Information Protocol Version 1 (RIPv1)
• Routing Information Protocol Version 2 (RIPv2)
• Open Shortest Path First (OSPF)
• Border Gateway Protocol (BGP)
• Enhanced Interior Gateway Routing Protocol (EIGRP)

These protocols ensure efficient packet delivery, fast convergence, and improved network resilience.

High-Speed Cisco Express Forwarding

Cisco Express Forwarding (CEF) significantly improves routing efficiency by optimizing packet forwarding. Instead of performing repetitive route lookups, CEF creates optimized forwarding tables, allowing packets to be processed at high speed with minimal latency.

This makes the Cisco 921 an excellent solution for businesses running bandwidth-intensive applications such as:

• Cloud computing
• IP telephony
• Video conferencing
• Remote desktop services
• File synchronization
• Enterprise SaaS platforms

Secure VPN Connectivity

Connect Branch Offices Securely

Modern businesses require secure communication between headquarters and remote branches. The Cisco 921 supports multiple tunneling technologies, including:

Generic Routing Encapsulation (GRE)

GRE allows secure encapsulation of multiple network protocols over IP networks.

Multipoint GRE (MGRE)

MGRE simplifies VPN deployment by enabling dynamic tunnel creation between multiple branch locations.

Layer 2 Tunneling Protocol (L2TP)

L2TP provides secure tunneling for remote users and branch offices.

L2TP Version 3 (L2TPv3)

L2TPv3 enables Layer 2 VPN services across IP networks while supporting Ethernet traffic efficiently.

Built-In Enterprise Security

Security remains one of Cisco’s strongest advantages.

The Cisco 921 includes multiple security technologies designed to protect both users and sensitive business information.

Network Address Translation (NAT)

NAT hides private IP addresses from external networks while allowing secure Internet connectivity.

Access Control Lists (ACLs)

ACLs allow administrators to define granular traffic filtering rules that prevent unauthorized access.

DNS Protection

Features include:

• DNS Proxy
• Dynamic DNS
• DNS Spoofing protection

These technologies help secure DNS communications while improving network reliability.

Simplified Network Management

The Cisco 921 simplifies network administration through built-in services including:

DHCP Server

Automatically assigns IP addresses to network devices.

DHCP Relay

Forwards DHCP requests across network segments.

DHCP Client

Supports automatic IP configuration from upstream providers.

These features reduce manual configuration and improve deployment efficiency.

Enhanced Network Reliability

Business continuity depends on network uptime.

The Cisco 921 includes technologies that improve network stability:

Bidirectional Forwarding Detection (BFD)

Detects communication failures rapidly and minimizes downtime.

Next Hop Resolution Protocol (NHRP)

Supports dynamic VPN deployments while simplifying branch connectivity.

Performance Routing (PfR)

Automatically selects optimal network paths based on application performance.

Web Cache Communication Protocol (WCCP)

Improves application performance through efficient web caching integration.
