Routing Protocols and Configuration
The ISR4221-SEC/K9 Cisco ISR 4221 Integrated Service Router is a next-generation integrated services router that provides advanced security, voice, and wireless capabilities for small to medium-sized businesses and enterprise branch offices. It supports various routing protocols, including:
- Border Gateway Protocol (BGP): BGP is a routing protocol used to exchange routing information between routers in different autonomous systems (AS). BGP is typically used to connect to ISPs or to other organizations that have a separate AS.
- Enhanced Interior Gateway Routing Protocol (EIGRP): EIGRP is a Cisco-proprietary routing protocol that is based on IGRP. It is a distance-vector protocol that uses metrics to determine the best path to a destination.
- Open Shortest Path First (OSPF): OSPF is a link-state routing protocol that uses a link-state database to store routing information. It uses a shortest path first (SPF) algorithm to determine the best path to a destination.
- Routing Information Protocol (RIP): RIP is a distance-vector routing protocol that uses hop count as its metric to determine the best path to a destination.
- Static routing: Static routing is a manual method of configuring routes in the routing table.
- To configure the ISR4221-SEC/K9 router, you can use the command-line interface (CLI) through a console or remote connection. The CLI allows you to configure the router's interfaces, routing protocols, security features, and other settings. Cisco Configuration Professional (CCP) is a web-based interface that can be used to configure the router.
- Before configuring the router, it is recommended to have a deep understanding of the routing protocols, network topology, and security measures. Additionally, it is important to have a strong understanding of the requirements of the network and the specific use case, to properly configure the router to best suit the needs of the organization.
