The Router Rip Cisco command

Cisco 'router rip' Command

The 'router rip' command is used to enable or disable the Routing Information Protocol (RIP) on a Cisco router. RIP is a dynamic routing protocol that uses hop count as its routing metric, meaning the number of hops (or intermediate routers) a packet must pass through to reach its destination.

The syntax for the 'router rip' command is:

router rip [af]

Where:

• af is the address family for which RIP is to be enabled. For example, "ipv4" or "ipv6".

How to Use the 'router rip' Command

You can enable RIP by using the following command:

router rip ipv4

This will enable RIP over IPv4 on the router. To enable RIP over IPv6, use the following command:

router rip ipv6

To disable RIP, use the following command:

no router rip

This will disable RIP on all address families and networks.

Equipment Supported

The 'router rip' command can be used on any Cisco router that supports RIP. Note that RIP is not supported on all Cisco switches.

RIP is a simple and easy-to-configure routing protocol, making it ideal for small to medium-sized networks. However, RIP is not recommended for large networks due to its hop count metric, which can lead to routing loops.

Use Cases for 'router rip'

Here are some use cases for the 'router rip' command:

• Enabling RIP on a router to allow it to participate in a RIP network.
• Enabling RIP on a single interface to allow it to exchange routing information with a neighboring router.
• Disabling RIP on a router to prevent it from participating in a RIP network.

Additional Information

• RIP Version 1 (RIPv1) is a classful routing protocol, meaning it does not support subnet masks.
• RIP Version 2 (RIPv2) is a classless routing protocol, meaning it supports subnet masks.
• RIP uses port 520 for communication.

Conclusion

The 'router rip' command is a simple, yet powerful command. It can be used to enable or disable RIP on a Cisco router. RIP is a dynamic routing protocol that uses hop count as its routing metric. RIP is an ideal routing protocol for small to medium-sized networks.

router rip Usage Examples

The Cisco command 'router rip' is used to configure RIP (Routing Information Protocol) parameters and enable RIP routing on a router. Here are some examples of how you can use the 'router rip' command:

1. Enable RIP Routing Globally:

router rip

This command enables RIP routing globally on the router. All RIP-enabled interfaces will start participating in RIP routing.

1. Enable RIP on a Specific Interface:

router rip
interface GigabitEthernet 0/1

This command enables RIP routing on the specified interface (GigabitEthernet 0/1). Only RIP packets received on this interface will be processed.

1. Configure RIP Network Parameters:

router rip
network 192.168.1.0

This command configures the router to advertise the network 192.168.1.0 in RIP updates.

1. Configure RIP Distribute List:

router rip
redistribute connected route-map MAP_NAME

This command configures the router to redistribute connected routes into RIP updates based on the specified route map (MAP_NAME). The route map can be used to filter and modify the redistributed routes.

1. Configure RIP Timers:

router rip
update-period 60
flush-period 180

This command configures the RIP update period to 60 seconds and the flush period to 180 seconds. The update period is the interval at which the router sends RIP updates, and the flush period is the interval at which the router removes old routing information.

1. Configure RIP Authentication:

router rip
authentication mode md5
authentication key-chain RIP_KEY

This command configures RIP authentication using MD5. The RIP_KEY key chain contains the MD5 authentication keys used to secure RIP updates.

1. Configure RIP Passive Interface:

router rip
passive-interface GigabitEthernet 0/2

This command configures the specified interface (GigabitEthernet 0/2) as a passive interface for RIP. Passive interfaces do not send RIP updates but only accept and process RIP updates received on the interface.

1. Disable RIP Routing Globally:

no router rip

This command disables RIP routing globally on the router. All RIP-enabled interfaces will stop participating in RIP routing.

These are some common examples of how you can use the 'router rip' command to configure RIP routing on a Cisco router. The specific configuration commands you use will depend on your network requirements and topology.
