Hi there, dear members!
This post contains an example for configuring RIP version. Please check the information displayed below.
BACKGROUND
Before using RIP, you need to configure basic RIP functions and specify a RIP version. You can run commands to view the configuration results.
NETWORKING REQUIREMENTS
As shown in Figure 3-1, it is required that RIP be enabled on all interfaces of Router A, Router B, Router C, and Router D and the routers interconnect with each other by using RIP-2.
CONFIGURATION ROADMAP
The configuration roadmap is as follows:
1. Configure an IP address for each interface to ensure that neighboring nodes are reachable at the network layer.
2. Enable RIP on each router and configure basic RIP functions.
3. Configure RIP-2 on each router and check information about classless routes.
DATA PREPARATION
To complete the configuration, you need the following data:
Network segment (192.168.1.0) to be enabled with RIP on Router A.
Network segments (192.168.1.0, 172.16.0.0, and 10.0.0.0) to be enabled with RIP on Router B.
Network segment (172.16.0.0) to be enabled with RIP on Router C.
Network segment (10.0.0.0) to be enabled with RIP on Router D.
RIP-2 on Router A, Router B, Router C, and Router D.
PROCEDURE
1. Configure an IP address for each interface. The configuration details are not described here.
2. Configure basic RIP functions.
# Configure Router A.
[RouterA] rip
[RouterA-rip-1] network 192.168.1.0
[RouterA-rip-1] quit
# Configure Router B.
[RouterB] rip
[RouterB-rip-1] network 192.168.1.0
[RouterB-rip-1] network 172.16.0.0
[RouterB-rip-1] network 10.0.0.0
[RouterB-rip-1] quit
# Configure Router C.
[RouterC] rip
[RouterC-rip-1] network 172.16.0.0
[RouterC-rip-1] quit
# Configure Router D.
[RouterD] rip
[RouterD-rip-1] network 10.0.0.0
[RouterD-rip-1] quit
# Check the RIP routing table of Router A.
[RouterA] display rip 1 route
Route Flags: R - RIP, T - TRIP
A - Aging, G - Garbage-collect
-------------------------------------------------------------------------
Peer 192.168.1.2 on Pos1/0/0
Destination/Mask Nexthop Cost Tag Flags Sec
172.16.0.0/16 192.168.1.2 1 0 RA 16
10.0.0.0/8 192.168.1.2 1 0 RA 16
The preceding display shows that the routes advertised by RIP-1 carry natural masks.
1. Configure the RIP version number.
# Configure RIP-2 on Router A.
[RouterA] rip
[RouterA-rip-1] version 2
[RouterA-rip-1] quit
# Configure RIP-2 on Router B.
[RouterB] rip
[RouterB-rip-1] version 2
[RouterB-rip-1] quit
# Configure RIP-2 on Router C.
[RouterC] rip
[RouterC-rip-1] version 2
[RouterC-rip-1] quit
# Configure RIP-2 on Router D.
[RouterD] rip
[RouterD-rip-1] version 2
[RouterD-rip-1] quit
2. Verify the configuration.
# Check the RIP routing table of Router A.
[RouterA] display rip 1 route
Route Flags: R - RIP
A - Aging, G - Garbage-collect
-------------------------------------------------------------------------
Peer 192.168.1.2 on Pos1/0/0
Destination/Mask Nexthop Cost Tag Flags Sec
172.16.1.0/24 192.168.1.2 1 0 RA 32
10.1.1.0/24 192.168.1.2 1 0 RA 32
The preceding display shows that the routes advertised by RIPv2 carry subnet masks.
