Welcome to part 2 of this series of video labs. Continuing on from Part 1 - Configuring the Cisco 3640 Router as a Frame Relay Switch. I'll now show you how to configure frame relay on the other routers in the lab. This lab will consist of a hub router which in this case is R3 and two spokes.

The network:

Configuration Video:

To configure the routers for frame relay you must:

• Set the encapsulation type to frame-relay.
• Give the each routers interface that will be used in the frame relay network a unique IP address.
• Configure frame relay map statements.

Below is the configuration for completing this lab. You can also watch the video.

Once you've finished configuring the routers it's time to verify we have connectivity. To do this we ping from R1-R2 and R2-R3, if everything is working as it should be we will see 100% success for our tests.

R2#ping 172.16.1.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.3, timeout is 2 seconds:
