Frame Relay with ISDN Backup
Objective:
To learn how to configure a network that uses a frame relay connection for its main
network traffic and an ISDN line for redundant backup using floating static routes.
Tools and Materials:
(3) routers
(1) MERGE ISDN emulator
(2) workstations
(2) straight-through cables
(2) DCE-to-DTE cables

Router Patrice Williams
S0/0 192.168.1.1/24 192.168.1.2/24
BRI0/0 10.0.0.1/8 10.0.0.2/8
Loop0 1.1.1.1/8 2.2.2.2/8
Step-By-Step Instructions:
1. Make a router into a frame relay switch.
2. Configure the basics on each router.
3. Configure the loop back networks on each router.
4. Configure the serial interfaces on each router for frame relay.
5. Pick a routing protocol and advertise the networks.
6. Check the frame relay network connectivity. Use ping and trace route.
7. Disconnect/shut-down the frame relay connection.
8. Configure the ISDN BRI0/0 interfaces on each router. Be certain to advertise
the networks.
9. Check the ISDN network connectivity. Use ping and trace route.
10. Set up the ISDN circuit as a back up network using floating static routes. Set
your ISDN connection to time-out after 20 seconds.
