DHCP from Frame Relay???

[silver1386]

I'll try to explain this. Please let me know if you need further explanation.

At our central location we have a Cisco 3600. We connect our Branches 17, 1, and 29 through a frame relay. At each branch we have a Cisco 1700 router. The individual computers are set up with static IP address. The C.I.O. believes that it is necessary to use static IP addresses because of the frame relay.

My question is this; please tell me if I'm wrong. We can use DHCP on these individual computers because they are connecting to the frame relay through the Cisco 1700, right?

thanks!
Andy

I have not spent to much time with Frame relays, so correct me if Im wrong... The Frame Relay doesnt assign or even use IP addresses, it is the "job" of the Local router to do that. As the router makes the connection back to the frame relay.

But, this does not mean that the IP's need to be static. I can't see any reason why a frame relay would require it... Other than priority.

Floating Static Routes
When the router makes routing decisions, static routes normally take precedence over learned routes. If you have configured static routes, the routerr usually sends data over these routes before using routes that it has learned and stored in the routing table.

However, when the ISDN line is used as a backup connection and is configured with static routes, the primary WAN connection (the Frame Relay line) does not come back up once the ISDN line is used. Floating static routes enable the ISDN line to use static routes to the central-site router until the main WAN connection, the Frame Relay line, is active again.
