Frame Relay configuration help

I have two sites that I will connect using a fractional 128k frame relay. I am using cisco 2621 routers on both sites with WIC cards in them. I got the DLCI numbers and the LMI type that will be using by the TELCO and I need help in configuring the interfaces.

This is what I have so far. I know I am missing something because I still getting line protocol down.

Router site A

bandwidth 128

ip address 10.10.10.2 255.255.255.0

encapsulation frame-relay

no ip mroute-cache

frame-relay interface-dlci 30

frame-relay lmi-type ansi

Router Site B

bandwidth 128

ip address 10.10.10.1 255.255.255.0

encapsulation frame-relay

no ip mroute-cache

frame-relay interface-dlci 30

frame-relay lmi-type ansi

Thank you in advance for you help!!

Re: Frame Relay configuration help

I assume you are using WIC1-DSU cards in your 2620s -- in other words, full T-1 cards. You need another statement to tell the router's internal CSU that you are using only a fraction of the T-1.

Here is the command:

service-module t1 timeslots 1-2

Put it in on both sides.

Re: Frame Relay configuration help

in case you are not connected to a frame relay device other than Cisco you must use IETF encapsulation by using

ENCAPSULATION FRAME-RELAY IETF

on both sides.

I also recommend you to define IP and DLCI in subinterface rather than defining on physical port.
