Frame-Relay Configuration 1

[12122053]

I have 3 routers setup in my lab for testing. One router for the frameswitch and the other 2 are DTE devices(RouterA and B). I followed the serial port FAQ's and the configuration work fine until i power down the routers. I can't ping the serial interface's anymore within router A and B. I was able to ping within all routers before what happened? It seems that the inverse-arp is not working. Any troubleshooting suggestions. Please help, thanks.

Did you save your running config to your startup conf ?
Do a sh ip int brief and check your interfaces. J.Fisher CCNA

All serial interfaces from all 3 routers are up. I do a sh frame pvc all are active. I did save my running conf to startup, thanks jeter any other ideas.

shut them down.. bring up the FR switch first.. then bring up the two "ends" so they can bring up the connection to the "frame switch"

What routing protocol are you running? If ospf than you want:
Frame=Relay Switching
int s1
encap frame-relay
frame-relay intf-type DCE (be sure wiring is right)
frame-relay route 102 interface Serial0 103 (the DLCIs set on the other routers)

int s0
encap frame-relay
frame-relay intf-type DCE (be sure wiring is right)
frame-relay route 103 interface Serial0 102 ( the DLCIs set on the other routers)

on the other two routers:
int sX
encap frame-relay
Be sure your ip address are in the same subnet ie; 10.1.1.2 and 10.1.1.3

This should work! Be sure to copy run start before shuting down the routers. Best wishes

Just got back from vacation. I even whip out config with a new one and still can't ping the serial interfaces on router A and B. I remember when I first set this up it work fine now it doesn't. Also on router B which is a 3620 i can't even ping the ethernet interface. If i do a sh inter e0 states the interface is up, what gives. If i want routers A and B to be able to ping each others ethernet interfaces do I need static routes? Here is my running configs for all 3 routers. Thanks so much who helps

I can't even ping the ethernet interface on router B please any suggestions, thanks alot.

 

[jeter]

looking at the ip addresses of the interface I would make router A 192.168.1.1/24
and router B 192.168.1.2/24.

I see an ip route of 0.0.0.0 0.0.0.0 on the routers however I would put the interface
of the other router ( next hop )

Router A
ip route 0.0.0.0 0.0.0.0 192.168.1.2

Router B
ip route 0.0.0.0 0.0.0.0 192.168.1.1

Make sure all interfaces are up and that you can ping them from the router. Jeter@LasVegas.com

I'm not quite sure what the problem is however I think it may be with the default routes like jeter suggested. I noticed that you are using DDR on the BRI which is triggered with any IP traffic. So maybe when you try to ping, it brings up the DDR link, so traffic is trying to exit out of BRI instead of the serial0 because it has the lower admin dist. of the 2 default routes you declared. I'm kinda lost on your NAT config as well.

All im trying to do is setup a frame-relay lab so I could study for my ccnp with 3 routers. I place ip's on the serial interfaces on router a & b , but I can't ping them from within all 3 routers. Do i need to use the frame-relay map ip command or static routes or routing protocol? Thanks
