Frame Relay problem. Can't ping spoke routers

[dean.zimmerman]

I have a home lab setup with 3 routers connected to a 2520 router configured for frame relay. When I set up the hub and spoke using point-to-point I can ping the spoke routers from R1. My problem is when I try to set up the lab using multipoint. The ping just immediately comes back with % Unrecognized host or address, or protocol not running.

I set up the frame map to ping the other two routers but it still doesn't work. Everything shows active:

R1>show frame map
Serial3/0 (up): ip 172.12.123.2 dlci 122(0x7A,0x1CA0), static,
              broadcast,
              CISCO, status defined, active
Serial3/0 (up): ip 172.12.123.3 dlci 123(0x7B,0x1CB0), static,
              broadcast,
              CISCO, status defined, active

R1>show frame lmi

I think I have it set up correct. Obviously not or else I would be able to ping. Any help would be greatly appreciated.

I guess I know your problem..

Your IOS probably wants you to insert the keyword "ip" while pinging.

Try this :

ping ip 172.12.123.2

If you dont give IP keyword then it initiates a DNS querry.

Let me know if it solves your problem.

Hello,

Maybe my question could be obvious but, do you have IPs configured on the interfaces? I cannot see them in your configuration:

R1(config)#interface serial3/0
R1(config-if)#encap frame
R1(config-if)#no frame-relay inverse-arp
R1(config-if)#interface serial3/0
R1(config-if)#frame map ip 172.12.123.2 122 broadcast
R1(config-if)#frame map ip 172.12.123.3 123 broadcast
R1(config-if)#int serial3/0
R1(config-if)#no shut
R1(config-if)#

Cheers

Thank you both for the quick reply. Sometimes it is the obvious. After I did the write erase on all the routers I forgot to configure the interfaces. I need to study earlier in the day. Again, thank you for the help.

Have a look at this configs if you are stuck... This will help you understand the FR config.
