Frame-Relay map statement deleted??

[jdl508]

Hello, I have a frame lab that has a 2521 as the frame switch. from there i have a hub and spoke with r2 as the hub and r3, r4 as the spokes. I have 2 questions. I can ping from r4 to r2 and from r2 to r4, but that is it. I thought to remedy the problem I would add this command to each interface on the spoke router and hub router
frame relay map ip x.x.x.x dlci # broadcast

when i added this on the r4 , for example, and add the r3 ip address, it automatically deletes after a min or so . Not too mention it ddoesnt allow me to ping. If anyone has any ideas please let me know. By the way all ip's are in the same subnet.
thanks

Ok, what I would do is put in frame maps on all FR routers (r2-r4)

For instance:

Given the following sample IP addresses:

R2 s0: 192.168.0.2
R3 s0: 192.168.0.3
R4 s0: 192.168.0.4

Using the DLCI on the ff table:

R2 -> R3 123
R2 -> R4 124
R3 -> R2 132
R4 -> R2 142

My Fram map statements would go like this:

R2:
int s0
ip add 192.168.0.2
encap frame
fram-relay map ip 192.168.0.3 123 broadcast
fram-relay map ip 192.168.0.4 124 broadcast

R3:
int s0
ip add 192.168.0.3
encap frame
fram-relay map ip 192.168.0.2 132 broadcast
fram-relay map ip 192.168.0.4 132 broadcast

R4:
int s0
ip add 192.168.0.4
encap frame
fram-relay map ip 192.168.0.2 142 broadcast
fram-relay map ip 192.168.0.3 142 broadcast

When configuring static frame maps, don't forget to turn off inverse-arp using the following commands:

int s0
encap frame
no fram inverse-arp
no arp fram

You will need to reboot the routers to get rid of stubborn dynamic frame maps. Orlando Palomar Jr

huh, I have added the appropriate map statements which now stay thanks to the no inverse-arp cmd. Anyway I still cannto ping router to router. All lines are up, all pvc look good. Im gonna keep working with it. I may just do an erase start and start over again. tghansk for the help

It would help if you post your routers' config on the forum. Orlando Palomar Jr

Sorry about the Delay I will post 4 routers config
the frame switch
2 spokes
1 hub
I have checked the obvious, all pvc's are up and active, all serial / lines are up, i turned invers-arp off so mappings work. I'm thinking i have either a prblem with my dlci statements or the mapping / dlci statements.

Please let me know what you think

You didn't include RTC's config. Anyway, I can see that your FR-switch is messed up. Reconfigure it using the following suggested config: (Remove the old frame-relay route commands first). I suggest that you put RTA on Serial1, RTB on Serial2, and so on to make troubleshooting easy.

interface Serial1
no ip address
description CONNECT TO RTA
encapsulation frame-relay
clockrate 64000
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 112 interface Serial2 121
frame-relay route 113 interface Serial3 131
!
interface Serial2
no ip address
description CONNECT TO RTB
encapsulation frame-relay
clockrate 64000
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 121 interface Serial1 112
frame-relay route 123 interface Serial3 132
!
interface Serial3
no ip address
description CONNECT TO RTC
encapsulation frame-relay
clockrate 64000
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 132 interface Serial2 123
frame-relay route 131 interface Serial1 113


For the DLCI settings, use the following: (Note that I configured the three serial interfaces on the FR-switch as a full-mesh)

R1 -> R2 112
R1 -> R3 113
R2 -> R1 121
R2 -> R3 123
R3 -> R1 131
R3 -> R2 132

Good luck and keep me posted. Orlando Palomar Jr

oj88,
Hello, I really appreciate the help youve given me. Last night I got the frame cloud up and running (properly) and have since attached 3 routers to the cloud configuring ospf as the routing protocol with the
ip ospf network point-to-multipoint
cmd. Well on to multi area ospf now. Again thanks for your help,
thanks
