Hi,
Can anyone check the following configuration on my Cisco Frame relay switch and 2 end routers, one of the end routers is juniper and the other is cisco. I have given configurations for all the 3 routers.
The problem is that I cannot ping from Router 1(juniper) to Router 2(cisco) or vice versa. I have tried changing the keep alives for all three routers but still it doesnt work.
I have also attached the network diagram indicating all the interfaces just to make it more clearer for you guys


FRAME RELAY SWITCH (CISCO)
===========================
interface Serial1/4
 no ip address
 encapsulation frame-relay IETF
 no keepalive
 clock rate 64000
 frame-relay lmi-type ansi
 frame-relay intf-type dce
 frame-relay route 111 interface Serial1/6 222
!


interface Serial1/6
 no ip address
 encapsulation frame-relay IETF
 no keepalive
 clock rate 64000
 frame-relay lmi-type ansi
 frame-relay intf-type dce
 frame-relay route 222 interface Serial1/4 111



Router 1 (Juniper)
===============
 se-1/0/0 {
        no-keepalives;
        encapsulation frame-relay;
        unit 0 {
            point-to-point;
            dlci 111;
            family inet {
                address 10.1.1.11/24;
            }


Router 2 (Cisco)
==============
interface Serial0/1/0

 no ip address
no keepalive
 encapsulation frame-relay

!
interface Serial0/1/0.1 point-to-point

 ip address 10.1.1.10 255.255.255.0

OK please post the following show commands. "show interface" and "show frame pvc" on the cisco router and on the switch. Also do a show frame-relay map on the router.

Try changing the Juniper like so.
  family inet {

            address 10.1.1.11/24 {

                destination 10.1.1.10;

            }

Open in new window

Also cisco by default does lmi type auot sensing and they favor the cisco type so you may want to hard cose to

        lmi {
            lmi-type ansi;
        }
and for the Cisco

frame-relay lmi-type ansi

oops your doing no keep alives so that shouldn't be an issue but if you do turn keepalives on (which is recommended) hardcode the lmi type.

One last thing not sure if inverse arp is on by default on Juniper so you may want to make sure it's on as you have no farme-relay map statements

unit 100 {
point-to-point;
dlci 111;
lmi {
      lmi-type ansi;
}
inverse-arp
family inet {
address 10.1.1.11/24;{
destination 10.1.1.10;
           }
      }
}

yeah but when I try doing keepalives the line protocol goes down so I have to keep them off.

I tried your configuration for juniper...still I cant ping

lmi-type is configered under serial interface on the Juniper.

Do the show commands so we can see if you have a frame-relay map correct without that you can't ping.

Firstly, can you tell me how can I set inverse arp you mentioned in juniper because when I try to set the inverse arp it gives me error like there is some syntax issue or I dont know....secondly, do you know the command to see frame-relay map in juniper...I am sorry I am really new with Juniper so I dont really know that many commands

By default, inverse Frame Relay ARP is disabled. To configure a router to respond to inverse Frame Relay ARP requests, include the inverse-arp statement at the [edit interfaces interface-name unit logical-unit-number] or [edit interfaces interface-name unit logical-unit-number family inet address address multipoint-destination destination] hierarchy level:

[edit interfaces interface-name unit logical-unit-number]

inverse-arp;

and for the frame-relay map it is the same as a cisco "show frame-relay map"
