Frame Relay EIGRP help???

Robbo777

R1, 2 and 3 aren't seeing each other at all as neighbours, the frame relay point to point connections are able to ping though! Very confusing!

Router3#sho frame-relay map
Serial3/0.301 (up): point-to-point dlci, dlci 301, broadcast, status defined, active
Serial3/0.302 (up): point-to-point dlci, dlci 302, broadcast, status defined, active

I have noticed that there are no dynamic addresses being formed as well. Why and could this be an issue?

Try disabling inverse arp - no frame-relay inverse-arp. May do the trick.

If not, could you post the configuration of your FR switch (if it's a router rather than the switch on GNS3) also make sure the interfaces on your FR router/switch is using the frame-relay intf-type dce command.

Robbo777

Dont you need inverse arp though to make the DLCI's talk?

Also, i cant post the config because its a frame relay cloud in packet tracer. But the DLCI's do communicate because i can ping between them:

102 dlci can ping 201 etc...

They aren't dynamic though which i cant think why! So strange, nothing is straight forward with frame relay haha

Deathmage

I ran into the same problem last night then a quick search on Google showed I need a FR switch, but your config answered something that are confusing me about FR, so Koodos!

They do say once you understand FR it's golden, it's just a matter of getting there that is the *****!!!!!

Robbo777

I have a "frame switch" in packet tracer albeit its not actually a frame switch but just a cloud with frame relay options on it. I wanted to get this working in packet tracer though instead of gns3! I s there any way i can do this or if someone can help me out??

I'm using physical hardware. Do you know your DCE/DTE's?

also not sure but I think FR is a limitation in packet tracer.

Robbo777

Yeah all the DCE's are connected to the "cloud" in packet tracer and the DTE are connected to the routers. Everything SEEMS right! i honestly dont know why its not having it! So frustrating

Mooseboost

Could you post your lab file?

james43026

You don't have EIGRP advertising on your FR wan links. Include the FR interfaces in your EIGRP network statements. Also your frame-relay maps aren't showing an IP address because you have them configured as sub-interfaces in a point to point topology.

Deathmage

I'll be labbing in FR tonight, once I get it working I'll post you the config and hopefully it helps you.

Simrid

You don't need inverse ARP as long as the static routes are configured correctly. Inverse arp allows the routes to be learned dynamically.

Deathmage

@Robo - here is the FR switch that was done in the home-lab I'm using, just modify to your needed. take note of the DCE-DTE ends of the serial connection, the DCE side will need a clock rate.

This frame-switch config was for when I wasn't using OSPF.

I'm using inverse ARP for the FR in the lab but I'm also using multi-area OSPF, I turned OSPF off and indeed inverse arp wasn't needed, so I can contest to this statement. inverse arp is on by default if I remember correctly.

Well with what I remember
1. the reason why they can ping and cant see in neighboring is Frame relay is gonna put the other interface address in the routing table.
2. You did everything but I think you forgot to mention few statements in the eigrp 1 and i guess thats the main problem

router eigrp 1
network 10.10.0.0 0.0.255.255
no auto-summary [\Quote]

**Remember you need to keep in mind why they can ping during troubleshoot if not you dont know why thats happening.
