Line protocol on routers going up and down for every 10 sec in frame-relay and EIGRP configuration

Hello,

I have implemented a frame-relay hub and spoke topology in GNS3

Topology- HUB s0/0-->FRS s0/0
                  SPOKE1 s0/0-->FRS s0/1
                  SPOKE2 s0/0-->FRS s0/2

Scenario- One hub router and two spoke routers. For Frame-relay switch i have used a router.

Issue- when i configured EIGRP on hub and spoke routers, serial interfaces of hub and spoke routers which are connected to frame-relay switch are going                  up and down, I mean they are not stable- line protocols are going down, interfaces are going down, neighbors are going down for every 5 sec.

I am unable to troubleshoot, someone please help me out. I am attaching configs and outputs of routers for your reference.

Hello,there is a lot of

Hello,

there is a lot of unnecessary configuration I'd remove:

Hub:
interface Serial0/0
 ip address 172.16.124.1 255.255.255.248
 encapsulation frame-relay
 no ip split-horizon eigrp 25
 no frame-relay map ip 172.16.124.2 102 broadcast
 no frame-relay map ip 172.16.124.3 103 broadcast
 no frame-relay interface-dlci 102
 no frame-relay interface-dlci 103

Spoke 1:
interface Serial0/0
 ip address 172.16.124.2 255.255.255.248
 encapsulation frame-relay
 ip split-horizon eigrp 25 ! A spoke is not a hub!
 no frame-relay map ip 172.16.124.1 201 broadcast
 frame-relay map ip 172.16.124.3 201 ! just for spoke-to-spoke connectivity, if needed
 no frame-relay interface-dlci 201

 

You're soley using main-interfaces, so you don't need to configure an interface-DLCI. DLCIs learned by LMI are assigned to the main interface by default.

InARP is enabled (by default), so static IP-to-DLCI mapping is (if at all) only needed for the spoke-to-spoke connetivity on the 172.16.124.0 segment, if this is of importance. The broadcast-keyword is normally not needed in this case, because EIGRP won't form a neighborship as the spokes are not directly connected (spoke-to-spoke traffic has to be send through the hub). Main-interfaces support (pseudo-)broadcast by default.

With this simple configuration, the show frame-relay lmi, -pvc and -map commands should provide a much easier troubleshooting as well.

Hello RolfEven though your

Hello Rolf

Even though your suggestion is valid  I don't think it is a desired solution as this can assign unwarranted dynamic dlci mappings which can have effect on multicast and broadcast traffic.

If eigrp is to be used with multipoint FR , then static mapping I believe is the suggested process with inverse arp disabled and the broadcast key applied to the static mapping for eigrp multicast 224.0.0.10 traffic to traverse the link.

Lastly In my previous post I have suggested to use eigrp unicast for a much cleaner peering so no spoke to spoke eigp peering can occur dynamically when spoke to spoke mappings are in use..

Please don't forget to rate any posts that have been helpful. Thanks.

Hello Paul,thanks for your

Hello Paul,

thanks for your comment. I would agree on using static mappings and unicast peering is the better solution, especially from a security-perspective.

However, I had the feeling that main problem in the original posting was understanding the impact of the frame-relay interface-dlci and the frame-relay map commands on different interface types, so I tried to focus on that.

So I'd like to add some possible changes in the original setup to see what those commands are good for:

On Spoke-1, we could use a point-to-point subinterface instead of the main-interface:

interface Serial0/0
 no ip address
 encapsulation frame-relay
!
interface Serial0/0.201 point-to-point
 ip address 172.16.124.2 255.255.255.248
!

Problem:

Incomming frames are still assigned to the main-interface:

Serial0/0: FR ARP input
datagramstart = 0x7A01C4E, datagramsize = 34
FR encap = 0x30910300
80 00 00 00 08 06 00 0F 08 00 02 04 00 08 00 00
AC 10 7C 01 18 61 00 00 00 00 01 02 00 00

Solution:

Sp2(config)#int s0/0.201
Sp2(config-subif)#frame-relay interface-dlci 201

Serial0/0.201: FR ARP input
datagramstart = 0x7A01B0E, datagramsize = 34
FR encap = 0x30910300
80 00 00 00 08 06 00 0F 08 00 02 04 00 08 00 00
AC 10 7C 01 18 61 00 00 00 00 01 02 00 00
Serial0/0.201: inarp received on 201

%DUAL-5-NBRCHANGE: IP-EIGRP(0) 25: Neighbor 172.16.124.1 (Serial0/0.201) is up: new adjacency

-------------------------------------------------------------------------------------------

The other subinterface type is Multipoint, this would apply to the hub:

interface Serial0/0
 no ip address
 encapsulation frame-relay
!
interface Serial0/0.1 multipoint
 ip address 172.16.124.1 255.255.255.248
 no ip split-horizon eigrp 25
!

But: Same problem as above.

Serial0/0: FR ARP input
datagramstart = 0x7B631AE, datagramsize = 34
FR encap = 0x18710300
80 00 00 00 08 06 00 0F 08 00 02 04 00 08 00 00
AC 10 7C 03 48 D1 00 00 00 00 01 02 00 00
Serial0/0: inarp received on 103

We could solve that the same way, but we could also use static mappings:

interface Serial0/0.1 multipoint
 ip address 172.16.124.1 255.255.255.248
 no ip split-horizon eigrp 25
 frame-relay map ip 172.16.124.2 102 broadcast
 frame-relay map ip 172.16.124.3 103 broadcast
!

Now, the initial sending of InARP-request is disabled, but incomming request will still be answered. This would also be the case when the frame-relay map command is applied on main-interfaces.

So we have 3 different configurations now and the output of the show frame-relay map command is slightly different for all of them:

Hub:

Serial0/0.1 (up): ip 172.16.124.2 dlci 102(0x66,0x1860), static,broadcast, CISCO, status defined, active

Spoke-1:

Serial0/0.201 (up): point-to-point dlci, dlci 201(0xC9,0x3090), broadcast status defined, active

Spoke-2:

Serial0/0 (up): ip 172.16.124.1 dlci 301(0x12D,0x48D0), dynamic, broadcast,, status defined, active

Hello

For hub& spoke eigrp try using unicast peering instead of multicast

 

.HUB

router eigrp 25
neighbour 172.16.124.1 serial0/0
neighbour 172.16.124.3 serial0/0

 

Spokes

router eigrp 25
neighbour 172.16.124.2 serial0/0
