MAJOR HELP with Frame Relay network

DRIVING ME NUTS!!
Been at this for 2 days and through searching this forum as well as watching the Chris Bryant video over and over.

okay so it appears that i "supposedly" have my frame relay network set up correctly as interfaces are up and protocol is up.

i am trying to ping from r2 to r3 and vice versa with no luck. some help please

3 routers

R1
interface Serial0
no ip address
encapsulation frame-relay
no fair-queue
clockrate 64000
no frame-relay inverse-arp
frame-relay map ip 172.16.123.2 122 broadcast
frame-relay intf-type dce
!
interface Serial1
no ip address
encapsulation frame-relay
clockrate 64000
no frame-relay inverse-arp
frame-relay map ip 172.16.123.3 123 broadcast
frame-relay intf-type dce

Now the settings for the other 2 routers:

R2
interface Serial0
ip address 172.16.123.2 255.255.255.0
encapsulation frame-relay
no fair-queue
frame-relay map ip 172.16.123.3 223 broadcast
no frame-relay inverse-arp

R3
interface Serial1
ip address 172.16.123.3 255.255.255.0
encapsulation frame-relay
frame-relay map ip 172.16.123.2 322 broadcast
no frame-relay inverse-arp

R1#sh frame map
Serial0 (up): ip 172.16.123.2 dlci 122(0x7A,0x1CA0), static,
broadcast,
CISCO, status defined, active
Serial1 (up): ip 172.16.123.3 dlci 123(0x7B,0x1CB0), static,
broadcast,
CISCO, status defined, active

R1#sh frame pvc

PVC Statistics for interface Serial0 (Frame Relay DCE)

DLCI = 122, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0

input pkts 0 output pkts 0 in bytes 0
out bytes 0 dropped pkts 0 in FECN pkts 0
in BECN pkts 0 out FECN pkts 0 out BECN pkts 0
in DE pkts 0 out DE pkts 0
pvc create time 02:10:06, last time pvc status changed 00:04:05

PVC Statistics for interface Serial1 (Frame Relay DCE)

DLCI = 123, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial1

input pkts 0 output pkts 0 in bytes 0
out bytes 0 dropped pkts 0 in FECN pkts 0

frame relay switching is set on R1

networker050184

Are you trying to set up R1 as a frame switch or just do back to back frame relay links?

uneeqstylezz

basically I am trying to do the Hub and Spoke with R1 being the Hub and R2 and R3 as the spokes.

networker050184

I got that part, but you need to either make R1 a frame switch or make it a regular router with back to back frame relay set up. Right now you have a hybrid of the two which will not work.

uneeqstylezz

hmmm.. i want the R1 to be a frame switch with r2 and r3 having to go through R1 for passing any frames.
my R1 is not set up correctly as a frame switch?

networker050184

Nope. You need to set up frame routes for that.

thank you!! that looks good! i will make fix my configs up and see how that goes. i saw the frame route quite often but following a lab, i could not distinguish as to why i saw frame map and frame route. any info you can expand on that?

networker050184

You can assign a dlci to an interface (frame-relay interface-dlci), map an IP to a dlci (frame-relay map ip), or set up a router to be a frame switch and switch frames - (frame-relay route).

thank you again!! i was finally able to get R1 to be a frame-relay switch with the DLCI Usage=Switched. I am now able to ping from R2 to R3 and vice versa!
now i will try making a regular router with back to back frame relay set up. if you have any tip on that, it would be greatly appreciated.

networker050184

You pretty much just take R1 out of the scenario and turn keepalives off.

thanks! so what i did with this same current setup, i added RIP to the frame relay network. enabled rip on the 2 routers.

im assuming RIP is working correctly right?

i did a show ip route on both routers and the results are different:

R2:

2.0.0.0/32 is subnetted, 1 subnets
C 2.2.2.2 is directly connected, Loopback0
R 3.0.0.0/8 [120/1] via 172.16.123.3, 00:00:14, Serial0
172.16.0.0/24 is subnetted, 1 subnets
C 172.16.123.0 is directly connected, Serial0

R3:
R 2.0.0.0/8 [120/1] via 172.16.123.2, 00:00:20, Serial1
3.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 3.3.3.3/32 is directly connected, Loopback0
R 3.0.0.0/8 [120/2] via 172.16.123.2, 00:00:21, Serial1
172.16.0.0/24 is subnetted, 1 subnets
C 172.16.123.0 is directly connected, Serial1

and then I ran show ip route rip and get these results which look different:

R3#sh ip route rip
R 2.0.0.0/8 [120/1] via 172.16.123.2, 00:00:19, Serial1
3.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
R 3.0.0.0/8 [120/2] via 172.16.123.2, 00:00:19, Serial1
R3#
R2#sh ip route rip
R 3.0.0.0/8 [120/1] via 172.16.123.3, 00:00:03, Serial0
R2#

If you are getting RIP routes (the ones with the R next to them) then it looks to be functioning correctly. The output of those commands looks different because one is showing all routes and one is just showing RIP routes.

thanks! i must say after i read chapter 13 and 14 of the Odom book...frame relay is soooooo much more easier!
