Question for Frame-relay posted 03/28/2006
[Chronological Index] [Thread Index] [Top] [Date Prev][Date Next] [Thread Prev][Thread Next]


Guys -

Below is my configuration fro frame-relay and I was wondering if you can
figure out what's wrong. For some reason one spoke will ping consistently to
the hub on both addresses but not the other spoke. The other spoke will in
turn only get every other ping through. I don't understand what I'm doing
wrong and wondering if you guys can help.

 

Router 2 hub:

 

interface Serial0/0

no ip address

encapsulation frame-relay

!

interface Serial0/0.1 point-to-point

ip address 1.1.2.1 255.255.255.0

frame-relay interface-dlci 203

!

interface Serial0/0.2 point-to-point

ip address 1.1.2.2 255.255.255.0

frame-relay interface-dlci 204

 

Router 4 Spoke:

 

interface Serial1/0

ip address 1.1.2.4 255.255.255.0

encapsulation frame-relay

frame-relay map ip 1.1.2.1 402 broadcast

frame-relay map ip 1.1.2.2 402 broadcast

frame-relay map ip 1.1.2.3 402 broadcast

frame-relay map ip 1.1.2.4 402

no frame-relay inverse-arp

 

 

Router 3 Spoke:

 

interface Serial1/0

ip address 1.1.2.3 255.255.255.0

encapsulation frame-relay

frame-relay map ip 1.1.2.1 302 broadcast

frame-relay map ip 1.1.2.2 302 broadcast

frame-relay map ip 1.1.2.3 302

frame-relay map ip 1.1.2.4 302 broadcast

no frame-relay inverse-arp
