Hello,
It's a bit of a long mail but i really cannot find the point.
Here is the design :
R1(eth)---(eth)R3(serial 1)--------------(serial 1)R2(token 0)
(serial 0)
|
|
frame relay
I installed :
On r2 serial 1 and token 0 in the bridge-group 1
On r2 a IRB with BVI 1
The aim is to bridge IPX between serial 1 and token 0
and to route IPX this two with BVI 1.
IP is always bridged.
As you will see in the text below IPX is send by BVI 1
IPX paquets are received on the serial 1 but not relayed to the BVI 1
interface.
I use IOS IP/IPX/DEC 12.0.20 (before i was using 12.0.8)
(*R2 configuration *)
version 12.0
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
