All,

I got a strange question on ipx/FR. Here is my scenarios:

R2/s0--302--dlci--203--s0/R1/s0--204--dlci--402--s0/R3

Here is the config for R1, R2 and R3:

R1:

I can have full ip connectivity inside the FR cloud. I can ping from
anywhere to anywhere to/from R1, R2 and R3's serial interface.

In terms of IPX, I can not ping from R3's serail0 to R2 serial 0, but I can
ping from R2's serial 0 to R3's serial 0 and loopback 0. From R1(hub), I can
ping both R2 and R3's serial 0 and loop0.

When I ping from R3 to R2 thru R1, I got the following debug info by doing
"debug ipx packet" on both R3, R2 and R1:

R3#ping 123.2222.2222.2222

debug info:

It seems that R2 got the echo and sends the echo reply to R3 through R1, but
why R3 did not get it?

Please help me with this.

Thanks,

Hans
