Subject: IRB problem

Hello all,

This mesaage has parts of my config from CCBootcamp lab 8, so if you haven't
done it yet and don't want to see some answers(or possibly incorrect answers
hehe)to problems in 8a, don't read this!!

I'm on the IPX section of CCBootcamp Lab 8b and I am having an odd problem
with IRB on R5. This is what the topology looks like:

BVI1-[R5]-S1------S5/0-[R1]-FA4/1/0------FA2/0-[R7]-FA2/1
IPX 700 Bridged IPX 700 IPX 701

the bridge tables on r5 and r1 look correct and when I do a IPX ping the
bridge counters on R1 are incrementing in both directions, R7 sees the ping
packets and replies, r1 forwards the reply, but I never see the reply on R5.
a show IPX traffic on r5 reveals I am getting format errors inbound on r5.
I am using the same IPX encap type on r5 and r7. any ideas? could this be
an IOS problem?

r5#sh ipx traf
System Traffic for 0.0000.0000.0001 System-Name: r5
Rcvd: 230 total, 319 format errors, 0 checksum errors, 0 bad hop count,
