Hi Victor,

I posted it already somewhere but here it is again and I threw in a "sh
ver" to humor you. :-) At least in the old days Cisco made router
casings which could withstand a 9mm AP round from 3 meters distance!

Nice output Danny, please can you do a show run interface serial 0
 in R1, Thanks again

Etc.

A search in Google brought me this link to some unknown mailing list
with wannabe CCIEs ;)

Still doesn't really explain why is has this behaviour and if its
normal.

Hello Danny, Please can you send us the debug frame-relay packet output

Thanks

        I notice that R1 and R2 are connected via ethernet. Is this

True. :)

I also could have mentioned that when using FR the default-gateway
command didn't work. Better said, it would probably work if only I could
ping the gateway. Seems to be an encapsulation problem.

R1:
interface Serial0

 cdp enable
 frame-relay interface-dlci 115

R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#no ip routing
R1(config)#ip default-gateway 10.2.3.5
R1(config)#exit
R1#ping 10.2.3.5

Type escape sequence to abort.

To be honest, I don't know why it does that.
