Hi
[This is part of IE lab 7]
R5 and R4 is connected via frame relay. I had to run ISIS on these
ckt. Bute R5 is a point to point sub interface and R4 having physical
main interface I had to use a tunnel (I had an old image that does not
support ISIS point to point network type feature ).

Everything was working fine up to the QoS section. Where i had to
enable frame-relay traffic shaping on R4 physical interface (only on
R4). Just after I enabled frame-relay traffic-shaping on r4 my clns
neighborship status gone to INIT. I removed the traffic shapign and
everything is working fine. Then i added the traffic shaping on both
R5 and R4 then everything started working.

is there any relation between frame-traffic shaping and ISIS ?
