bug ,,? eh ? I dont think so ..

Even on real routers when u have more than one NM-16ESW .. u might (
in fact u will ) face issues in pinging .
This will b there if u have not STACKED the NMs together using  clis
and externa cable ,

On dynamips .. u cannot bring stacking up .. hence not pinging ..
hence use only 1 NM-16ESW

Thnx
