Transmission errors in Dynamips?

Hi all,

I've noticed while doing some labs that packets can get corrupted in a
stable topology. For example :

PE1#
*Oct 12 20:29:41.299: %OSPF-4-ERRRCV: Received invalid packet: Bad
Checksum from 172.16.12.2, FastEthernet2/0

I've also seen BGP synchronization errors, where the marker field in a
BGP header wasn't what it was supposed to be. Has anyone else seen this?

Average cpu load on my machine is ~50%, while simulating 8 routers.
