- We have a problem that is maybe related to this ARP bug. The
- situation is a Cisco Router on a LAN connected by DEC bridges to
- other LAN's. The Cisco ARP's packets are only heard on the local cable.
- However, the other machine's ARPs do propagate correctly. What's
- special about CISCO ARP's packets? Anyone have heard about this before?
