RE: Bridging

[Patrick Lidstone \(Personal E-mail\)]

The header hop=n should be incremented for each traversal of a physical
network. A quick and dirty fix for your bridge would be to not forward
messages with hop>1. Obviously this won't work in situations where you
have more than 2 physical nets.
