Non-root to non-root traffic

We are looking to connecting 3 networks together using BR350 bridges in the following configuration.

Network A (root) -- Network B (non-root) -- Network C (non-root)

During testing we see good throughput from A<->B and A<->C but it is cut in half for B<->C. The wireless sniffer shows the B<->C traffic is being repeated by the root bride. Since traffic is interchanged between all networks somewhat evenly, this is an undesirable condition.

Is there a configuration or parameter on the bridges to overcome this repeating of the B<->C traffic?

Re: Non-root to non-root traffic

Hi Brian,

This is normal behaviour.

Think of it like a HUB and spoke network everything must go through the HUB before it can go back out to a remote site.

The only way to prevent this behaviour is to have a point to point network to all sites ie.

A <---> B

A <---> C

C <---> B

Each being a pair of bridges as a root and non root
