bridging problem

Our customer was having the following setup

- core switch 6500 with 5 vlans (1,2,3,4,5)

- protocol used is ospf

- servers and some power users are on vlan 1

findings;

- users on vlan 1 can login to the servers with acceptable response time.

- users on the rest of the vlans (2,3,4,5) login to the servers with very slow response time.

solution;

- enabled fallback bridging on vlans with bridge-group 1. Logging in to the servers became fast and acceptable.

PROBLEM;

With the above solution, we could see all the computers on the network neighborhood. What the administration wants is users must see only computers which belongs to their own vlan.

What will be the solution for this.

Thanks a lot.

Re: bridging problem

Basically with the bridging you are using, you have created one big VLAN. Response times should not be significatly slower using Inter-vlan routing. Maybe you could post the config before you implemented fallback-bridging.

Re: bridging problem

so does it mean that I only have one big vlan now?

Re: bridging problem

Yes since you have essentially just bridged them all together.

Can you post your config so we can see why inter vlan routing is not working.
