I designed birdge with 3 ethernet interfaces, enabled STB on every
interface. Every interface send STP packets periodically.
But when I use the bridges to internetwoking, seems the STP doesn't prevent
broadcast storm in loop connnection.
Network topology like below(no loop), it works well.
H U B Bridge0 Bridge1 Device
| | X eth0 eth1 eth2 eth0 eth1 eth2 ethx
| | | | X X | | |
PC---| |----| |---------------| |-----|
Network topology like below(Hub,Bridge0,Bridge1 generate a loop), it
doesn't works.
H U B Bridge0 Bridge1 Device
| | | eth0 eth1 eth2 eth0 eth1 eth2 ethx
| | | | | X | | | |
PC---| |-|--| |----------|----| |-----|
|------------------|
Packet keep being regenerated and going in the loop until I break the loop.
Any ideas?
Thanks in advanced.
