Redundant Bridging and STP
I have 2 OpenBSD, every one has few Ethernet interfaces,
and I want to create two ethernet connection between them, as two link between two switches: BSD TEST-A em0 <--------> em0 BSD TEST-B BSD TEST-A em1 <--------> em1 BSD TEST-B device TEST-A: test-a /etc>cat hostname.em0 inet 10.10.10.1 255.255.255.0 NONE up test-a /etc>cat hostname.em1 up test-a /etc>cat hostname.bridge0 add em0 add em1 blocknonip em0 blocknonip em1 stp em0 stp em1 up test-a /etc> device TEST-B: test-b /etc>cat hostname.em0 inet 10.10.10.2 255.255.255.0 NONE up test-b /etc>cat hostname.em1 up test-b /etc>cat hostname.bridge0 add em0 add em1 blocknonip em0 blocknonip em1 stp em0 stp em1 up test-b /etc> So, if one link is out of function, then traffic will pass throuhtg anohter one. But it is not working, if: test-a /etc>ping 10.10.10.2 is working on em0, until: test-a /etc>ifconfig em0 down then pinging stops, it seems RSTP is not working, i.e. traffic is not translated on em1-em1 link. any idea? |
