Hi list,
I am trying to get STP to work with (to start with) one openbsd firewall
/ gateway and two switches to the same subnet for failover. Let me draw:
-----------------------------------
| Internet |
-----------------------------------
|
---------------------------
| |
| OpenBSD GW |
| |
---------------------------
/ \
-------------- ------------------
| SW 1 | | SW 2 |
|(stp root) | | (stp fallback) |
-------------- ------------------
\ /
\ /
--------------------
| subnet |
--------------------
The openbsd box should act as an IP gateway for the subnet. I bridged
two NICS, one goes into sw1, the other into sw2. I also want to give
this bridge an IP address, but that is not possible. So I
- tried to set a vlan on the bridge, (vlandev bridge0), but this is not
possible ( SIOCSETVLAN: Protocol not supported). The switches see each
other and root sw is elected.
- tried to set a failover trunk on the bridge member interfaces and set
the vlan on that. Packets are being forwarded then, but STP does not work
(switches don't see each other)
How should I go about this?
Thanks,
Arjen.
