Hello,
I have recently replaced a Lancom router with a RB2011 and, after some studying of the wiki, have successfully managed to migrate all functionality. The migration was done in 3 hours and involved multiple VLANs, Gateways, load balancing and QOS. At this point I’m quite impressed with the product and will surely recommend it.
One thing though confused me (without it I would have only needed 2 hours), and I hope somebody can explain this behaviour to me:
At the beginning I had the following situation:
ether1->WAN
DHCP client
ether2->VLAN1-3 (without master)->external SWITCH set to trunk
VLAN1 192.168.1.0
VLAN2 192.168.2.0
VLAN3 192.168.3.0
ether3->directly switched (no master) without VLAN->Client plugged in directly
192.168.1.0
My intent was to use ether3 as fallback if I make a mistake with VLAN configuration and cannot reach the RB anymore.
But even though ether3 was down (not plugged in), it was being used in the routing table, showing as preferred out interface for the network 192.168.1.0. Connecting to the RB from VLAN1 did not get any response because the RB tried to answer through ether3. It became weird when trying to connect to the gateway from VLAN1. The RB switched routes every few seconds. Running two pings, one to the VLAN1 interface, one to 8.8.8.8 resulted in only one working - the working one switching every few seconds.
So, my question is, what am I missing? I had expected that ether3 will be removed from the routing table if down, but this didn’t happen.
