I have just installed a 2612 router making a translational
bridging between one Ethernet and one Token-Ring Interfaces
My problem is the following one:
The bridging table is dynamically filled by the router. However, the cisco
router periodically clears the bridging table according the bridge-group
aging time.In my case, it causes communications problem between both LANs: If I ping a station from TR lan to Ethernet LAN, the ping can work correctly a
few minutes (if the station pinged is known by router and is therefore
present in the bridge table). After a few minutes, the ping doesn't work any
more and I notice that the table has been cleared by the router. As my
stations don't move from a network to another one, I would like to avoid
this problem by increasing the aging time to 3600s for example ("bridge 1
aging-time 3600" in config mode). But when I change this timer to 3600,
after a few minutes, the router sets back itself this timer to 15s and the
table is cleared again. It seems impossible to manage this timer and to
avoid a too fast update of the table ?
Does anyone know a solutions/workaround for this problem?
Thanks in advance
Tom
