Fallback Bridging bridges two VLANs together on Cat3550. Check the DOC CD
link below:
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12119ea1/3550scg/s
wfallbk.htm
It is very simple to configure:
Bridge 1 protocol vlan-bridge
!
]nt vlan 1
Bridge-group 1
!
]nt vlan 2
Bridge-group 1
In your example, I suppose R2 port and NETBIOS host port on CAT2 is in
different VLANs. Same problem on CAT2. To solve it, configure fallback
bridging on CAT1 & CAT2.

Subject: Fall-Back Bridging
Hi,
Does anybody know what Fall-Back Bridging is?
I try to understand is ...but i dont quit know how I need to interpret
this...
What is Fall-Back Bridging?
And how do you configure is?
I ran on to this when i was configureing DLSW+
NETBIOS_HOST1------>CAT1------>R1------>R2------>CAT2------>NETBIOS_HOST2
VLAN1
VLAN2
I made a DLSW peering between NETBIOS_HOST1 and NETBIOS_HOST2 both
NETBIOS_HOSTS are connected to a different switch and a diffferent VLAN...
in the explanation of the task they told me to use Fall-Back Bridging ...
But I don't know how ...
Thanks
Iwan
