Hi,
Since I did not know what "fallback bridging" was, I looked it up on the
web. Unfortunately, the more I look, the less I seem to grasp it.
What I understand is that it can be used to bridge NON IP packets
between VLANs on a switch.
What I do not understand is how this would work "spanning-tree" wise.
Some literature seems to refer to a "VLAN spanning tree protocol" which
would be something different from the standard IEEE spanning-tree
protocol. Never heard of that. Is this correct, and what would be the
fundamental differences?
Second, to understand this technology better, I started a little
experiment. I did this on cat4:
bridge irb
bridge 3 protocol vlan-bridge
bridge 3 route ip
interface Vlan2200
no ip address
bridge-group 3
!
interface Vlan2300
no ip address
bridge-group 3
!
interface BVI3
ip address 150.100.81.4 255.255.255.0
!
Also I gave R8 and R9 IP addresses: 150.100.81.8 and 150.100.81.9.
Then I tried to see if I could ping R8, R9 and CAT4; but none of it worked.
I assumed that by routing IP on the bridge that R8 and R9 would be able
to see each other; but they are not even able to ping the switch BVI
address.
Should this work or not?
Regards,
Frank
