Hey Jongsoo,
It's good to hear from you. I hope you're doing well. As for me, I'm
working through the new IE practice labs as you can see.
At the moment, I'm working on labs for which the Solutions haven't as yet
been posted.
I considered using Fallback Bridging to fulfill this task but I can't see
how to use it as there are no L3 Cat ports involved in this config.
Fallback Bridging requires that L3 ports be put into a bridge-group. In
this scenario, I could make the port connecting rtr-1 or rtr-2 a L3 port but
what about the trunk connecting the 2 Cat's?
If you have any ideas, please show me what you would configure.
Thanks, Tim

How are you doing. Tim?
if all you have to do is to make vlan 20 and 2 communicated in layer 2,
I think you need to configure Vlan-bridge in either CAT 1 or CAT2 .

Hi guys,
I'm trying to figure out how to configure this. I think dot.1q is the way
to go but I can't test this with the equipment I have.
rtr-1 ------------- Cat-1 --- Cat-2 ----------------- rtr-2
.2 < vlan 2 > < vlan 20> .254
| < 192.10.1.x/24 >|
802.1q trunks have been configured between the 2 3550's and both Cat's have
their system mtu set as 1504.
I've configured each cat port connecting the rtr's as follows:
Cat-1
interface FastEthernet0/2
switchport access vlan 2
switchport mode dot1q-tunnel
no ip address
no cdp enable <- added by default
spanning-tree bpdufilter enable <- added by default
Cat-2
interface FastEthernet0/24
switchport access vlan 20
switchport mode dot1q-tunnel
no ip address
no cdp enable
spanning-tree bpdufilter enable
With the rtr's I'm using I can't configure 802.1q trunking on the ethernet
ports connected to the Cat's. And, when I put the ip addr on the phy int,
pings don't work from rtr-1 to rtr-2.
Am I approaching this problem correctly? If I were able to configure the
ethernet ports with 802.1q trunks, would this work?
TIA, Tim
