Configure a trunk between 4006 and external router, to trunk both the vlans. Configure two subinterfaces on the fast ethernet int. of router one each for each vlan. I assume the vlans in your case as 10 and 20.
The router configurations would look somewhat like this....
int fa0/1.10
encapsulation isl 10
description vlan 10
bridge-group 1
int fa0/1.20
encapsulation isl 20
description vlan 20
bridge-group 1
bridge 1 protocol ieee.
On the port on catalyst connecting to router, configure a trunk using command "set trunk"
Hope that helps!

Hi Sankar Nair,
Thank very much for your support me, and now I have proplem on catalyst 4006 and AT 8324SX Allied Telesyn:
Configuring port on catalyst 4006 using trunk mode and 802.1q encapsulation as below:
interface FastEthernet2/35
switchport trunk encapsulation dot1q
switchport mode trunk
duplex full
no snmp trap link-status
Configuring fastethernet port on AT8324 switch using trunk mode (configure by user graphic interface mode).
But i don't understand, the trunk line didnt work
Can you check configuration on catalyst 4006?
Best regards
Manh Hung

The configs on the cat do look fine.
See if you did give a "no shutdown" on the port fa2/35. (this might not be needed, as "shutdown" is not there under the interface in your configs)
CHeck the trunking status.... Try "show interfaces fastethernet 2/35 switchport" or "show interfaces fastethernet 2/35 trunk "
It could also be a problem with the AT 8324 external router configuration.
02-24-2003 10:48 PM
Thank you very much, i will try follow your recommend.
Hung.

If memory serves me right, the AT switch automatically tags all traffic on the trunk link. The 4006 does not tag the native vlan, which is vlan 1 (by default) in your configuration. Therefore I would not expect vlan 1 to operate between the router and switch as configured. If this is your problem, the solution is to set another unused vlan as the native vlan on the 4006, so that vlan 1 becomes tagged...
interface FastEthernet2/35
switchport trunk encapsulation dot1q
switchport mode trunk
switchport access vlan 999 !!!! vlan 999 is unused
duplex full
no snmp trap link-status
This should provide continuity in vlan 1 between Cisco and AT switches.

To day I go to my factory and configuring Catalyst 4006 and AT8324 follow
your instruction but the trunking line still doesn't work.I changed
configuration as access mode the system work propely.
Pls help me checking my configuration.

Hi there
i am not an expert in networking
but i gusse the problem is the encap mismatch
set both the switch and router to ISL encap
that may aolve the problem
good luck

you just need adding a cross-over ethernet cable to one port belonging to both vlans.....
