IPX and dot1 trunking

Hi, I seem unable to carry IPX over a dot1q trunk connection. I created a sub-interface for each VLAN (default anfd new) on a FA interface on a 3640 router. Previously there was just the FA interface withno sub-interfaces. The new VLAN works fine, I have no troublw with IP but had no connectivity to the data center using IPX. If I delete the sub-interface for VLAN1 and take dot1q trunking off the sub-interface for the new VLAN, IPX works.

Re: IPX and dot1 trunking

Does the sub interfaces have the ipx network command ?? Can you post a sample of your config ?

Re: IPX and dot1 trunking

I had to clear the config to get the site back in production but it lookid like this

Interface FA0/0

duplex auto

speed auto

int fa0/0.100

des vlan 55

ip adress 172.16.55.1 255.255.255.0

encap dot1q 55

int fa0/0.200

des vlan1

ip address 172.16.50.1 255.25.254.0

ipx network 5

ipx encap dot1q 1 default

the vtp server is a 2948, 8 other vtp clients a mix of 2948,2950 and 3524xl. All switches are trunked (dot1q) over Gige ports.
