I know I've overlooked someting simple (I hope!), but I'm stuck on this
problem:
I'm routing between vlans using a fastethernet interface and ISL
encapsulation. I've set up my vlans on my switch, set up trunking on port
1/1 (connected to my router), and set the router's configuration so that
each vlan is on a subinterface.
But I'm getting this error:
02:03:12: vLAN: Received ISL encapsulated UNKNOWN packet bearing colour ID 1
on interface FastEthernet0/0.1 which is not configured to
route or bridge this packet type.
Here is the router config:
!
interface FastEthernet0/0
no ip address
no ip directed-broadcast
!
interface FastEthernet0/0.1
encapsulation isl 1
ip address 192.168.252.2 255.255.255.0
no ip redirects
no ip directed-broadcast
!

encapsulation isl 2

Here is the switch config
