Guys,
Can some one guide me to get dot1q trunk between a cat4507
and nortel baystack 450T to work?
I have configured 2 vlans(untagged members) on nortel box
and getting a 4507 to route between these 2 vlans. The
802.1q trunk is shown as up and trunking on cisco switch
but am not able to get the routing between these two vlans
in place.

Cisco config:
interface FastEthernet3/27
 description link to switch f07
 switchport trunk encapsulation dot1q
 switchport mode trunk
 load-interval 30
interface Vlan1
 ip address 172.16.100.1 255.255.255.0
!
interface Vlan20
 ip address 172.16.20.10 255.255.255.0
!
interface Vlan21
 ip address 172.16.21.10 255.255.255.0
-----------------------------------------------

L3#sh int fa3/27 trunk

Port Mode Encapsulation Status Native

Any help is highly appreciated.
