steve,
I tried with SMI image..it works fine..
provide a debug ip icmp (want to see if there is encap failures)
just a guess..can you turn off ip routing if you have it enabled

Subject: RE: Mgmt Interface 3550 in separate vlan
I am trying to setup a bridge on a router with an isl trunk to a 3550. I
have been asked to set a management interface on the switch on vlan 40, and
I am trying to bridge via IRB on the router between the switch and the
ethenet, vlan 30. I have no connectivity between the switch and the router.
Here are some configs:
switch:
hostname 3550
!
interface FastEthernet0/12
switchport trunk encapsulation isl
switchport trunk native vlan 40
switchport trunk allowed vlan 10,20,30,40,1002-1005
switchport mode trunk
no ip address
!
!
interface Vlan40
ip address 145.1.36.100 255.255.255.0
!
ip default-gateway 145.1.36.6
ip classless
ip http server
!
end
router:
hostname R6
!
bridge irb
!
interface FastEthernet3/0.30
encapsulation isl 30
no ip redirects
bridge-group 1
!
interface FastEthernet3/0.40
encapsulation isl 40
no ip redirects
bridge-group 1
!
interface BVI1
ip address 145.1.36.6 255.255.255.0
!
bridge 1 protocol ieee
bridge 1 route ip
bridge 1 route ipx
!
end
