Umit,
I just tried bridging on a trunk with ISL. As you said, I couldn't get
simple bridge to work easily and I don't have the time to spend playing with
it, but I easily did IRB as follows:
ROUTER1
int Fast 0/0
no ip addr
no shut
int Fast 0/0.1
encap isl 1
bridge-group 1
no shut
int Fas 0/0.2
encap isl 2
bridge-group 1
no shut
int Fas 0/0.4
encap isl 4
bridge-group 1
no shut
int Fas 0/0.725
encap isl 725
bridge-group 1
no shut
bridge 1 protocol ieee
bridging irb
int BVI1
ip address 132.173.1.1 255.255.255.0
SWITCH
vlan 1
vlan 2
vlan 4
vlan 725
int Fas 0/1
switchport mode trunk
no shut
int Fas 0/2
switchport access vlan 2
int Fas 0/3
switchport access vlan 4
int Fas 0/4
switchport access vlan 725
int VLAN1
ip addr 132.173.1.2 255.255.255.0
ip route default 132.173.1.1
ROUTER3 (connected to switch port 0/2)
int e 0
ip addr 132.173.1.3 255.255.255.0
ROUTER4 (connected to switch port 0/3)
int e 0
ip addr 132.173.1.4 255.255.255.0
ROUTER5 (connected to switch port 0/4)
int e 0
ip addr 132.173.1.5 255.255.255.0
Everyone could ping everyone else. You can probably get it to work without
IRB if you have the time to play with it.
Regards,
Kym
