E0 of R1, R2 and R3 connect to switch.

I configure R3 as irb.

on R1:

int e 0
ip add 192.168.1.2 255.255.255.0

on R2

ip add 192.168.1.3 255.255.255.0

I enable trunk on switchport which connect to r3 with
dot1q encapsulation. The port to r1 in Vlan 2, the
port to R2 in Vlan 3.

Then on R3:

bridge irb

int e 0
no ip add
int e 0.1
encap dot1q 2
bridge-g 1
int e 0.2
encap dot1q 3

bridge 1 protocol ieee

--------------------------------

r1 and r2 can ping each other.

Then on r3, I add:

int bvi 1
ip add 192.168.1.4 255.255.255.0
bridge 1 route ip

But r1 and r2 can not ping 192.168.1.4, why?

Thanks.
