Access within same vlan on ve by router image

[ys]

I connected three 7450 switches with ROUTER image as below. Each switch has ve interface on same vlan as Management.
I can ping from SW1 to both SW2/SW3 and vice versa. But I cannot ping from SW2 to SW3 and vice versa.
How can I configure to communicate each other?
I can reach both switch from different subnet and both switch can go outside.


SW2 [e1/1/1] -- [e1/1/48]SW1[e1/1/47] -- [e1/1/1]SW3



SW1 config
---
vlan 100 name Management
tagg e 1/1/47 to 1/1/48
span 802
router-interface ve 100

int ve 100
ip add 10.100.0.1 255.255.255.0



SW2 config
---

tagg e 1/1/1
span 802

int ve 100
ip add 10.100.0.2 255.255.255.0



SW3 config
---
