vEdge router - inter VLAN ICMP

Level 1

I created two sub-interfaces on vEdge router - ge0/1.10 and g0/1.11.  They are in the same VPN.

ge0/1.10 has IP address 10.1.10.1 (VLAN 10)

ge0/1.11 has IP address 10.1.11.1 (VLAN 11)

 

I have ge0/1 connect to a Cisco layer 2 switch as a trunk port.  It's a "router on a stick" configuration.

 

I have computers connect to the L2 switch VLAN 10 (PC1) and VLAN11 (PC2) and set their default GW to the corresponding vEdge IP (10.1.10.1 and 10.1.11.1).

 

Here's my observation:

1) PC1 in VLAN 10 can ping both VLAN GW (10.1.10.1 nd 10.1.11.1)

2) PC1 in VLAN 10 cannot ping PC2 in VLAN 20.

3) Return code is "ICMP type:3, code:3, Destination port unreachable"

4) If PC1 in VLAN 10 tries to ping a non-exist endpoint in VLAN 20, it gets a different return code.

 

Based on the above, it looks like vEdge router is purposely blocking ICMP across VLANs.  Is there any way to enable that?  Thanks!
