    Hi Community,

    I have deployed a Branch Getway and VPNC in our Office. I can see VPNC directly connected VLANs advertised in-branch gateway and branch routes in VPNC as Overlay route. But I can't reach the devices in that network from the branch network.

    most likely the IP addresses that you are trying to ping from your branch vlans have a default gateway that is not the VPNC.

    Branch Gateway VLAN interfaces default gateway is in the Branch Gateway. So how should it create Access VLANs in Branch Gateway

    I mean the default gateway for the IP addresses that reside in head end where VPNC is installed.

    What is teh default gateway for those IP addresses? is it the VPNC?

    Branch VLAN  (vlan40) default gateway is in the branch gateway interface. VPNC VLAN (vlan20)   default gateway is in the VPNC interface.

    Can you share a network diagram of the connectivity you're working with?

    so basically your ping from 172.16.20.50 to 192.168.40.x fails?

    if this is a test setup ensure branch gateway is not directlly connected to VPNC (as you have it in your diagram), have a clear layer3 separation.

    By directly connecting VLAN 200 we tried to demonstrate Layer 2 MPLS VPN connection.

    can you ping from the BGW with VLAN 40 as source  to VPNC's VLAN 20 interface?
