Hi
I'm having a L2L VPN connection through internet between LAN A and B. LAN C is connected to LAN B through a router.
How can I make LAN C access LAN A through the same VPN tunnel?
I've attached a design pdf file. Please help me on that.

Yes, you can. You would need to add the LAN C in the crypto ACL on the VPN tunnel between A and B.
On A:
- On the same crypto ACL for LAN A to LAN B, add another line that says from LAN A to LAN C.
On B:
- On the same crypto ACL for LAN B to LAN A, add another line that says from LAN C to LAN A
If you have NAT exemption configured, you would also need to configure the additional ACL to deny NAT between LAN A to LAN C and vice versa on the other side.
Lastly, LAN C and the router between LAN B and LAN C need to route the LAN A subnet towards ASA.
Hope that helps.
