Description : The lab exercise explains configuring and verifying site-to-site IPSec VPN.
The network topology shown below has three routers. The task is to configure R1 and R3 to support a
site-to-site Psec VPN when traffic flows between their respective LANs. The IPsec VPN tunnel is from R1 to R3
via R2. R2 acts as a pass-through and has no knowledge of the VPN. IPsec provides secure transmission of
sensitive information over unprotected networks, such as the Internet. IPsec operates at the network layer
and protects and authenticates IP packets between participating IPsec devices (peers), such as routers
