Virtual Private Network (VPN) Example

VPN features let MSOs and ISPs offer private network connections to telecommuters and other
business-oriented customers. In the configuration example that follows, a VPN is set up between two
termination points:
•
•
To properly transmit and receive encrypted/decrypted traffic, each peer in the VPN must activate
Tip
encryption/decryption and have matching access key strings.
The Cisco uBR7200 series allows encrypted traffic to pass over the cable network (and often the
Note
Internet) from one peer to the other, based on a routing table setup in its configuration file.
