CHAPTER 6
Managing Tunnel-Service and
IPSec-Service Interfaces
This chapter describes how to configure tunnel-server ports, tunnel-service interfaces,
and IPSec-service interfaces on E Series Broadband Services Routers.
This chapter contains the following sections:
•
Tunnel-Service and IPSec-Service Overview on page 207
• Tunnel-Service Interface Platform Considerations on page 209
• Redundancy and Interface Distribution of Tunnel-Service Interfaces on page 212
•
Tunnel-Service Interface Considerations on page 215
•
Configuring Tunnel-Server Ports and Tunnel-Service Interfaces on page 217
• Monitoring Tunnel-Service Interfaces on page 221
Tunnel-Service and IPSec-Service Overview
Tunnels provide a way of transporting datagrams between routers that do not support
the same protocols. Often, these routers are separated by networks.
To configure tunneling, you must identify the tunnel-server ports that reside on modules
that support tunnel services. You can then assign the tunnel-service interfaces that
encapsulate protocols and enable them to be tunneled across the network.
Figure 13 on page 207 displays the interface stacking for tunnel-service interfaces on a
tunnel-server module.
