1.3 Configuring the Tunnel Interface
This section describes how to configure the tunnel interfaces. These tunnel interfaces are applied
to the GRE tunnels and MPLS TE tunnels.

1.3.1 Establishing the Configuration Task
Applicable Environment
GRE tunnels and MPLS TE tunnels use virtual tunnel interfaces to forward data. Before using
these tunnels, you need to create tunnel interfaces.
The source tunnel address and destination tunnel address uniquely identify a tunnel. The
destination tunnel address is the address of the interface receiving packets. The source address
of the local end is the destination address of the peer; the destination address of the local end is
the source address of the remote end.
You can configure different encapsulation modes for a tunnel interface based on its usage.
Pre-configuration Tasks
Before configuring a tunnel interface, complete the following tasks:
l Connecting interfaces and setting the physical parameters of each interface to make the
physical layer in Up state
l Setting the parameters of the link layer protocol and the IP address of the interface to enable
the link layer protocol.
Data Preparation
To configure a tunnel interface, you need the following data.
No.
Data
1 Tunnel interface number
2 Encapsulation protocol of a tunnel, source IP address of a tunnel, source interface,
and destination IP addresses of a tunnel
