6.3.2 Configuring MGRE

To configure MGRE, create a tunnel interface, and configure the tunnel encapsulation mode, IP
address, and source address for the tunnel interface.
Context
After creating a tunnel interface, set the tunnel encapsulation mode to Multipoint GRE (MGRE)
and configure a source address for the tunnel interface. To enable the tunnel interface to support
dynamic routing protocols, configure an IP address for the tunnel interface. Perform the
following operations on the routers of branches and the central office.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface tunnel interface-number
A tunnel interface is created and the tunnel interface view is displayed.
Step 3 Run:
tunnel-protocol gre p2mp
The tunnel encapsulation mode is set to MGRE.
Step 4 Run:
ip address ip-address { mask | mask-length }
The IP address of the tunnel interface is configured.
Step 5 Run:
source { source-ip-address | interface-type interface-number
The source address or source interface is configured for the tunnel interface.

6.3.3 Configuring Tunnel Routes

To implement DSVPN, configure routes between branches.
Context
The routes passing through a tunnel must be available on branches and the central office so that
packets encapsulated with the MGRE header can be forwarded correctly. These routes can be
static routes or dynamic routes. Perform the following operations on the routers of branches and
the central office.
Issue 01 (2012-04-20)
NOTE
You must configure the tunnel encapsulation mode before setting the source IP address or other parameters
for a tunnel interface. Changing the encapsulation mode of a tunnel interface deletes other parameters of
the tunnel interface.
