Configuring A Gre Tunnel Between Ce And Pe; Establishing The Configuration Task - Huawei Quidway S9300 Configuration Manual

Quidway S9300 Terabit Routing Switch
Configuration Guide - VPN
Run the display ip routing-table command, and you can see that the routing table contains the
route passing through the tunnel interface. The following is an example:
<Quidway> display ip routing-table
Route Flags: R - relied, D - download to fib
------------------------------------------------------------------------------
Routing Tables: Public
Destination/Mask
Run the ping -a source-ip-address dest-ip-address command, and you can see that the local
tunnel interface can ping the destination tunnel interface.

2.4 Configuring a GRE Tunnel Between CE and PE

This section describes how to configure a CE to access the public network by using a GRE
tunnel.

2.4.1 Establishing the Configuration Task

2.4.2 Configuring the GRE Tunnel Interface on CE
2.4.3 Configuring the GRE Tunnel Interface on PE
2.4.4 Binding the Tunnel with VPN to Which CE belongs on PE
2.4.5 Checking the Configuration
2.4.1 Establishing the Configuration Task
Applicable Environment
To allow users of the CE that is not directly connected with a PE to access the Multi-Protocol
Label Switching (MPLS) VPN, configure a GRE tunnel and create routes between them and
configure MPLS VPN on the PE.
