Configuring Soft GRE
Network requirements
As shown in Figure 35, CEs are connected to PEs through Layer 3 Ethernet interfaces.
Establish an SVC, so CE 1 and CE 2 can exchange Layer 2 packets across the backbone.
Configure Soft GRE to simplify public tunnel configuration.

Configuration procedure
1. Configure CE 1:
# Configure an IP address for Ethernet 1/1.
<Sysname> system-view
[Sysname] sysname CE1
[CE1] interface ethernet 1/1
[CE1-Ethernet1/1] ip address 100.1.1.1 24
2. Configure PE 1:
# Configure an LSR ID and enable MPLS globally.
<Sysname> system-view
[Sysname] sysname PE1
[PE1] interface loopback 0
[PE1-LoopBack0] ip address 192.2.2.2 32
[PE1-LoopBack0] quit
[PE1] mpls lsr-id 192.2.2.2
[PE1] mpls
[PE1-mpls] quit
# Enable L2VPN and MPLS L2VPN.
[PE1] l2vpn
