2. Configure basic MPLS on the PEs:

# Configure PE 1.

<PE1> system-view

[PE1] mpls lsr-id 1.1.1.9

# Configure PE 2.

<PE2> system-view

[PE2] mpls lsr-id 2.2.2.9

3. Configure VPN instances on PEs to allow CE access, and apply tunnel policies to the VPN

instances, using a GRE tunnel for VPN packet forwarding:

# Configure PE 1.

[PE1] tunnel-policy gre1

[PE1-tunnel-policy-gre1] select-seq gre load-balance-number 1

[PE1-tunnel-policy-gre1] quit

[PE1] ip vpn-instance vpn1

[PE1-vpn-instance-vpn1] route-distinguisher 100:1

[PE1-vpn-instance-vpn1] vpn-target 100:1 both

[PE1-vpn-instance-vpn1] tnl-policy gre1

[PE1-vpn-instance-vpn1] quit

[PE1] interface ethernet 1/1

[PE1-Ethernet1/1] ip binding vpn-instance vpn1

[PE1-Ethernet1/1] ip address 10.1.1.2 24

[PE1-Ethernet1/1] quit

# Configure PE 2.

[PE2] tunnel-policy gre1

[PE2-tunnel-policy-gre1] select-seq gre load-balance-number 1

[PE2-tunnel-policy-gre1] quit

[PE2] ip vpn-instance vpn1

[PE2-vpn-instance-vpn1] route-distinguisher 100:2

[PE2-vpn-instance-vpn1] vpn-target 100:1 both

[PE2-vpn-instance-vpn1] tnl-policy gre1

[PE2-vpn-instance-vpn1] quit

[PE2] interface ethernet 1/1

[PE2-Ethernet1/1] ip binding vpn-instance vpn1

[PE2-Ethernet1/1] ip address 10.2.1.2 24

[PE2-Ethernet1/1] quit

# Configure CE 1.

<CE1> system-view

[CE1] interface ethernet 1/1

[CE1-Ethernet1/1] ip address 10.1.1.1 24

[CE1-Ethernet1/1] quit

# Configure CE 2.

<CE2> system-view

[CE2] interface ethernet 1/1

[CE2-Ethernet1/1] ip address 10.2.1.1 24

[CE2-Ethernet1/1] quit
