Configuration procedure
1. Configure MPLS L3VPN on the provider carrier backbone. Enable IS-IS as the IGP, enable LDP
between PE 1 and PE 2, and establish an MP-IBGP peer relationship between the PEs:
# Configure PE 1.
<PE1> system-view
[PE1] interface loopback 0
[PE1-LoopBack0] ip address 3.3.3.9 32
[PE1-LoopBack0] quit
[PE1] mpls lsr-id 3.3.3.9
[PE1] mpls ldp
[PE1-ldp] quit
[PE1] isis 1
[PE1-isis-1] network-entity 10.0000.0000.0000.0004.00
[PE1-isis-1] quit
[PE1] interface loopback 0
[PE1-LoopBack0] isis enable 1
[PE1-LoopBack0] quit
[PE1] interface vlan-interface 12
[PE1-Vlan-interface12] ip address 30.1.1.1 24
[PE1-Vlan-interface12] isis enable 1
[PE1-Vlan-interface12] mpls enable
[PE1-Vlan-interface12] mpls ldp enable
[PE1-Vlan-interface12] mpls ldp transport-address interface
[PE1-Vlan-interface12] quit
[PE1] bgp 100
[PE1-bgp] peer 4.4.4.9 as-number 100
[PE1-bgp] peer 4.4.4.9 connect-interface loopback 0
[PE1-bgp] address-family vpnv4
[PE1-bgp-vpnv4] peer 4.4.4.9 enable
[PE1-bgp-vpnv4] quit
[PE1-bgp] quit
# Configure PE 2 in the same way that PE 1 is configured. (Details not shown.)
# On PE 1 or PE 2, execute the following commands:
{
Execute the display mpls ldp peer command to verify that an LDP session in Operational state
has been established between PE 1 and PE 2. (Details not shown.)
{
Execute the display bgp peer vpnv4 command to verify that a BGP peer relationship in
Established state has been established between PE 1 and PE 2. (Details not shown.)
{
Execute the display isis peer command to verify that the IS-IS neighbor relationship has been
established between PE 1 and PE 2. (Details not shown.)
2. Configure the customer carrier network. Enable IS-IS as the IGP, and enable LDP between PE 3 and
CE 1, and between PE 4 and CE 2:
# Configure PE 3.
<PE3> system-view
[PE3] interface loopback 0
[PE3-LoopBack0] ip address 1.1.1.9 32
[PE3-LoopBack0] quit
