# Configure the PE-agg.
[PEagg] l2vpn
[PEagg-l2vpn] mpls l2vpn
[PEagg-l2vpn] quit
e. Configure the PE-CE interfaces of PE 1 and PE-agg, and create an MPLS L2VPN connection that
supports interworking on the interfaces:
# On Serial 2/0 of PE 1, create an MPLS L2VPN connection that supports interworking and
configure PPP to support IPCP negotiation without IP address.
[PE1] interface serial 2/0
[PE1-Serial2/0] link-protocol ppp
[PE1-Serial2/0] ppp ipcp ignore local-ip
[PE1-Serial2/0] mpls l2vc 3.3.3.9 101 ip-interworking
[PE1-Serial2/0] quit
# On the terminating VE interface of the PE-agg, create an MPLS L2VPN connection that
supports interworking and configure the default next hop as 100.1.1.2.
[PEagg] interface ve-l2vpn-terminate 1
[PEagg-VE-L2VPN-Terminate1] default-nexthop ip 100.1.1.2
[PEagg-VE-L2VPN-Terminate1] mpls l2vc 1.1.1.9 101 ip-interworking
[PEagg-VE-L2VPN-Terminate1] quit
f. Configure the PE-CE interface of CE 1—serial 2/0—to use PPP encapsulation.
<CE1> system-view
[CE1] interface serial 2/0
[CE1-Serial2/0] link-protocol ppp
[CE1-Serial2/0] ip address 100.1.1.1 24
4. Configure MPLS L3VPN:
a. Configure IS-IS on PE 2 and PE-agg, and advertise interface addresses:
# Configure the PE-agg.
[PEagg] isis 1
[PEagg-isis-1] network-entity 10.0000.0000.0001.00
[PEagg-isis-1] quit
[PEagg] interface pos 5/1
[PEagg-Pos5/1] isis enable 1
[PEagg-Pos5/1] quit
[PEagg] interface loopback 0
[PEagg-LoopBack0] isis enable 1
[PEagg-LoopBack0] quit
# Configure PE 2.
[PE2] isis 1
[PE2-isis-1] network-entity 10.0000.0000.0002.00
[PE2-isis-1] quit
[PE2] interface pos 5/0
[PE2-Pos5/0] isis enable 1
[PE2-Pos5/0] quit
[PE2] interface loopback 0
[PE2-LoopBack0] isis enable 1
[PE2-LoopBack0] quit
b. Configure basic MPLS and enable MPLS LDP on PE-agg and PE 2:
