MPLS L3VPN configuration examples

NOTE:
By default, Ethernet interfaces, VLAN interfaces, and aggregate interfaces are in DOWN state. To
configure such an interface, first use the undo shutdown command to bring the interface up.

Configuring MPLS L3VPNs using eBGP between PE and CE

Network requirements
CE 1 and CE 3 belong to VPN 1. CE 2 and CE 4 belong to VPN 2. Users of different VPNs cannot access
each other.
Specify the import and export route targets as 1 1 1:1 for VPN 1 and 222:2 for VPN 2.
Use eBGP to exchange VPN routing information between CE and PE.
In the MPLS backbone, use OSPF to ensure IP connectivity and use MP-iBGP to exchange VPN routing
information.
Use the command...
display mpls ldp vpn-instance vpn-instance-name
[ | { begin | exclude | include }
regular-expression ]
reset bgp vpn-instance vpn-instance-name
dampening [ network-address [ mask |
mask-length ]
reset bgp vpn-instance vpn-instance-name
ip-address flap-info
reset bgp vpn-instance vpn-instance-name flap-info
[ ip-address [ mask | mask-length ] | as-path-acl
as-path-acl-number | regexp as-path-regexp ]
