NOTE:
•
To configure a multi-hop PW, specify the p2p keyword when you create a VPLS instance to enable the
PW to PW (P2P) capability, and specify the two peer PEs by using the peer command in the VPLS
instance view to associate two PWs.
• A P2P enabled VPLS instance cannot be bound with a Layer 3 interface or a service instance.
• Up to two peer PEs can be specified for a P2P enabled VPLS instance, and one of them must be specified
as a UPE.
Configuring BGP VPLS
Configuration prerequisites
• Configure IGP on the MPLS backbone devices (PEs and P devices) to guarantee the IP connectivity
of the MPLS backbone. For configuration details, see Layer 3—IP Routing Configuration Guide.
• Configure basic MPLS on the MPLS backbone devices (PEs and P devices) to establish LSP tunnels
on the backbone network. For configuration information, see the chapter “Configuring basic
MPLS.”
Configuring the BGP extension
Before configuring BGP VPLS, you need to configure BGP parameters on the PEs. For configuration
details, see Layer 3—IP Routing Configuration Guide.
To configure BGP extension:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Enter VPLS address family
view.
vpls-family N/A
4. Activate a peer. peer peer-address enable No peer is activated by default.
NOTE:
For configurations in VPLS address family view, see the chapter “Configuring MPLS L3VPN.”
Enabling L2VPN and MPLS L2VPN
Enable L2VPN and MPLS L2VPN before you configure VPLS related configurations.
To enable L2VPN and MPLS L2VPN:
Step Command
1. Enter system view. system-view
2. Configure the LSR ID. mpls lsr-id
3. Enable MPLS capability and enter MPLS view. mpls
