Configuring PBB-EVPN on UPEs on One Side

Configuring provider backbone bridge Ethernet VPN (PBB-EVPN) on user-end provider edges (UPEs) is the prerequisite for migrating a hierarchical virtual private LAN service (HVPLS) network to a PBB-EVPN.

Context

Configuring PBB-EVPN on a UPE includes configuring a B-EVPN instance and an I-EVPN instance, binding an interface to the I-EVPN instance, configuring an Ethernet segment identifier (ESI), configuring a PBB-EVPN source address, and configuring B-MAC addresses. B-MAC addresses can be configured in one or more of the following views:

B-EVPN instance view
I-EVPN instance view
View of a PE interface connecting to a CE

B-MAC addresses configured in these views must be different. PBB preferentially uses the B-MAC addresses configured in the interface view for packet encapsulation. If no B-MAC addresses are configured in the interface view, PBB uses B-MAC addresses configured in the I-EVPN instance view instead. If no B-MAC addresses are configured in the I-EVPN instance view either, PBB uses B-MAC addresses configured in the B-EVPN instance view.

Procedure

Configure a B-EVPN instance.
1. Run system-view
  The system view is displayed.
2. Run evpn vpn-instance vpn-instance-name b-evpn
  A B-EVPN instance is created, and its view is displayed.
3. (Optional) Run description description-information
  A description is configured for the B-EVPN instance.
  
  Similar to a hostname or an interface description, a B-EVPN instance description helps you memorize the B-EVPN instance.
4. Run route-distinguisher route-distinguisher
  A route distinguisher (RD) is configured for the B-EVPN instance.
  
  A B-EVPN instance takes effect only after the RD is configured. The RDs of different EVPN instances on a UPE must be different.
  
  After being configured, an RD cannot be modified, but can be deleted. After you delete the RD of a B-EVPN instance, the VPN targets of the B-EVPN instance will also be deleted.
5. Run vpn-target vpn-target &<1-8> [ both | export-extcommunity | import-extcommunity ]
  VPN targets are configured for the B-EVPN instance.
  
  A VPN target is a BGP extended community attribute used to control the receiving and advertisement of EVPN routes. A maximum of eight VPN targets can be configured using a vpn-target command. To configure more VPN targets for an EVPN instance address family, run the vpn-target command several times.
6. (Optional) Run pbb backbone-source-mac mac-address
  A B-MAC address is configured in the B-EVPN instance view.
7. (Optional) Run tnl-policy policy-name
  The B-EVPN instance is associated with a tunnel policy.
  
  This configuration enables UPEs to use TE tunnels to transmit data packets.
8. Run commit
  The configuration is committed.
Configure an I-EVPN instance.
1. Run system-view
  The system view is displayed.
2. Run evpn vpn-instance vpn-instance-name i-evpn
  An I-EVPN instance is created, and its view is displayed.
3. (Optional) Run description description-information
  A description is configured for the I-EVPN instance.
  
  Similar to a hostname or an interface description, an I-EVPN instance description helps you memorize the I-EVPN instance.
4. Run pbb i-tag i-tag
  An I-SID is configured for the I-EVPN instance.
5. Run pbb binding b-evpn vpn-instance-name
  The I-EVPN instance is bound to the B-EVPN instance.
6. (Optional) Run pbb backbone-source-mac mac-address
  A B-MAC address is configured in the I-EVPN instance view.
7. Run commit
  The configuration is committed.
Bind an interface to an I-EVPN instance.
1. Run system-view
  The system view is displayed.
2. Run interface interface-type interface-number
  The view of the UPE interface connecting to a CE is displayed.
3. Run evpn binding vpn-instance vpn-instance-name
  The interface is bound to the I-EVPN instance.
4. (Optional) Run pbb backbone-source-mac mac-address
  A B-MAC address is configured in the interface view.
5. Run commit
  The configuration is committed.
Configure a PBB-EVPN source address.
1. Run system-view
  The system view is displayed.
2. Run evpn source-address ip-address
  A PBB-EVPN source address is configured.
3. Run commit
  The configuration is committed.
Configure an ESI.
