Example for Configuring L3VPN and VRRP

L3VPN and VRRP Overview

L3VPN is suitable for communication between the headquarters and branches in different locations. As communication data needs to traverse the backbone network of the ISP, BGP is used to advertise VPN routes and MPLS is used to forward VPN packets on the backbone network. As different departments of an enterprise need to be isolated, BGP/MPLS IP VPN can implement route isolation, address space isolation, and access isolation between different VPNs.

Generally, all hosts on the same network segment have the same default route with the gateway address as the next hop address. The hosts use the default route to send packets to the gateway and the gateway forwards the packets to other network segments. When the gateway fails, the hosts with the same default route cannot communicate with external networks. Configuring multiple egress gateways is a common method to improve system reliability. However, route selection between the gateways becomes an issue.

VRRP solves the problem. VRRP virtualizes multiple routing devices into a virtual router without changing the networking, and uses the virtual router IP address as the default gateway address to implement gateway backup. When the master in the virtual router fails, VRRP uses a backup to transmit service traffic.

It is recommended that you set the preemption delay of the backup in a VRRP group to 0, configure the master in preemption mode, and set the preemption delay to be longer than 15s. These settings allow a period of time for status synchronization between the uplink and downlink on an unstable network. If the preceding settings are not used, two masters may coexist and user devices may learn incorrect address of the master. As a result, traffic is interrupted.

  • Preemption mode: A backup preempts to be the master when its priority is higher than the master.

  • Non-preemption mode: As long as the master is working properly, the backup with a higher priority cannot become the master.

Configuration Notes

  • Ensure that each device of the same VRRP group is configured with the same VRID.

  • In V200R003 and earlier versions, VRRP can be configured only on the VLANIF interface.

    In V200R005 and later versions, VRRP can be configured on the VLANIF interface and Layer 3 Ethernet interface.

    For a modular switch in V200R006 and later versions, VRRP can be configured on the VLANIF interface, Layer 3 Ethernet interface, Dot1q termination sub-interface, and QinQ termination sub-interface.

    For a fixed switch in V200R009 and later versions, VRRP can be configured on the VLANIF interface, Layer 3 Ethernet interface, and sub-interface.

  • The SA series cards do not support the BGP/MPLS IP VPN function. The X1E series cards of V200R006C00 and later versions support the BGP/MPLS IP VPN function.
  • Applicable products and versions lists applicable products and versions.

For details about software mappings, visit Hardware Query Tool and search for the desired product model.

Networking Requirements

In Figure 1, CE1 and CE2 belong to vpna, and CE1 is dual-homed to PE1 and PE2 through the switch. The requirements are as follows:

  • Normally, CE1 uses PE1 as the default gateway to communicate with CE2. When PE1 becomes faulty, PE2 takes over PE1, implementing gateway redundancy.

  • After PE1 recovers, it preempts to be the master to transmit data after a preemption delay of 20s.

In this scenario, to avoid loops, ensure that all connected interfaces have STP disabled and connected interfaces are removed from VLAN 1. If STP is enabled and VLANIF interfaces of switches are used to construct a Layer 3 ring network, an interface on the network will be blocked. As a result, Layer 3 services on the network cannot run normally.

Configuration Roadmap

VRRP is configured to implement gateway redundancy on the L3VPN. The configuration roadmap is as follows:

  1. Configure OSPF between PEs to implement IP connectivity on the backbone network.
  2. Configure basic MPLS functions and MPLS LDP on PEs so that MPLS LSPs can be established to transmit VPN data.
  3. Configure VPN instances on PEs to implement connectivity between VPNs. Bind VPN instances to PE interfaces connected to CEs so that VPN users can be connected.
  4. Configure MP-IBGP between PE1 and PE3, and between PE2 and PE3 to exchange VPN routing information.
  5. Configure EBGP between CEs and PEs to exchange VPN routing information.
  6. Configure a loop prevention protocol on PE1, PE2, and switch to prevent loops. Here, MSTP is used.
  7. Configure a VRRP group on PE1 and PE2. Set a higher priority for PE1 so that PE1 functions as the master to forward traffic, and set the preemption delay to 20s on PE1. Set a lower priority for PE2 so that PE2 functions as the backup.

Procedure

  1. Configure an IGP protocol on the MPLS backbone network so that the PEs can communicate with each other.
