Example for Configuring an Eth-Trunk and Association Between VRRP and the Interface Status

Example for Configuring an Eth-Trunk and Association Between VRRP and the Interface Status

Association Between VRRP and the Interface Status

Additional technologies are required to enhance the VRRP active/standby function. For example, when the link from the master to a network is disconnected, VRRP cannot detect the fault and an active/standby switchover cannot be performed. As a result, hosts cannot remotely access the network through the master. To address this issue, you can configure association between VRRP and the interface status.

When the master detects that the uplink interface fails, the master reduces its priority to be lower than the priority of the backup and immediately sends VRRP packets. After the backup receives the VRRP packets, it detects that the priority in the VRRP packets is lower than its priority and switches to the master. This ensures correct traffic forwarding.

Configuration Notes

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

    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.

  • Ensure that each device of the same VRRP group is configured with the same VRID.
  • VRRP groups must use different virtual IP addresses. The virtual IP address of a VRRP group must be on the same network segment as the IP address of the interface where the VRRP group is configured.

  • A VRRP group can be associated with a maximum of eight interfaces. Association between a VRRP group and the interface status cannot be configured on the device as the IP address owner.

  • This example applies to all versions of the S12700.

Networking Requirements

As shown in Figure 13-5, the user hosts are dual-homed to SwitchA and SwitchB through the switch. The requirements are as follows:
  • The hosts use SwitchA as the default gateway to connect to the Internet. When SwitchA or the downlink/uplink fails, SwitchB functions as the gateway to implement gateway backup.

  • The bandwidth of the link between SwitchA and SwitchB is increased to implement link backup and improve link reliability.

  • After SwitchA recovers, it becomes the gateway within 20s.

Configuration Roadmap

A VRRP group in active/standby mode is used to implement gateway backup. The configuration roadmap is as follows:

  1. Assign an IP address to each interface and configure a routing protocol to ensure network connectivity.

  2. Configure VLAN aggregation on SwitchA and SwitchB to implement Layer 2 isolation and Layer 3 connectivity of VLANs 101 to 180 and save IP addresses.

  3. Create an Eth-Trunk on SwitchA and SwitchB and add member interfaces to the Eth-Trunk to increase the link bandwidth and implement link backup.

  4. Configure a VRRP group between SwitchA and SwitchB. Set a higher priority for SwitchA so that SwitchA functions as the master to forward traffic, and set the preemption delay to 20s on SwitchA. Set a lower priority for SwitchB so that SwitchB functions as the backup.

  5. Associate VRRP with GE1/0/1 and GE1/0/2 on SwitchA so that the VRRP group can detect the fault of the master and perform an active/standby switchover immediately.

NOTE:

SwitchA and SwitchB are core switches, and the switch is an aggregation switch.

Procedure

    # Assign an IP address to each interface on core devices. SwitchA is used as an example. The configuration of SwitchB is similar to the configuration of SwitchA, and is not mentioned here. For details, see the configuration files.
