VRRP Configuration
The Virtual Router Redundancy Protocol (VRRP) is a fault-tolerant protocol that allows logical devices to operate separately from physical devices. VRRP improves device reliability and simplifies host configurations.
- Overview of VRRP
The Virtual Router Redundancy Protocol (VRRP) is a fault-tolerant protocol running on routers. VRRP implements egress gateway backup and ensures communication continuity and reliability. - VRRP Licensing Requirements and Configuration Precautions
- Configuring Basic VRRP Functions
VRRP works in either master/backup or load balancing mode, implementing device backup and efficient and stable data forwarding. - Configuring an mVRRP Group
mVRRP is used when multiple VRRP groups coexist. mVRRP helps decrease the number of VRRP Advertisement packets to be sent and minimize network bandwidth consumption. - Configuring VRRP Association
VRRP association helps a VRRP group rapidly perform a master/backup VRRP switchover if a network link fails. VRRP association ensures user data forwarding. - Enabling Rapid VRRP Switchback
This section describes how to enable rapid Virtual Router Redundancy Protocol (VRRP) switchback. - Enabling Enhanced Sending and Replication of Gratuitous ARP Packets for a VRRP Group
After enhanced sending and replication of gratuitous ARP packets is enabled for a VRRP group, when a backup device in the VRRP group assumes the master role, it sends a gratuitous ARP packet for each virtual IP address six consecutive times. At the same time, the device replicates each gratuitous ARP packet to be sent to each Eth-Trunk member interface if the VRRP group is configured on an Eth-Trunk interface or Eth-Trunk sub-interface. This ensures that downstream devices can receive the gratuitous ARP packets and update destination MAC addresses and outbound interfaces in time. - Maintaining VRRP
By maintaining VRRP, you clear the VRRP statistics and monitor the VRRP operating status. - Configuration Examples for VRRP
This section provides VRRP configuration examples.
