Example of configuring VRRP load sharing of multiple gateways on an AR router

3

An example of configuring VRRP load sharing of multiple gateways on an AR router is as follows:
In VRRP load sharing, multiple VRRP groups bear services, and each VRRP group contains a master device and multiple backup devices. The basic principle and packet negotiation procedure of VRRP load sharing are the same as those of VRRP active/standby backup. Unlike VRRP active/standby backup, multiple VRRP groups must be created to share load, the master devices of the groups can be different, and a VRRP device can be added into multiple groups and have different priorities in the groups.
For details about the configuration, see the URL: Example for Configuring a VRRP Group in Multi-gateway Load Balancing Mode.

Example of configuring a dot1Q termination sub-interface on an AR router to support VRRP
An example of configuring a dot1Q termination sub-interface on an AR router to support VRRP is as follows: The roadmap of configuring a dot1Q termination sub-interface to support VRRP and implement gateway redundancy is as follows: 1. Configure IP addresses and routing protocols for different device interfaces to enable network-layer routers to be reachable. 2. Configure a VRRP group on sub-interfaces of Router A and Router B, respectively. Configure a high priority and set preemption delay to 20s on Router A and configure Router A as a master device to bear and forward traffic. Configure a low priority and configure Router B as a backup device to implement redundancy. For details about the configuration, see the URL: Example for Configuring VRRP on a Dot1q Termination Sub-interface.

Does VRRP support per-packet load sharing on an AR router
Does VRRP support per-packet load sharing on an AR router? VRRP shares loads based on IP addresses. Therefore, it does not support per-packet load sharing. In VRRP load sharing, multiple VRRP groups bear services, and each VRRP group contains a master device and multiple backup devices. The basic principle and packet negotiation procedure of VRRP load sharing are the same as those of VRRP active/standby backup. Unlike VRRP active/standby backup, multiple VRRP groups must be created to share load, the master devices of the groups can be different, and a VRRP device can be added into multiple groups and have different priorities in the groups.

Example of configuring VRRP active/standby backup on an AR router
The roadmap of configuring VRRP active/standby backup on an AR router to implement gateway redundancy is as follows: 1. Configure IP addresses and routing protocols for different device interfaces to enable network-layer connection among different devices. 2. Configure a VRRP group on Router A and Router B, respectively. Configure a high priority and set preemption delay to 20s on Router A and configure Router A as a master device to bear and forward traffic. Configure a low priority and configure Router B as a backup device to implement gateway redundancy. Configure a VRRP group. # Create VRRP 1 on Router A, set its priority to 120, and set the preemption delay to 20s.

How do I configure VRRP load balancing on an S series switch
To configure VRRP load balancing on an S series switch (except the S1700), see section "Typical Reliability Configuration" at S1720&S2700&S3700&S5700&S6700&S7700&S9700 Typical Configuration Examples. The configuration method for the S9300 is the same as that for other switch models.

How do I configure a VRRP group in active/standby mode on an S series switch
