Network Topology

DRNI combined with VRRP networking


Problem Description

The DRNI configuration is normal, the VRRP status is normal, and the interfaces are all Up, but the Virtual IP is unreachable.

Process Analysis

By querying the configuration guide, we found that there is a missing command: undo mac-address static source-check enable. After this command is used to disable the matching check function between the incoming interface of the packet and the static MAC address entry, the virtual IP can be reached.


Disabling static source check

About this task

By default, the static source check feature is enabled on an interface. The check identifies whether a received frame meets the following conditions:

·     The source MAC address of the frame matches a static MAC address entry.

·     The incoming interface of the frame is different from the outgoing interface in the entry.

If the frame meets both conditions, the device drops the frame.

When this feature is disabled, the device does not perform the check for a received frame. It can forward the frame whether or not the frame meets the conditions.

Procedure

1.     Enter system view.

system-view

2.     Disable the static source check feature.

undo mac-address static source-check enable

By default, the static source check feature is enabled.


This is because both DR devices will have VRRP master, VRRP standby and virtual IP mac addresses on the bottom layer. When this feature is enabled, when the message sent by the standby device with the source mac to the master device, the master device will check the source mac of the message and find that it has this mac address on the bottom layer, it will think it is sent by itself and thus discard the message.

Solution

Configure undo mac-address static source-check enable in the system view to disable the static source check feature.
