NOTE:
An IRF link failure can cause an IRF virtual device to split into two IRF virtual devices operating with the
•
same Layer 3 configurations, such as the same IP address.
To avoid IP address collision and network problems, configure the multi-active detection (MAD)
•
mechanism to detect the presence of multiple identical IRF virtual devices and handle collisions. For
more information about MAD detection, see the
Configuration Guide.
