Usage guidelines
• The split horizon function prevents routing loops. If you want to disable the function, make sure that
the operation is dispensable.
• On NBMA networks, such as FR and X.25 where multiple VCs are configured on the primary and
secondary interfaces, disable split horizon to ensure correct route advertisement. For more
information about FR and X.25, see Layer 2—WAN Configuration Guide.
• If both split horizon and poison reverse are enabled, only the poison reverse function takes effect.
Examples
# Enable the split horizon function on Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet 1/1
