Usage guidelines
• The split horizon function is necessary for preventing routing loops. To disable it in special cases,
make sure it is necessary.
• In Frame Relay, X.25 and other non-broadcast multi-access (NBMA) networks, split horizon should
be disabled if multiple VCs are configured on the primary and secondary interfaces to ensure route
advertisement. For detailed information, see Layer 2—WAN Configuration Guide.
Only the poison reverse function takes effect if both the split horizon and poison reverse functions are
enabled.
Examples
# Enable the split horizon function on GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
