rip poison-reverse

Function

The rip poison-reverse command configures poison reverse for RIP Update packets.

The undo rip poison-reverse command cancels the configuration.

By default, poison reverse is disabled.

Format

undo rip poison-reverse

Parameters

None

Views

Ethernet interface view, Ethernet sub-interface view, Eth-Trunk interface view, Eth-Trunk sub-interface view, Tunnel interface view, Dialer interface view, VLANIF interface view, Virtual-Template interface view

Default Level

2: Configuration level

Usage Guidelines

After poison reverse is configured and RIP learns a route from a specific interface, RIP sets the cost of the route to 16 (indicating unreachable) and then sends the route to the neighbor through the same interface.

When both split horizon and poison reverse are configured, only poison reverse takes effect.

Example

# Configure poison reverse for RIP Update packets.

<sysname> system-view
[sysname] interface GigabitEthernet 0/0/1
[sysname-GigabitEthernet0/0/1] rip poison-reverse
