By default:
• The garbage-collect timer is 120

• The timeout timer is 180 seconds.
• The update timer is 30 seconds.
Configuring split horizon and poison reverse
The split horizon and poison reverse functions can prevent routing loops.
If both split horizon and poison reverse are configured, only the poison reverse function takes effect.
Enabling split horizon
Split horizon disables RIP from sending routes through the interface where the routes were learned to
prevent routing loops between adjacent routers.
To enable split horizon:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.

interface-number
N/A
3. Enable split horizon.
rip split-horizon By default, split horizon is enabled.
Enabling poison reverse
Poison reverse allows RIP to send routes through the interface where the routes were learned, but the
metric of these routes is always set to 16 (unreachable) to avoid routing loops between neighbors.
To enable poison reverse:
