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:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter interface view.
interface
interface-type
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. The
metric of these routes is always set to 16 (unreachable) to avoid routing loops between neighbors.
To enable poison reverse:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter interface view.
interface
interface-type
interface-number
N/A
3. Enable poison reverse.
rip poison-reverse
By default, poison reverse is
disabled.
Configuring the maximum number of ECMP routes
Perform this task to implement load sharing over ECMP routes.
To configure the maximum number of ECMP routes:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter RIP view.
rip
[ process-id ] [
vpn-instance
vpn-instance-name ]
N/A
3. Configure the maximum
number of ECMP routes.
maximum load-balancing
number
By default, the maximum number
of RIP ECMP routes equals the
maximum number of ECMP
routes supported by the system.
Use the
max-ecmp-num
command to configure the
maximum number of ECMP
routes supported by the system.
For more information about the
max-ecmp-num
command, see
Layer 3—IP Routing Command
