Enabling Split Horizon And Poison Reverse; Setting The Maximum Number Of Rip Ecmp Routes - HP HPE FlexNetwork 7500 series Configuration Manual

Step
3. Set RIP timers.

Enabling 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:
Step
1. Enter system view.
2. Enter interface view.
3. Enable split horizon.
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
1. Enter system view.
2. Enter interface view.
3. Enable poison reverse.

Setting the maximum number of RIP ECMP routes

Perform this task to implement load sharing over ECMP routes.
To set the maximum number of RIP ECMP routes:
Step
1. Enter system view.
