R3303-HP HSR6800 Routers Layer 3 - IP Routing Configuration Guide

31
On NBMA networks such as FR and X.25 where multiple VCs are configured on the primary and
secondary interfaces, disable split horizon to ensure correct route advertisement. For more information,
see Layer 2—WAN Configuration Guide.
Disabling split horizon on point-to-point links does not take effect.
To enable split horizon:
Ste
p
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
Optional.
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:
Ste
p
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:
Ste
p
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
Optional.
By default, the maximum number of
ECMP routes is 8.
Enabling zero field check on incoming RIPv1 messages
Some fields in the RIPv1 message must be set to zero. These fields are called "zero fields." You can
enable zero field check on incoming RIPv1 messages. If a zero field of a message contains a non-zero
