Description
Use the checkzero command to enable the zero field check on RIPv1 messages.
Use the undo checkzero command to disable the zero field check.
The zero field check is enabled by default.
After the zero field check is enabled, the router discards RIPv1 messages in which zero fields are
non-zero. If all messages are trusty, you can disable this feature to reduce the processing time of the
CPU.
Examples
# Disable the zero field check on RIPv1 messages for RIP process 100.
