Use the checkzero command to enable the must be zero field check for RIP-1 packets.  

Use the undo checkzero command to disable the must be zero field check for RIP-1 packets. 

By default, RIP-1 performs the must be zero field check. 

According to the protocol (RFC 1058) specifications, some fields in RIP-1 packets must be zero and 
these fields are called zero fields. You can use the checkzero command to enable/disable the must be 

 field check for RIP-1 packets. When the must be zero field check is enabled, if the must be zero 

field in an incoming RIP-1 packet is non-zero, the packet will be rejected. 

# Disable the must be zero field check for RIP-1 packets.
