When a switch runs a routing protocol, it can perform the router functions. A
router that is referred to in the following or its icon represents a generalized router
or an Switch 8800 Family series routing switch running routing protocols. To
improve readability, this will not be described in the other parts of the manual.

Description
Use the checkzero command to check the zero field of RIP-1 packet.
Use the undo checkzero command to disable the checking of the zero fields.
By default, RIP-1 performs zero field check.
According to the protocol (RFC1058) specifications, some fields in RIP-1 packets
must be zero, called zero fields. You can use the checkzero command to enable
the zero field check operation on RIP-1 packet. During the zero field check
operation, if the RIP-1 packet in which the zero fields are not zeros is received, it
will be rejected.
must be zero, called zero fields. You can use the checkzero command to enable
the zero field check operation on RIP-1 packet. During the zero field check
operation, if the RIP-1 packet in which the zero fields are not zeros is received, it
will be rejected.
This command is ineffective to RIP-2 since RIP-2 packets have no zero fields.
Example
# Configure not to perform zero check for RIP-1 packet.
