Note:
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 S8500
series routing switch running routing protocols. To improve readability, this will not be
described in the other parts of the manual.

2.1 RIP Configuration Commands
2.1.1 checkzero
Syntax
checkzero
undo checkzero
View
RIP view
Parameter
None
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.
This command is ineffective to RIP-2 since RIP-2 packets have no zero fields.
