When an Ethernet switch runs a routing protocol, it can perform the router functions.
Router that is referred to in the following and its icon represent a generalized router or
an Ethernet switch running routing protocols.

2.1 RIP Configuration Commands
2.1.1 checkzero
Syntax
checkzero
undo checkzero
View
RIP view
Parameter
None
Description
Using
checkzero
command, you can check the zero field of RIP-1 packet. Using
undo
checkzero
command, you can disable the checking of the zero fields.
By default, RIP-1 performs the zero field checking.
According to the protocol (RFC1058) specifications, some fields in RIP-1 packets must
be zero, called zero fields. With the
checkzero
command, the zero check operation of
RIP-1 can be enabled or disabled. During the zero 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.
[Quidway-rip] undo checkzero
