Usage guidelines
Some fields in RIPng packet headers must be zero. These fields are called zero fields. You can enable zero field check on incoming RIPng packets. If a zero field of a packet contains a non-zero value, RIPng discards the packet.
Examples
# Disable zero field check on RIPng packets for RIPng 100.
<Sysname> system-view [Sysname] ripng 100 [Sysname-ripng-100] undo checkzero
