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
