Usage Guidelines
The other-config-flag command enables verification of the advertised "other" configuration parameter (or
"O" flag). This flag could be set by an attacker to force hosts to retrieve other configuration information
through a Dynamic Host Configuration Protocol for IPv6 (DHCPv6) server that may not be trustworthy.
Examples
The following example shows how the command defines a router advertisement (RA) guard policy name as
raguard1, places the router in RA guard policy configuration mode, and enables O flag verification:
switch(config)# ipv6 nd raguard policy raguard1
switch(config-ra-guard)# other-config-flag on
