Module: CISCOSB-IPV6FHS-MIB
OID (symbolic): CISCOSB-IPV6FHS-MIB::rlRaGuardPolicyHopLimitMin
OID (numeric): 1.3.6.1.4.1.9.6.1.101.215.3.1.1.3
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write

What is rlRaGuardPolicyHopLimitMin?
This read-write Integer32 (-1, 0, or 1..255) in the RA Guard policy table sets the minimum acceptable Hop Limit field value in Router Advertisements, where -1 means unspecified and 0 disables the check. An admin cares because a suspiciously low Hop Limit can indicate a spoofed or multi-hop-relayed rogue RA rather than a genuine local router. For example, setting this to 64 on policy "raguard-host" causes RA Guard to drop any RA whose Hop Limit is below 64.
