Module: TIMETRA-VRRP-V3-MIB
OID (symbolic): TIMETRA-VRRP-V3-MIB::vrrpStatisticsIpTtlErrors
OID (numeric): 1.3.6.1.2.1.68.2.5.1.4
Node type: OBJECT-TYPE

Description: The total number of VRRP packets received by the Virtual router with IPv4 TTL (for VRRP over IPv4) or IPv6 Hop Limit (for VRRP over IPv6) not equal to 255.
Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of vrrpStatisticsDiscontinuityTime.
What is vrrpStatisticsIpTtlErrors?
A running counter of VRRP packets received with an IPv4 TTL (or IPv6 hop limit) not equal to 255, which per RFC 3768 is required to guard against off-link spoofed VRRP packets — a nonzero count could indicate an attack or a misbehaving intermediate router.
