cospfShamLinksRtrDeadInterval
Module: CISCO-OSPF-MIB
OID (symbolic): CISCO-OSPF-MIB::cospfShamLinksRtrDeadInterval
OID (numeric): 1.3.6.1.4.1.9.10.99.11.1.8
Node type: OBJECT-TYPE
Type: PositiveInteger
Access: read-only
Description: The number of seconds that a router's Hello packets have not been seen before it's neighbors declare the router down. This should be some multiple of the Hello interval.
What is cospfShamLinksRtrDeadInterval?
This object reports the dead interval for a sham link via the ShamLinks table, functionally identical to cospfShamLinkRtrDeadInterval, expected to be configured as a multiple of the corresponding Hello interval. The same tuning logic applies: too short a value risks unnecessary adjacency flaps if the underlying VPN transport has occasional brief hiccups, and this alternate table should be checked for consistency against its ShamLink counterpart if both exist for the same link.
