cospfShamLinkHelloInterval
Module: CISCO-OSPF-MIB
OID (symbolic): CISCO-OSPF-MIB::cospfShamLinkHelloInterval
OID (numeric): 1.3.6.1.4.1.9.10.99.6.1.5
Node type: OBJECT-TYPE
Type: HelloRange
Access: read-only
Description: The length of time, in seconds, between the Hello packets that the router sends on the sham link.
What is cospfShamLinkHelloInterval?
This object reports how frequently, in seconds, OSPF Hello packets are sent across a sham link to maintain the adjacency between the two routers pretending to be directly connected over an MPLS VPN backbone. It matters because both ends of a sham link must agree on this interval, along with the dead interval, or the adjacency will never properly form, making this one of the first values an admin checks when a configured sham link refuses to come up. A mismatch here between the two sham-link endpoints, say 10 seconds configured on one side and 5 on the other, would prevent the OSPF adjacency from establishing at all.
