Module: DOCS-RPHY-MIB

OID (symbolic): DOCS-RPHY-MIB::docsRphyRpdIpDefaultRouterLifetime

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: The remaining length of time, in seconds, that this router will continue to be useful as a default router. A value of zero indicates that it is no longer useful as a default router. It is left to the implementer of the MIB as to whether a router with a lifetime of zero is removed from the list.

For IPv6, this value should be extracted from the router advertisement messages.
