This object indicates the interval for updating LSAs, excluding OSPF router
LSAs and network LSAs. hwOspfv2LsaOrigIntvlOtherType and hwOspfv2LsaOrigIntvl
cannot be specified together. Here -1 indicated that hwOspfv2LsaOrigIntvl is
enabled instead. Note that -1 is not a configurable value. Instead, by set
this node to default value, it will get back to default configuration.
