DESCRIPTION
   "The MIB module to describe the OSPF Version 2
   Protocol"
::= { mib-2 14 }

-- The Area ID, in OSPF, has the same format as an IP Address, -- but has the function of defining a summarization point for -- Link State Advertisements

AreaID ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "An OSPF Area Identifier." SYNTAX IpAddress

-- The Router ID, in OSPF, has the same format as an IP Address, -- but identifies the router independent of its IP Address.

RouterID ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A OSPF Router Identifier." SYNTAX IpAddress

-- The OSPF Metric is defined as an unsigned value in the range

Metric ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The OSPF Internal Metric." SYNTAX Integer32 (0..'FFFF'h)

BigMetric ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The OSPF External Metric." SYNTAX Integer32 (0..'FFFFFF'h)

-- Status Values

Status ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The status of an interface: 'enabled' indicates that it is willing to communicate with other OSPF Routers, while 'disabled' indicates that it is not." SYNTAX INTEGER { enabled (1), disabled (2) }

-- Time Durations measured in seconds

PositiveInteger ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A positive integer. Values in excess are precluded as unnecessary and prone to interoperability issues." SYNTAX Integer32 (0..'7FFFFFFF'h)

HelloRange ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The range of intervals on which hello messages are exchanged." SYNTAX Integer32 (1..'FFFF'h) UpToMaxAge ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The values that one might find or configure for variables bounded by the maximum age of an LSA." SYNTAX Integer32 (0..3600)

-- The range of ifIndex

InterfaceIndex ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The range of ifIndex." SYNTAX Integer32

-- Potential Priorities for the Designated Router Election

DesignatedRouterPriority ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The values defined for the priority of a system for becoming the designated router." SYNTAX Integer32 (0..'FF'h)

TOSType ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "Type of Service is defined as a mapping to the IP Type of Service Flags as defined in the IP Forwarding Table MIB
