CISCO-EIGRP-MIB: View SNMP OID List / Download MIB

Enhanced Interior Gateway Protocol (EIGRP) is a Cisco proprietary distance vector routing protocol. It is based on the Diffusing Update Algorithm (DUAL), which is a method of finding loop-free paths through a network. Directly connected routers running EIGRP form neighbor adjacencies in order to propagate best-path and alternate-path routing information for configured and learned routes. The tables defined within the MIB are closely aligned with how the router command-line interface for EIGRP displays information on EIGRP configurations, i.e., the topology table contains objects associated with the EIGRP topology commands, and the peer table contains objects associated withe EIGRP neighbor commands, etc. There are five main tables within this mib: EIGRP VPN table Contains information regarding which virtual private networks (VPN) are configured with EIGRP. EIGRP traffic statistics table Contains counter & statistcs regarding specific types of EIGRP packets sent and related collective information per VPN and per autonomous system (AS). EIGRP topology table Contains information regarding EIGRP routes received in updates and originated locally. EIGRP sends and receives routing updates from adjacent routers running EIGRP with which it formed a peer relationship. EIGRP peer (neighbor) table Contains information about neighbor EIGRP routers with which peer adjacencies have been established. EIGRP uses a Hello protocol to form neighbor relationships with directly connected routers also running EIGRP. EIGRP interfaces table Contains information and statistics on each of the configured to run. RIB-scale ========== The Wide-Metrics feature calculates all metrics in 64-bit under named mode EIGRP. Since the RIB can only hold 32-bit, we divide the wide metrics by RIB-scale (range 1-255, default value 128) to convert it to a 32-bit value before assiging it to RIB metrics.

This notification is sent when EIGRP MD5 authentication is enabled on any interface and peer adjacencies are formed, and any adjacencies go down as a result of an authentication failure.

This notification is sent when a route in the topology table is stuck in an active state. During the query phase for a new route to a destination network, a route is described as being in the active state if when an alternate path is actively being sought, no replies are received to normal queries or stuck-in-active queries.

This notification is sent when any EIGRP peer adjacency goes down.

This table contains information on those VPN's configured to run EIGRP. The VPN creation on a router is independent of the routing protocol to be used over it.

The total number of EIGRP derived routes currently existing in the topology table for the AS.

Routes in a topology table for an AS are assigned serial numbers and are sequenced internally as they are inserted and deleted. The serial number of the first route in that internal sequence is called the head serial number. Each AS has its own topology table, and its own serial number space, each of which begins with the value 1. A serial number of zero implies that there are no routes in the topology.

The serial number that would be assigned to the next new or changed route in the topology table for the AS.

When alternate route query packets are sent to adjacent EIGRP peers in an AS, replies are expected. This object is the total number of outstanding replies expected to queries that have been sent to peers in the current AS. It remains at zero most of the time until an EIGRP route becomes active.

A dummy is a temporary internal entity used as a place holder in the topology table for an AS. They are not transmitted in routing updates. This is the total number currently in existence associated with the AS.

A value of true(1) indicates that that this route which is in active state (cEigrpActive = true(1)) has not received any replies to queries for alternate paths, and a second EIGRP route query, called a stuck-in-active query, has now been sent.
