# Cisco EIGRP

Collection of Ciso EIGRP checks
*  *cisco_eigrp_as_info*: monitors the EIGRP AS status
*  *cisco_eigrp_interface*: monitors EIGRP enabled interfaces
*  *cisco_eigrp_peers*: monitors EIGRP peers (IPv4 only)
*  *cisco_eigrp_topology_table*: monitors the EIGRP topology table

## Check Info *cisco_eigrp_as_info*:

* *service*: this check creates one service per EIGRP AS
* *state*: **critical** if the EIGRP AS is not found
* *wato*: none
* *perfdata*: 
    * Neighbour count (count)
    * Hellos send (/s)
    * Hellos received (/s)
    * Updates send (count)
    * Updates received (count)
    * Alternate route queries send (count)
    * Alternate route queries received (count)
    * Reply packets send (count)
    * Reply packets received (count)
    * Acknowledgements send (count)
    * Acknowledgements received (count)
    * Highest number of packets in the input queue (count)
    * Packets dropped from the input queue (count)
    * Stuck in active (SIA) queries sent (count)
    * Stuck in active (SIA) queries received (count)
    * Routes in the topology table (count)
    * Outstanding replies expected to queries send (count)

## Check Info *cisco_eigrp_interface*:

* *service*: this check creates on service per EIGRP enabled interface and EIGRP AS
* *state*:\
    **critical** 
    *  if no authentication is configured on the interface
    *  if the EIGRP enabled interface is not found

    **waring** 
    *  if the EIGRP MD5 authentication configured on the interface (move to hmac-sha-256)
* *wato*: you can confgure on withch interface types the check should ignore the missing EIGRP authentication
* *perfdata*:
    * Peer count (count)
    * Reliable queue length (count)
    * Unreliable queue length (count)
    * Average smooth round trip time (ms)
    * Routing updates awaiting transmission (count)
    * Reliable multicasts send (count)
    * Unreliable multicasts send (count)
    * Unreliable unicasts send (count)
    * Reliable unicasts send (count)
    * Multicast exceptions received (count)
    * Conditional-Receive packets (count)
    * Suppressed acknowledgements (count)
    * Retransmissions send (count)
    * Out-of-sequence packets received (count)

## Check Info *cisco_eigrp_peers*:

* *service*: this check creates on service per EOGRP peer interface and EIGRP AS  (IPv4 and IPv6)
* *state*:\
    **critical** if the EIGRP peer is not found
    **warning** if the EIGRP uptime less min uptime (default 86400 seconds)
* *wato*: **min uptime**: the time befor a peer is considered as stable, the default is 86400 seconds (1 day)
* *perfdata*:
    * Peer uptime (s)
    * Packets enqueued (count)
    * Retransmissions (count)
    * Retries (count)
    * Smooth round trip time (ms)
    * Retransmission timeout (ms)

## Check Info *cisco_eigrp_topology_table*:

* *service*: this check creates on service EIGRP AS
* *state*:\
    **critical** if the EIGRP table is not found\
    **warning** if SIA or active routes are found 
* *wato*: you can configure if the check should ignore SIA and/or active routes
* *perfdata*:
    * All routes (count)
    * Active routes (count)
    * Stuck in active (SIA) routes (count)
    * Connected routes (count)
    * Internal routes (count)
    * External routes (count)
    * Summary routes (count)
    * Static redistributed routes (count)
    * Inet address (count)
