EIGRP snmp and IPv6 Adresses

[otto.brandstaetter]

Hi!

we have just setup some tunnels using IPv6 only and now I am trying to monitor those tunnels using snmp.

Unfortunately pysnmp as well as check_eigrp (perl) are not so easy to use with IPv6.

So I am trying to work myself into this topic.

I am using snmpwalk to get states of the routers. Now, if I do a

snmpwalk -v 2c -c public -OT -m /var/lib/snmp/mibs/ietf/CISCO-EIGRP-MIB rt1iz  .1.3.6.1.4.1.9.9.449.1.4.1

I am getting some information, but I have trouble to decode the IPv6 hex-string:

CISCO-EIGRP-MIB::cEigrpPeerAddr.131072.100.1 = Hex-STRING: FE 80 00 00 00 00 00 00 12 05 CA FF FE 23 31 B0 [�.........���#1�]

Does anyone know how to decode this hex-string to a readable format?

Best regards and thanks in advance,

Otto

Hi @otto.brandstaetter ,

The hex string is the link local address (LLA) used to establish the eigrp neiborship.

FE80::1205:CAFF:FE23:31B0
