Interfaces on Cisco ASR Routers incorrectly discovered

    Description

      We just found out that Observium on our Cisco ASR routers mistakenly discovered some interfaces as tunnel interfaces. But they are common Gigabit interfaces. In the discovery process they are read correctly by the port module. The problem seems to arise with the IP address module. An excerpt from the discovery log is shown in the attachment. The ifIndex 49 and 53, for example, are affected here.

      Unfortunately, we cannot say exactly when the problem occurred. Observium runs in any case on the most current state: 19.5.9890 (rolling)

          I'm sure, there is just another Cisco issue, and probably need open Cisco TAC.

          But for correctly checking, please attach debug for discovery:

          ./discovery.php -d -m ports,ip-addresses -h <device>
