Issue with core Juniper M routers

Hi

We are running a Juniper core network, mostly MX480s. They have dual Routing Engines, so if one fails the other takes over. The problem is that NNMi does not reconcile these as the same node. Each routing engine has its own IP and SNMP sysname attribute, so when a routing engine “flips” NNMi discovers new one and report the old one as down, and re-creates the new node with the node properties of the previous node.

E.g same physical device, NNMi discovers 2 nodes.

I have a workaround in mind but wondering if anyone has had this scenario and how its managed?

Cheers

Mick

Re: Issue with core Juniper M routers

Greetings,

 

You can always check if both of devices has set the same MAC address or also youy can always try to set specific node settings on each device and add this to important nodes and with this the nodes will be discovered as different devices. 

If need further information or explanation you can always see the deployment reference and help for administrators documents: 

KM02822979 Help for administrator

KM00839190 Help for operator 

KM02795889 Deployment reference 

Happy to help and hope you can find this information useful.

Re: Issue with core Juniper M routers

Hi There

thanks for the reply. i don't think that is going to solve the problem, its more of a discovery issue specific to a device model i think. I don't want NNMi to create 2 nodes, that is what its doing now and its causing an issue. the Juniper M router is a MPLS router with 2 routing engines, active/standby. the problem is that NNMi discovers the standby routing engine and adds it as a different node.
