Symptoms

Latency and/or packet loss is noticed for connections to/from one or both ODA nodes. I/O to mounted NFS shares may also seem slow. 
A trace route also highlights differences:

Second [problem] Node 

C:\>tracert oda2-1

Tracing route to oda2-1
over a maximum of 30 hops:

 1    <1 ms    <1 ms    <1 ms  10.xxx.4.5
 2    <1 ms    <1 ms    <1 ms  10.xxx.3.4

Trace complete.

C:\>tracert oda2-2

Tracing route to oda2-2
over a maximum of 30 hops:

 1    <1 ms    <1 ms    <1 ms  170.xxx.66.11
 2      9 ms    99 ms     99 ms  10.xxx.64.59

Trace complete.

I have also included the ifconfig:
