show ip route variance
Detects the routes that are missing from the RIB, kernel, and data plane table and stores the discrepancy in a file.
Operational mode
Detects the routes that are missing from the RIB, kernel, and data plane table and stores the discrepancy in the following file: /home/<username>/vyatta_rtvariance.output. A missing route is identified by using codes such as R for RIB, K for kernel, and D for data plane. This command verifies only active routes and interfaces and can help during debugging.
Note: Ciena recommends that you use the command in a stable environment to ensure that you do not get wrong results. The vRouter may take more time to generate the output if the system has millions of routes.
The following example shows how to store the discrepancy in the following file: /home/vyatta/vyatta_rtvariance.output. The following output indicates that an IPv4 route is missing from the kernel.
vyatta@vyatta# show ip route variance
Output is dumped in the file: /home/vyatta/vyatta_rtvariance.output
