show ipv6 route variance

Detects the IPv6 routes that are missing from the RIB, kernel, and data plane table and stores the discrepancy in a file.

show ipv6 route variance

Operational mode

Compares the routes in the RIB, kernel, and data plane table, detects missing IPv6 routes, and stores the discrepancy in the following file: /home/<username>/vyatta_rtvariance.output. The discrepancy contains IPv6 routes and addresses that are missing from the RIB, kernel, or data plane table. 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/<username>/vyatta_rtvariance.output.

vyatta@vyatta# show ipv6 route variance
Output is dumped in the file: /home/vyatta/vyatta_rtvariance.output
