Description

This article outlines the procedural steps necessary to accurately pinpoint the specific route table that corresponds to Rt-index.

Symptoms

 

In certain scenarios, delays in writing route changes (additions/deletions) to the forwarding database may occur, typically due to extensive route modifications. The following logs may be observed:

 

ppcfpc-multi-svcs.elf: FDB :: Ipv4 route operation 2 failed. Rt_index 1801, As_index 620360, gateway 1747774317

 

 

Solution

To troubleshoot and pinpoint the specific instance or table responsible for these route changes, thereby isolating the problematic instance, it is necessary to identify the relevant route table. This can be achieved from the FPC shell.

 

labroot@Device-re0> start shell pfe network fpc1
