This output shows that nonstop active routing (Stateful Replication) is enabled on master
routing engine. If nonstop routing is not enabled, instead of the output shown above:
On the backup routing engine the following error message is displayed: "
routing subsystem is not running
On the master routing engine, the following output is displayed if nonstop routing is
not enabled:
Stateful Replication: Disabled
RE mode: Master
To troubleshoot nonstop active routing, perform these tasks:
Investigating Problems with Synchronization of Routing Engines When NSR Is
Enabled
A protocol loses connectivity with neighbors after a graceful Routing Engine switchover
(GRES) occurs with nonstop active routing (NSR) enabled.
Use trace options to help isolate the problem and gather troubleshooting information.
Using the information gathered from trace options, you can confirm or eliminate the
synchronization of the Routing Engines as the cause of the loss of connectivity for the
protocol. See "Tracing Nonstop Active Routing Synchronization Events" on page 1191.
