To see whether or not nonstop active routing is enabled, issue the
command. For BGP nonstop active routing, you can also issue the
command.
For more information about these commands, see the
When you enable nonstop active routing or graceful Routing Engine switchover and issue
routing-related operational mode commands on the backup Routing Engine (such as
,
show route show bgp neighbor
match the output of the same commands issued on the master Routing Engine. For
example, it is normal for the routing table on the backup Routing Engine to contain
persistent phantom routes that are not present in the routing table on the master Routing
Engine.
To display BFD state replication status, issue the

To track the progress of nonstop active routing synchronization between Routing Engines,
you can configure nonstop active routing trace options flags for each supported protocol
and for BFD sessions and record these operations to a log file.
To configure nonstop active routing trace options for supported routing protocols, include
the statement at the
nsr-synchronization
hierarchy level and optionally specify one or more of the
options:
[edit protocols]
bgp {
traceoptions {
flag nsr-synchronization <detail> <disable> <receive> <send>;
}
}
isis {
traceoptions {
flag nsr-synchronization <detail> <disable> <receive> <send>;
}
}
