BGP route dampening does not work on the backup Routing Engine when nonstop
active routing is enabled.
Nonstop active routing supports Layer 2 circuit and VPLS on both LDP-based and
RSVP-TE-based networks. Nonstop active routing support enables the backup Routing
Engine to track the label advertised by Layer 2 circuit and VPLS on the primary Routing
Engine, and to use the same label after the Routing Engine switchover.
in Junos OS Release 9.6 and later, nonstop active routing support is extended to the
Layer 2 circuit and LDP-based VPLS pseudowire redundant configurations.
Nonstop active routing supports Protocol Independent Multicast (PIM) with stateful
replication on backup Routing Engines. State information replicated on the backup
Routing Engine includes information about neighbor relationships, join and prune events,
rendezvous point (RP) sets, synchronization between routes and next hops, multicast
session states, and the forwarding state between the two Routing Engines.
NOTE: Nonstop active routing for PIM is supported for IPv4 on Junos OS
Release 9.3 and later, and for IPv6 on Junos OS Release 10.4 and later. Starting
with Release 11.1, Junos OS also supports nonstop active routing for PIM on
devices that have both IPv4 and IPv6 configured on them.
To configure nonstop active routing for PIM, include the same statements in the
configuration as for other protocols: the

NOTE: The clear pim join
mode commands are not supported on the backup Routing Engine when
nonstop active routing is enabled.
Nonstop active routing support varies for different PIM features. The features fall into
the following three categories: supported features, unsupported features, and
incompatible features.
