Enhancement to CSPF traceoptions—In Junos OS Release 10.3 and later, the
Constrained Shortest Path First (CSPF) trace messages have been updated to provide
more detailed information about CSPF path computation and rejection. You configure
the CSPF traceoptions by including the cspf flag at the [edit protocols mpls traceoptions
flag] hierarchy level. The following list shows some of the enhanced CSPF trace
messages (depending on your network configuration, the type of messages you see
might be different):

Platform and Infrastructure
•
Enhancement to show interfaces command—The show interfaces command includes
a new field, INET6 Address flags, that displays a flag for any IPv6 address that is in a
state other than “permanent” or “ready-to-use.”

Routing Protocols
•
New community-count routing policy match condition for BGP routes—You can now
configure the number of BGP community entries required for an incoming route to
match. This allows you to accept BGP routes based on a specific number of or range
of BGP community entries. To configure the number of community entries, specify the
from statement and include the community-count value (equal | orhigher | orlower)
match condition statement at the following hierarchy levels:
