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
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):

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
statement and include the
from
match condition statement at the following hierarchy levels:
[edit policy-options policy-statement policy-name term term-name]
