have the sum of te-metric of IGP with highest credibility at each hop in ERO. This has
been corrected and the cspf-metric will be sum of te-metric of current credibility at
each hop. PR1021593

When RSVP label-switched-path (LSP) optimize is enabled, RSVP LSP might stay
down after a graceful Routing Engine mastership switchover (GRES). To resolve the
problem, the corresponding label-switched-path configuration needs to be deactivated,
then, be activated again. PR1025413

Mib2d cores while trying to re-add a lag child into the patricia tree. Since the entry is
already present in the patricia tree. Before adding the child link mib2d does a lookup
on the tree, to know if the entry is not already there. However, this lookup returns no
results, since the child link is part of snmp filter-interface configuration. PR1039508

•
When apply-groups are used in the configuration, the expansion of interfaces <*>
apply-groups will be done against all interfaces during the configuration validation
process, even if the apply-group is configured only under a specific interface stanza.

The GNU debugger, gdb, can be exploited in a way that may allow execution of arbitrary
unsigned binary applications. PR968335

On MX series routers with MX Series linecards in a setup involving Packet Forwarding
Engine fast reroute (FRR) applications, if an interface is down for more than ARP
timeout interval or if ARP entries are cleared by cli commands, then after the interface
is up again packet forwarding issues may be seen for traffic being forwarded over that
interface. PR980052

Have BFD session between one router supporting inline-BFD (MX Series and Junos 13.3
or higher) and the other which does not support inline-BFD (any version and non-MX
Series, or MX Series and Junos <13.3). When the "failure detection time" is less than
50ms, the BFD session might flap. PR982258

On MX2020/MX2010 we might see sporadic FO request time-out error reported under
heavy system traffic load. This would mean the request returning into a grant took
longer then +/-30usec. The packet will still get forwarded through the fabric hence no
operational impact. [May 6 18:56:59.174 LOG: Err] MQCHIP(2) FO Request time-out
error [May 6 19:33:47.555 LOG: Info] CMTFPC: Fabric request time out pfe 2 plane 6

On MX Series router with MX Series linecard or T4000 router with type5 FPC, there
are 4k GRE tunnels with different MTU value. When the packets go through GRE tunnel,
if the packets size more than tunnel MTU, in rare condition, the GRE interface might
get stuck due to packets reassembling failure. PR993903
•
When receiving traffic coming on MPC and going out on DPC, the MAC entry on a Packet
Forwarding Engine might not be up-to-date and the frames targeted to a known MAC
address will be flooded across the bridge domain. PR1003525
