Specifications

•
In Ethernet OAM connectivity-fault-management, Junos OS default encodes MAID(MD
name and MA name) in character format. Currently only 43 octets are supported in
Junos OS for the MD + MA name. Junos OS needs to support maximum length of 44
octets for MAID per the standards. PR997834
•
When IEEE 802.3ah OAM link-fault management action profile is configured to define
event and the resulting action, the link might flap after it is brought down by an event
but brought up by other events erroneously. PR1000607
•
In scenario that MX Series routers serve as a L2TP network server (LNS) and
Point-to-Point Protocol (PPP) sessions through established L2TP tunnels, if malformed
or incomplete PPPoE packet is received, the jpppd process (daemon which is
responsible for PPP based protocol) might crash while stripping HDLC header.
PR1002164
•
During the test of login/logout of couple of thousands of PPPoE subscibers, pppoed
may crash by generating a core file. PR1041367
•
jpppd core dump at ../../../../src/bsd/lib/libthr/thread/thr_kern.c due to heap allocation
failure .PR1047660
Layer 2 Features
•
When the "filter-interfaces" is configured, if SNMP walk is executed, the l2cpd process
might in a dead loop. At that moment, if the router receives ARP request packet, it
might drop the packet due to high CPU utilization. So the router fails to learn MAC
address, the traffic forwarding will be affected. PR982447
•
When toggling VLAN tagging type from "flexible-vlan-tagging" to "vlan-tagging" or
vice versa, the integrated bridging and routing (IRB) MTU should be changed
accordingly. However the IRB MTU is not re-computed in this case, which might lead
to connectivity outage. PR928746
•
In MX Series Virtual Chassis scenario with LACP configuration. In rare condition, after
VC-M chassis powers down, the LACP state getting stuck in ATTACHED state, all traffic
carried over these affected access LAGs are blackholed. PR959041
•
After change the way of getting site ID of VPLS from fixed site-id to automatic-site-id
on one site while other sites are still using the fixed site-id in the network, the rpd
process might crash due to the site ID get by "automatic-site-id" may conflict to site
ID which were configured as fixed site ID on other sites. PR1054985
MPLS
•
RSVP graceful restart does not function for LSPs that have a forwarding adjacency
(FA) label-switched path (LSP) as a next hop. PR60256
•
For point-to-multipoint LSPs configured for VPLS, the "ping mpls" command reports
100 percent packet loss even though the VPLS connection is active. PR287990
•
In current Junos OS, lsping/lsptrace utilities have compatibility issue with other vendor
routers. Millisecond field might show huge value which result incorrect RTD calculated.
