JUNOSe 11.0.1 Release Notes

Known Problems and Limitations
You cannot use an underscore character (_) in an MPLS tunnel name. [Defect ID
31291]
If LSPs are announced into IS-IS, then the IS-IS routes cannot be used for
multicast RPF checks, because LSPs are unidirectional. [Defect ID 28526]
Work-around:
Configure static RPF routes with native hops when LSPs are
autoroute announced to IGPs.
When the IPv4 explicit null label appears anywhere other than at the bottom of
the label stack, TTL expiration for this label is not handled correctly. As a result,
the
traceroute
command does not work correctly for LSPs that have the IPv4
explicit null label anywhere other than at the bottom of the label stack. [Defect
ID 76037]
When you upgrade the router to JUNOSe Release 7.1.0 or a higher-numbered
release from a release numbered lower than Release 7.1.0, remote ATM layer 2
over MPLS circuits (also known as MPLS shim interfaces) that use Martini
encapsulation are erroneously signaled with the control word attribute setting
“Control word is not preferred by default”. Because control words are required
for these MPLS shim interfaces, these circuits should instead be signaled with
the setting “Control word is preferred by default”. [Defect ID 87048]
Work-around:
To reinstate the proper setting (“Control word is preferred by
default”), remove the MPLS shim interface from the ATM subinterface and then
reconfigure it.
When you issue a
traceroute
or
trace mpls
command to trace the paths of
router packets over MPLS interfaces on an ES2 10G LM or ES2 10G Uplink LM,
the results include an extra unknown host. [Defect ID 174537]
Multicast
When you configure more than 10,219 outgoing interfaces (OIFs) on the same
ES2 10G LM in a single multicast group, the configuration of the multicast
group’s OIF membership from the SRP module to the line module exceeds the
size of a single message and is sent in fragments. Because of this
fragmentation, the ES2 10G LM generates the following error message: [Defect
ID 81768]
pc: 0x9e5c88: -> fatalPanic(void) offset: 0x8
Netflow
Flow sampling stops after a cold switchover on a router that is configured with
16 VRs and 32 interfaces per VR, when all flows are passing through the
configuration (32 flows per VR). [Defect ID 74477]
Work-around:
After the cold switchover is completed, reissue the
ip
flow-sampling-mode packet-interval 10
command on each VR, even though
the command is present in the configuration.
