JunosE 11.0.2 Release Notes

Known Behavior
MPLS
Martini circuits configured on the ES2 10G LM act as true layer 2 tunnels,
without modifying the layer 2 headers. For this reason, Martini VLAN retagging
is not currently supported.
If you are upgrading to Release 7.1.0 or a higher-numbered release from a
release numbered lower than Release 7.1.0, and have inter-AS option B or C
configurations, you must explicitly configure MPLS on all inter-AS links, as in
the following example:
host1#
configure terminal
host1(config)#
interface fastEthernet 2/0
host1(config-if)#
ip address
...
host1(config-if)#
mpls
If you do not explicitly configure MPLS on the links, the inter-AS feature will not
work properly.
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.
You cannot use an underscore character (_) in an MPLS tunnel name. [Defect
ID 31291]
Multicast
The
ip dipe sg-cache-miss
and
ipv6 dipe
commands are not intended or
supported for customer use, although they are visible in the User Exec and
Privileged Exec modes respectively. These commands are intended to be used
in a Juniper Networks internal lab environment for testing without a traffic
generator.
Do not configure a multicast group with more than 10,219 outgoing interfaces
(OIFS) on the same ES2 10G LM. 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
