Mpls - Juniper JUNOSE SOFTWARE 10.2.2 - RELEASE NOTES 6-4-2010 Release Note

Release 10.2.2
The clear ip mobile binding nai @realm command does not work. [Defect ID
178652]
Work-around: Use the following version of the command instead:
clear ip mobile binding nai user@realm
The setup rate for Mobile IP client sessions decreases when you repeatedly
bring a large number of sessions down and back up. [Defect ID 178760]
When mobility bindings are present and you delete the Mobile IP home agent
with the no virtual router command, Mobile IP sends a RADIUS Acct-Stop
message with no accounting statistics for the subscribers. [Defect ID 179081]
Work-around: Issue the clear ip mobile binding all command before you
issue the no virtual router command. The clear command clears all the MIP
subscribers and sends a RADIUS Acct-Stop message with the appropriate
accounting statistics for the subscribers.

MPLS

When MPLS and IS-IS are configured on Ethernet interfaces, you cannot delete
the interface after the IP address is removed. This issue is not a problem on
Ethernet VLAN interfaces. [Defect ID 66813]
Work-around: Issue the no mpls command to disable MPLS, then delete the
interface.
You cannot use an underscore character (_) in an MPLS tunnel name. [Defect ID
31291]
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]
