After a unified ISSU completes on a router functioning as an L2TP access

concentrator (LAC), traffic outages occur on the L2TP network server (LNS)-facing
interface at the LAC in a configuration with 16,000 or 32,000 L2TP sessions over 500
tunnels. [Defect ID 180147]
MLDv2 proxy is not supported. [Defect ID 46038]

The E Series router MLDv2 proxy does not operate correctly in the presence of MLDv1

queriers. [Defect ID 46039/46045]
Work-around: If an MLDv1 router is present on the network, configure version 1 with
the ipv6 mld-proxy version command on that network interface. (Version 2 is the
default.)
The default value for the MLDv2 proxy unsolicited report interval timer should be 1

second rather than 10 seconds (the value for v1). [Defect ID 46040]
The E Series router does not log a warning when it receives an MLDv1 query but is not

configured to use MLDv1 on the interface. [Defect ID 46046]
Failure to meet all of the following conditions for fragmented packets can result in an

incorrect operation during packet classification of the resulting reassembled packet:
[Defect ID 50111]
 The initial fragment of a packet must either contain the entire MLPPP packet or
be greater than 128 bytes.
 The fragment size of the peer must not be lower than 128 bytes.
 The initial fragment of a packet must be larger than subsequent fragments of
that packet.
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]
The @realm variable and the @ keyword alone do not work for the show ip mobile

binding command. [Defect ID 178653]
Work-around: You can use the user@realm syntax instead to display the binding for
a specific user, as in this example:
host1#show ip mobile binding nai xyz@example.com
Alternatively, you can display the entire Mobile IP binding table by issuing the show ip
mobile binding command without additional options.
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]
