Known Problems and Limitations
43
Release 11.1.1
IS-IS
z
On a router configured with IS-IS and BFD, using the
redundancy force srp
command
to force an SRP switchover sometimes brings down IS-IS and BFD. [Defect ID
179287]
z
IS-IS graceful restart (nonstop forwarding) does not work on the broadcast interface
when the restarting router is the designated intermediate system (DIS). Graceful
restart works properly when the restarting router is not the DIS. [Defect ID 61496]
L2TP
z
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]
MLD
z
MLDv2 proxy is not supported. [Defect ID 46038]
z
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.)
z
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]
z
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]
MLPPP
z
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.
Mobile IP
z
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
z
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
