Known Problems and Limitations
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]
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]
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]
When the LAC–to–LNS data path runs over an MPLS tunnel and the MPLS
tunnel originates or terminates at the LAC on an ES2 10G LM or an ES2 10G
Uplink LM, the L2TP data traffic that originated or terminated at the LAC is
discarded. [Defect ID 87260]
MLDv2 proxy is not supported. [Defect ID 46038]
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 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 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.
