Known Problems and Limitations
In a network where you use the tunnel signalling command to specify that the
security parameters and keys are configured manually for IPSec tunnels
between VRs, the line modules reset when you delete and then re-create the
IPSec tunnels. If you attempt to configure the tunnels again after the modules
come back up, the line modules reset again.
Work-around: Configure the IPSec tunnels to use ISASKMP/IKE to negotiate SA
and establish keys. [Defect ID 178304]
IPSec tunnels created over Fast Ethernet interfaces fail to come up. [Defect ID
179256]
Work-around: After you create the tunnel, bounce the tunnel interface by
issuing the shutdown/no shutdown command sequence. The tunnel comes up
successfully.
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]
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]
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]
