Known Problems and Limitations

Release 10.2.2
Logical port 20 on the ES2-S3 GE-20 IOA is reserved for the hardware multicast
packet replication feature. Logical port 20 and the hardware multicast
replication feature are not supported on the ES2-S3 GE-20 IOA in this release.
[Defect ID 84727]
After an SRP stateful switchover completes on an ERX1410 router configured
with a single VPN routing and forwarding instance (VRF) and Network Address
Translation (NAT), the SRP module that becomes active after the switchover
resets. [Defect ID 180058]
IP interface statistics become inconsistent when a slot is reset, because some
traffic (such as control traffic) might be destined for the SRP module and is
therefore counted elsewhere. [Defect ID 26697]
The
ip route permanent
command does not work properly. [Defect ID 34303]
Work-around:
You can issue the
ip alwaysup
command to prevent the route
from being removed from the IP routing table after the interface is shut down.
IPSec
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]
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.
IS-IS
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.
