> #### BGP

> - SRP 320 reset: reset type: panic; task: bgp; file: bgpPrefix.cc. This problem occurs when a router is configured with BGP signalling for VPLS and the BGP peer sends updates for the L2VPN prefix with a block offset set to 0. [Defect ID 91706]
> - High SRP CPU utilization because of BGP. [Defect ID 91868]

> #### DHCP

> - In the output of the show subscribers ipv6 command, the IPv6 Interface Id field, which denotes the EUI-64 IPv6 address of the subscriber's interface, always displays 0:0:0:0 and the Type field, which denotes the type of the subscriber, always displays unknown for IPv6 subscribers. This problem occurs for IPv6 subscribers in both a dual-stack network that contains both IPv4 and IPv6 subscribers and an environment that contains only IPv6 subscribers. [Defect ID 91618]
> - The output of the show subscribers command displays Inconsistent and incorrect information for dual-stack interfaces on which IPv4 and IPv6 subscribers are logged in over VLAN subinterfaces. [Defect ID 91926]
> - Subscribers are not able to connect when the DHCP proxy client stops DORA (transmission of discovery, offer, request, and acknowledgment messages between the server and the client) process due to stale FSM/CSM entries [Defect ID 92037]

> #### DHCP External Server

> - The dynamic subscriber interface (DSI) column might be deleted after the client sends a rebind request with a different xid. [Defect ID 91484]

> #### Dynamic Connection Manager

> - Service manager reports deactivation or activation fails on every other service request for redirected HTTP sessions. [Defect ID 91749]

> #### Forwarding

> - L2TP mirror does not have the correct packet offset for transmitted data on ES2 10G LMs for L2TP subscribers. [Defect ID 91803]
> - GE/FE line modules reset due to ill-formed or oversized packets generated by the module facing Link ram issue-IFA fatal panic history: 43008 [Defect ID 91785]
> - ARP requests that are received on a VLAN subinterface in the administratively down state are forwarded to the interface controller for being processed. [Defect ID 90332]
> - After you configure fast reroute extensions to RSVP-TE to enable local protection for the ingress router of the primary LSP by using bypass tunnels, forwarding of IPv6 traffic to some of the labeled BGP routes or IPv6 destinations over ES2 10G LMs and ES2 4G LMs fails. [Defect ID 189451]

> #### GRE

> - After you perform a unified ISSU operation or a stateful SRP switchover, GRE tunnel interfaces configured on ES2 10G ADV line modules that function as shared tunnel-server ports do not appear. This problem occurs only if you configured the tunnel interface as the analyzer interface. [Defect ID 188593]

> #### Hardware

> - Redundant IOA on an ES2 4G LM displays the question mark "?" character in the output of the show hardware command when stateful SRP switchover operation takes place. There is no impact on the regular router processing. When the line module takes over any slot in the redundancy group, it displays the correct hardware. [Defect ID 92418]
> - ES2 10G ADV LM processor exception 0x300(data access: address not mapped (read attempt)) [Defect ID 91981]
> - Load balancing of IPv6 traffic with prefixes of lengths other than /128 does not occur properly on equal-cost multipath (ECMP) links configured on ES2 10G LMs. [Defect ID 189965]
> - Load balancing of IPv6 traffic with prefixes of lengths other than /128 does not occur properly on LAG interfaces and equal-cost multipath (ECMP) links configured on ES2 4G LMs and GE-2 LMs. [Defect ID 189885]
> - Load balancing of IPv6 traffic with prefixes of lengths other than /128 does not occur properly on access interfaces in a LAG bundle configured on an ES2 10G LM. [Defect ID 189966]
> - ES2 10G ADV LM reset; file: ic1Detector.cc; camClassifierInterfaceIngress: 1; sraPanics: 3072; ingressIxpMePanics: 134217728 [Defect ID 91863]
> - Add the option to take line cards experiencing link ram errors off line automatically. [Defect ID 91890]

> #### IP

> - System logging initialization with an unexpected UID value in the routerId.cfg file causes an indefinite system outage. [Defect ID 91528]
> - GE-HDE (2 ports) LM card reset type: panic, arg (0x1a9fcb5) file: ppp.cc line: 14230 [Defect ID 91947]
> - The SRP module on an E320 router resets when it receives a packet with an invalid IP-Option header. [Defect ID 92185]

> #### IPv6

> - When static routes with null 0 interfaces as the next hop addresses are configured, the SNMP walk of inetCidrRouteTable enters into a loop. [Defect ID 187366]

> #### IS-IS

> - In MPLS VPN environment, the slot erase command does not work properly when the configuration on the Gigabit Ethernet VLAN subinterface on the slot includes IS-IS and MPLS protocols. The command fails and the Telnet session from which the command is entered stops responding. [Defect ID 91295]

> #### L2TP

> - L2TP subscriber sessions that were previously established are disconnected when you perform a stateful SRP switchover operation in a scaled environment. [Defect ID 187454]
> - L2TP LAC: Hello control message with AVP reserved bits all set is responded by a wrong StopCCN Error code. [Defect ID 91289]

> #### MPLS

> - ES2 10G Uplink LM reset type: processor exception 0x68616c74 (halt) task: scheduler [Defect ID 91482]

> #### Policy Management

> - If a secure policy is already attached to subinterfaces when a DHCP subscriber logs in, the juniPacketMirrorSessionStart SNMP notification is not triggered. [Defect ID 92286]
> - During packet mirroring for secure IPv6 policies, if you configure SNMP secure packet mirroring traps, the traps do not contain any fields to include the IPv6 prefix. However, for IPv4 policies, the IPv6 address field is present in the packet mirroring traps. [Defect ID 189862]

> #### PPP

> - PPP fragmentation and PPP reassembly settings that were previously configured on the router are deleted after an upgrade operation. [Defect ID 189802]
> - The name of a virtual router (VR) configured as the authentication VR context using the ppp authentication virtual-router command is incorrectly displayed with a mismatching VR name in the PPP profile configuration section in the output of the show configuration and show profile commands. [Defect ID 89489]

> #### QoS

> - ES2 4G LM failure at file: c2QosAgentIcc.cc message: file fc2QosAgent.cc line 3173: Missing node for [if0xaec00fff TCG0] at lvl 1 [Defect ID 91889]
> - Only the headings for S-VLAN aggregate statistics and not the values for the data fields are contained in the bulk statistics (.sts) file. This problem occurs only when the manual method of data transfer and not the automated collection method. [Defect ID 187592]

> #### SNMP

> - The output of the show snmp command indicates a discrepancy between the counters displayed for the Get-Request PDUs and Get-Response PDUs fields when Get Bulk requests are used by the client to obtain the identifiers and values as a group rather than one value at a time. [Defect ID 92278]

> #### SRC Software and SDX Software

> - The SRC client does not send Request packets for additional client bindings after a network service interruption. The Request packets are sent only to the DHCP hosts that are in a steady state prior to the network outage and not for the hosts that are added while the network connection is down. [Defect ID 91737]
> - The proprietary JunosE Policy Information Base (PIB) attribute is not contained in the Enterprise SNMP Management Identifiers (JUNIPER-UNI-SMI) file. [Defect ID 90238]
> - Because of many stale entries in the SscDhcpHandleTable, the DHCP local server operating in equal-access mode does not lease IP addresses to clients correctly. [Defect ID 92199]
> - SRP reset: task: sshd; file: sshServer.cc; line: 683; last errno: 0x0; lr: SshServer::Daemon::taskMain [Defect ID 92343]

> #### SSH

> - While an SSH session is attempted to be established with the router, the SSH sessions are blocked and do not get cleared after the disconnect ssh sessionid command is entered. The output of the show users command does not display information about these blocked SSH sessions. [Defect ID 92159]

> #### System

> - The hold-off timer stops during its countdown in the middle and then restarts, causing increased time for the router to be booted when a .scr file is used to boot up the router. [Defect ID 91685]
> - An error message is not displayed while the copy running-configuration command is used to copy the current configuration on the router to a script (*.scr) file. [Defect ID 90443]
> - A single space is present between the string "lag" and the name of the LAG bundle in the COPS handler messages that are sent. This behavior causes the policy manager to not service video-on-demand (VOD) requests properly. [Defect ID 189872]
> - Error log "hw2FabricDriver:Parity error on backpressure" msg coming up due to FPGA upgrade issue on standby SRP. [Defect ID 190012]
> - Unable to copy standby-disk0:system.log get error: Copy source does not exist or is unreachable. [Defect ID 90230]

> #### TCP

> - The security system logging message is generated at the info severity level with the label "couldn't allocate vty (no vtys are available)" even when virtual TTY (VTY) lines are available to be assigned for Telnet, SSH, or FTP services. [Defect ID 190135]
