Support for non-volatile memory read-only (NVMRO). As a security feature unique to
the LN1000 Mobile Secure Router, NVMRO physically locks all non-volatile storage
against modifications. This includes the NAND system storage, the NOR boot flash,
and all Juniper Networks ID EEPROMS.
Support for advanced class-of-service (CoS) on Point-to-Point Protocol over Ethernet
(PPPoE) interfaces, which includes policing and shaping, weighted round robin (WRR)
queuing with prioritization, weighted random early detection (WRED), queuing based
on PPPoE interfaces, in addition to the supported VLAN/interface.
Support for up to eight ports of gigabit traffic with up to 1024 logical interfaces with
eight queues per logical interface and four priorities per queue. All eight ports interface
with the backplane. The LN1000 router supports most Layer 2 and Layer 3 protocols,
route redistribution, tunneling, multicast, routing, CoS, and security.
Support for location-based IP address pools for IPv4 addresses. A location pool can
specify IP addresses and subnet masks for multiple locations (relative positions of
cards within a shelf). You can configure an IP interface to obtain an IP address and
subnet mask from a selected location pool instead of specifying an explicit IP address
and subnet mask.
Support for PPPoE-based radio-to-router protocols. Extensions to the PPPoE protocol
include:
Messages that define how an external device provides the router with timely
information about the quality of a link connection
A flow control mechanism that indicates how much data the router can forward
The router uses the information provided in these PPPoE messages to dynamically
adjust the interface speed of PPP links. When OSPF is notified of this change, it adjusts
the cost of the link and updates the routing tables accordingly.
Support for translation of Protocol Independent Multicast (PIM) join/prune messages
to Internet Group Management Protocol (IGMP) or Multicast Listener Discovery (MLD)
report/leave messages. To enable the use of IGMP or MLD to forward multicast traffic
across the PIM domains, you can configure the rendezvous point (RP) router that
resides between the edge domain and core domain to translate PIM join/prune
messages received from PIM neighbors on downstream interfaces into corresponding
IGMP or MLD report/leave messages. The router then transmits the report/leave
messages by proxying them to one or two upstream interfaces that you configure on
the RP router.
Support for Open Shortest Path First (OSPF) refresh and flooding reduction in stable
topologies, which facilitates OSPF scaling by reducing OSPF protocol traffic overhead
and maintains OSPF adjacencies and flood link-state advertisements (LSAs).
Junos OS on the LN1000 router supports many of the features that exist on the SRX
Series Services Gateways. For further information about these features, refer to the SRX
