Specifications

OpenFlow
•
Support for OpenFlow v1.0 (MX80, MX240, MX480, and MX960)—Starting with
Junos OS Release 13.3, the MX80, MX240, MX480, and MX960 routers support
OpenFlow v1.0. OpenFlow enables you to control traffic in an existing network using
a remote controller by adding, deleting, and modifying flows on a switch. You can
configure one OpenFlow virtual switch and one active OpenFlow controller at the [edit
protocols openflow] hierarchy level on each device running Junos OS that supports
OpenFlow. On MX Series routers that support OpenFlow, you can also direct traffic
from OpenFlow networks over MPLS networks by using logical tunnel interfaces and
MPLS LSP tunnel cross-connects.
[See OpenFlow Feature Guide.]
Platform and Infrastructure
•
Virtual Route Reflector (VRR)—Starting in Junos OS Release 13.3R3, you can implement
route reflector capability using a general purpose virtual machine on a 64-bit Intel-based
blade server or appliance. Benefits of the VRR are:
•
Improved scalability (depending on the server core hardware use)
•
Scalability of the BGP network with lower cost using VRR at multiple locations in
the network
•
Fast and more flexible deployment using Intel servers rather than router hardware
•
Space savings through elimination of router hardware
Port Security
•
Static ARP with multicast MAC address for an IRB interface—Starting in Junos OS
Release 13.3, you can configure a static ARP entry with a multicast MAC address for
an IRB interface that acts as the gateway to the network load balancing (NLB) servers.
Earlier, the NLB servers dropped packets with a unicast IP address and a multicast
MAC address. Junos OS Release 13.3 supports the configuration of a static ARP with
a multicast MAC address.
To configure a static ARP entry with a multicast MAC address for an IRB interface,
configure the ARP entry at the [edit interfaces irb unit logical-unit-number family inet
address address] hierarchy level.
irb {
unit logical-unit-number{
family inet {
address address{
arp address multicast-mac mac-add;
}
}
}
}
