request that other BGP VPLS PE routers insert a control word between the label stack

and the MPLS payload.

Multicast

•

IGMP and PIM snooping support (MPC3E and MPC4E on MX240, MX480, and

MX960)—Starting with Junos OS Release 13.3, IGMP snooping and PIM snooping are

supported on the MX240, MX480, and MX960 and with Modular Port Concentrators

(MPC) MPC3E and MPC4E.

Network Management and Monitoring

•

BFD session enhancements (MX Series routers with MPCs or MICs)—Starting in

Junos OS Release 13.3, the following BFD session enhancements have been introduced:

•

enhanced-ip option—For BFD over aggregated Ethernet (ae) interfaces, configuring

the enhanced-ip option at the [edit chassis network-services] hierarchy level increases

the number of BFD sessions. When you activate or deactivate this option, the router

must be rebooted.

•

Inline mode—This enables the router to transmit and receive BFD packets from the

FPC hardware. Currently, for BFD over aggregated Ethernet (ae) interfaces, the inline

mode is supported only on MX Series routers with MPCs/MICs that have configured

the enhanced-ip option. For BFD over Gigabit Ethernet interfaces and VLAN interfaces,

the inline mode is supported by default on all the MX Series routers with MPCs/MICs.

•

Unified ISSU timer negotiation—During unified ISSU, the timer for BFD sessions is

increased from the configured value to 60 seconds.

•

Support for BFD over child links of AE or LAG bundle (cross-functional Packet

Forwarding Engine/kernel/rpd) (M Series, MX Series, and T Series)—Beginning in

Junos OS Release 13.3, BFD over child links of an AE or LAG bundle is supported. This

feature provides a Layer 3 BFD liveness detection mechanism for child links of the

Ethernet LAG interface. You can enable BFD to run on individual member links of the

LAG to monitor the Layer 3 or Layer 2 forwarding capabilities of individual member

links. These micro BFD sessions are independent of each other despite having a single

client that manages the LAG interface. To enable failure detection for aggregated

Ethernet interfaces, include the bfd-liveness-detection statement at the [edit interfaces

aex aggregated-ether-options bfd-liveness-detection] hierarchy level.

[See Understanding Independent Micro BFD Sessions for LAG.]
