Services Applications
•
Enabling Layer 2 Protocol Tunneling (L2PT) support for VLAN Spanning Tree Protocol
(VSTP) and per-VSTP (MX Series routers with MPC/MICs) —Starting in Junos OS
Release 13.3, this feature enables L2PT support for VSTP/PVSTP.
[See layer2-control.]
You can also enable rewriting of the MAC address for an interface using the
enable-all-ifl option.
[See mac-rewrite.]
•
Chained composite next hops (MX Series and T Series)—Starting in Junos OS Release
13.3, the support of chained composite next hops for directly connected provider edge
(PE) routers varies from one platform to another. On MX Series routers containing both
DPC and MPC FPCs, chained composite next hops are disabled by default. To enable
chained composite next hops on the MX240, MX480, and MX960, the chassis must
be configured to use the enhanced-ip option in network services mode. On T4000
routers containing MPC and FPCs, chained composite next hops are disabled by default.
To enable chained composite next hops on a T4000 router, the chassis must be
configured to use the enhanced-mode option in network services mode.
•
Data plane inline support added for 6rd and 6to4 tunnels connecting IPv6 clients
to IPv4 networks on MX Series routers with MPC line cards—Starting with Release
13.3R3, Junos OS supports inline 6rd and 6to4 on Modular Port Concentrator (MPC)
line cards with Trio chipsets, saving customers the cost of using MS-DPCs for the
required tunneling, encapsulation, and decapsulation processes. Anycast is supported
for 6to4 (next-hop service interfaces only). Hairpinning is also supported for traffic
between 6rd domains.
There are no CLI changes for 6rd and 6to4 configurations. To implement the inline
functionality, configure service interfaces on the MPC card as inline services interfaces
(si-) rather than as MultiServices (ms-) interfaces.
Two new operational commands have been added: show services inline softwire
statistics and clear services inline softwire statistics.
•
IPsec invalid SPI notification (MX Series and T Series)—Starting in Junos OS release
13.3R4, you can enable automatic recovery when peers in a security association (SA)
become unsynchronized. When peers become unsynchronized, this can cause the
transmission of packets with invalid security parameter index (SPI) values and the
dropping of those packets by the receiving peer. You can enable automatic recovery
by using the new respond-bad-spi max-responses configuration statement, which
appears under the hierarchy level [edit services ipsec-vpn ike policy]. This statement
results in a resynchronization of the SAs.
The max-responses value has a default of 5 and a range of 1 through 30.
•
Support for RPM probes with IPv6 sources and destinations (MX Series routers with
MPCs)—Starting with Junos OS release 13.3R5, the RPM client router (the router or
switch that originates the RPM probes) can send probe packets to the RPM probe
server (the device that receives the RPM probes) that contains an IPv6 address. To
specify the destination IPv6 address used for the probes, include the target (url ipv6-url
