LSPs. To enable the polling and display of transit LSP statistics, include the

transit-statistics-polling statement at the [edit protocols mpls statistics] hierarchy

level. You cannot enable transit LSP statistics collection if MPLS statistics collection

is disabled with the no-transit-statistics statement at the [edit protocols mpls statistics]

hierarchy level.

Changes to MPLS protection options—In Junos OS releases prior to Release 13.3, you

can configure both fast reroute and node and link protection on the same LSP. Beginning

in Junos OS Release 13.3, you can still configure both fast reroute and node and link

protection on the same LSP; however, when you attempt to commit a configuration

where both features are enabled, a syslog warning message states: The ability to

configure both fast-reroute and link/node-link protection on the same LSP is deprecated

and will be removed in a future release.

PIM snooping support using relay mode (M Series and MX Series)—Starting with

Junos OS Release 13.3, PIM snooping on PE routers is supported using relay mode

instead of proxy mode. This enables CE routers with PIM snooping to send Hello packets

without setting the tracking bit (T-bit) to the PE routers. In relay mode, you need not

configure values for the join-prune-timeout statement and save the Finite State Machine.

To check the status of relay mode on the CLI, use the show pim snooping neighbors

command or the show pim snooping interfaces command.

•

Traffic arriving via IRB when configured in enhanced ip-mode—Beginning with Junos

OS Release 13.3, when configured in enhanced-ip mode, traffic arriving over IRB

(multic-ast source connected over Layer 3) is not forwarded to remote PEs in VPLS

when igmp-snooping is configured along with the use-p2mp-lsp statement.
