VPLS Feature Guide for EX9200 Switches

NOTE: In the VPLS documentation, the word router in terms such as PE router
is used to refer to any device that provides routing functions.
The point-to-multipoint LSP used for VPLS flooding can be either static or dynamic. In
either case, for each VPLS routing instance, the PE router creates a dedicated
point-to-multipoint LSP. All of the neighbors of the VPLS routing instance are added to
the point-to-multipoint LSP when the feature is enabled. If there are n PE routers in the
VPLS routing instance, n point-to-multipoint LSPs are created in the network where each
PE router is the root of the point-to-multipoint tree and includes the rest of the n – 1 PE
routers as leaf nodes. If you configured static point-to-multipoint LSPs for flooding, any
additional VPLS neighbors added to the routing instance later are not automatically
added to the point-to-multipoint LSP. You will need to manually add the new VPLS
neighbors to the static point-to-multipoint flooding LSP. If you configure dynamic
point-to-multipoint LSPs, whenever VPLS discovers a new neighbor through BGP, a
sub-LSP for this neighbor is added to the point-to-multipoint LSP for the routing instance.
This feature can be enabled incrementally on any PE router that is part of a specific VPLS
routing instance. The PE routers can then use point-to-multipoint LSPs to flood traffic,
whereas other PE routers in the same VPLS routing instance can still use ingress replication
to flood traffic. However, when this feature is enabled on any PE router, you must ensure
that all PE routers in the VPLS routing instance that participate in the flooding of traffic
over point-to-multipoint LSPs are upgraded to Junos OS Release 8.3 or later to support
this feature.
To flood unknown unicast, broadcast, and multicast traffic using point-to-multipoint
LSPs, configure the
rsvp-te
rsvp-te {
label-switched-path-template (Multicast)
(default-template | lsp-template-name);
}
static-lsp lsp-name;
}
You can include this statement at the following hierarchy levels:
[edit routing-instance routing-instance-name provider-tunnel]
[edit logical-systems logical-system-name routing-instances routing-instance-name
provider-tunnel]
You can configure either a static point-to-multipoint LSP for VPLS flooding or a dynamic
point-to-multipoint LSP.
NOTE: You cannot specify both the
statements at the same time.
