mpls_vrf_label¶
MPLS Static VRF label management.
This module manages VRF label decapsulation for traffic arriving at the switch (on any interface).
In this example, a static VRF label route is configured for MPLS traffic arriving at the switch with a top label of 16. This label is mapped to a corresponding VRF “foo”.
// Configures a static VRF label route
eos::mpls_vrf_label_t vrf_label(mpls_label_t(16), "foo");
mgr->mpls_vrf_label_set(vrf_label);
By configuring a static VRF label route, the switch will decapsulate traffic matching the specified top label and forward normally based on the inner protocol headers and the routes within the specified VRF. IPv4, IPv6, and MPLS are the only inner protocols presently supported. Static MPLS routes are only available within the ‘default’ VRF when the inner protocol is MPLS, the specified VRF is ignored.

mpls_vrf_label_mgr - #include <mpls_vrf_label.h>
A manager of ‘mpls static vrf-label’ configurations.
Create one of these via sdk object prior to starting the agent main loop. When your eos::agent_handler::on_initialized virtual function is called, the manager is valid for use.

-
virtual void
resync_init() = 0 Enter resync mode.
At this point the mpls_vrf_label_mgr will start tracking which routes you’ve added.
-
virtual void
resync_complete() = 0 Exit resync mode.
All VRF label routes in Sysdb that you haven’t re-added during this resync period will now be deleted.
-
virtual mpls_vrf_label_iter_t
mpls_vrf_label_iter() const = 0 Iterates over all the VRF label routes currently configured.
-
virtual mpls_vrf_label_t
mpls_vrf_label(mpls_label_t const &) const = 0 Returns the current configuration of a VRF label route
If no VRF label route exists, this returns an empty
mpls_vrf_label_t()
-
virtual void
mpls_vrf_label_set(mpls_vrf_label_t const &) = 0 Adds the specified VRF label route to the system configuration.
Either creates or updates a VRF label route (keyed by the label).
-
virtual void
mpls_vrf_label_del(mpls_label_t const &) = 0 Removes the VRF label route from the configuration.
If the specified label does not exist, no action is taken.
