P2MP RSVP-TE LSP Statistics
When the matching is performed on a context, the user must enter the RSVP session name string
in the format "templateName-svcId" to include the LSP template name as well as the mVPN
VPLS/B-VPLS service ID as configured at the ingress LER. In this case, one or more P2MP LSP
instances signaled by the same ingress LER could be associated with the ingress statistics
configuration. In this case, the user is provided with CLI parameter max-stats to limit the
maximum number of stat indices which can be assigned to this context. If the context matches
more than this value, the additional request for stat indices from this context will be rejected.
Note: The rules when configuring an ingress statistics context based on template matching are the
following:
1. max-stats once allocated can be increased but not decreased unless the entire ingress
2. In order to delete ingress statistics context matching a template name, a shutdown is
3. An accounting policy cannot be configured or de-configured until the ingress statistics
4. After deleting an accounting policy from an ingress statistics context matching a template
If there are no stat indices available at the time the session of the P2MP LSP matching a template
context is signaled and the session state installed by the egress LER, no stats are allocated to the
session.
Furthermore, the assignment of stat indices to the LSP names that match the context will also be
not deterministic. The latter is due to the fact that a stat index is assigned and released following
the dynamics of the LSP creation or deletion by the ingress LER. For example, a multicast stream
crosses the rate threshold and is moved to a newly signaled S-PMSI dedicated to this stream. Later
on, the same steam crosses the threshold downwards and is moved back to the shared I-PMSI and
the P2MP LSP corresponding to the S-PMSI is deleted by the ingress LER.
