The MPLS WG Archive

[Arun Satyanarayana <arun@gl.umbc.edu>]

Hi Tom and co.,

Regarding draft-ietf-mpls-te-mib-10.txt, please make some clarifications
on how the configured parameters map to signalling:

mplsTunnelIndex
Please add to the description to say how this maps to signaled objects.
Something like...
"For tunnel LSPs signaled using RSVP-TE, this value should correspond to
the Tunnel Id used for the RSVP-TE session."

mplsTunnelInstance
Description says...
"For tunnel LSPs signaled using RSVP, this value should correspond to the
RSVP source port used for the RSVP-TE session."
There is no such field in RFC3209. Please change to say...
"For tunnel LSPs signaled using RSVP-TE, this value should correspond to
the LSP-ID used for the RSVP-TE sender."

mplsTunnelIngressLSRId
Surely this should be the source of the tunnel not the extended tunnel id.
The description starts off right but goes wrong when it says...
"When the MPLS signalling protocol is rsvp(2) this value SHOULD mimic the
Extended Tunnel Id field in the SESSION object."
Please change this to say...
"When the MPLS signalling protocol is rsvp(2) this value should correspond
 to the Tunnel Sender Address in Sender Template."

mplsTunnelIngressLSRId and mplsTunnelEgressLSRId
Why is there no support for IPv6 source and destinations?

mplsTunnelDescr
Since this attribute cannot be signaled, please add a note to explain that
the value of this object at transit and egress nodes will be automatically
generated (or blank) according to the implementation and may not match the
value at the ingress.

mplsTunnelSessionAttributes
It would be helpful if these bits more closely matched the signaled
Session Attribute flags from RFC3209 and so on. It is also helpful to have
flags for triggering separate qualities of the tunnel. So... fastReroute
(0) is useful but should be split into fastRerouteNodeProt and
fastRerouteBWProt. recordRoute(4) is useful but we also need
recordRouteLabels. Please state how each flag maps to a flag in the
Session Attribute object.

Thanks,
_arun_
