<p><font face="Ubuntu">Hi Donald,</font></p>
<p><font face="Ubuntu">Hi forgot last week to discuss one
point. So, I prefer add it before forget it again.</font></p>
<p><font face="Ubuntu">It concerns the management of mpls
label space.</font></p>
<p><font face="Ubuntu">Up to know, we have LDP and BGP that
deal with MPLS labels. I'm preparing Segment Routing for
OSPF, and for IS-IS. In Segment Routing, you must
specify at least one (but possibly many) Segment Routing
Global Block (SRGB) that reserved a block of labels.
Once done, Segment Routing allocates an MPLS label in
the SRGB for each router in the OSPF domain and a lable
per interface outside the SRGB. The issue is that we
must be sure that a) the SRGBs are reserved for Segment
Routing and not used by an other routing protoco, b)
that standard label allocation by the different routing
protocol are not overlapping SRGB and c) that label
allocation is unique i.e. a label is not used by more
than one routing protocol. I already discuss this point
with Renato last summer and re-activate this issue after
a call with peoples interested by Segment Routing that
Lou introduce for me.</font></p>
<p><font face="Ubuntu">So that, I would discuss the best way
to manage MPLS labels spaces to avoid overlapping of
label. I think about 3 scenarios:<br>
</font></p>
<p><font face="Ubuntu">1/ By means of configuration. Simple,
but report the issue to the user</font></p>
<p><font face="Ubuntu">2/ At the zebra layer. More dynamic,
but need to add extra message and code to zebra API</font></p>
<p><font face="Ubuntu">3/ At Linux Kernel. Not sure it is
the right place.</font></p>
<p><font face="Ubuntu">Regards</font></p>
