Re: Node and CC ID types in LMP
Bakhta,
OIF's UNI allows for (IP) CCID to be either unnumbered (Node ID &
IF_Index) or numbered and allows for Node ID (ie UNI-C or UNI-N ID)
to be either IPv4 (or IPv6 but let for next UNI version(s)). So I
don't know where you found that the Node ID can be an NSAP in
this doc...
Per OIF UNI:
"An IPCC may be numbered, in which case it is identified by an IPv4
address at each end. If it is unnumbered then it is identified by the
combination of the Node ID and an interface index at each end. In the
case of numbered IPCC, migration to IPv6 addressing will depend on the
proliferation of IPv6 capable UNI-C and UNI-N nodes."
[...]
"Under UNI 1.0, the Node ID is an IPv4 address, which must be unique
within the domain of operation of the communicating UNI-C and UNI-N
nodes." [...] "Migration to IPv6 addressing for the Node ID will depend
on the proliferation of IPv6 capable UNI-C and UNI-N nodes".
So numbered IPCC would have (for future UNI version) to encompass
IPv6 addressing as well.
However, in LMP I-D, one defines the CCID as follows:
" Rather, a node-wide unique 32-bit non-zero integer control channel
identifier (CCId) is assigned at each end of the control channel. This
identifier comes from the same space as the unnumbered interface Id."
Therefore only the Node_ID would need to allow IPv6 in addition to what
is currently defined in LMP I-D.
Cheers,
