RFC Editor, I propose to reject this Errata. There is no technical merit in changing the example on how one might possibly choose the 32bit number. This is a NIT , and does not affect implementations, nor service provider policies. the text "Prefix = The 32-bit prefix is a value assigned by the provider " is the main definition of how this 32 bit value is to be assigned.

While it can be derived from the IPv4 /32 Loopback address, it causes confusion when routers are configured with no IPv4. It is better to suggest using router-id used by LDP for calculating the LSR identifier. How is router-id calculated is outside the scope of this document.` > > Instructions: > ------------- > This errata is currently posted as "Reported".
