ZXR10 ZSR V2 Configuration Guide (IPv6)
This is an 8-bit field and reserved for future use. It is likely to be used for extending
the top- or next-level aggregation identifier field.
à
NLA ID field
This is the next-level aggregation identifier with 24 bits. This identifier is used
by some institutions (including large-size ISPs and other institutions that provide
public network access) to control the top-level aggregation for address space
arrangement.
Such institutions can divide this 24-bit field for use in accordance with their own
addressing hierarchical structures. In this way, an entity can divide two bits of
address space into four internal top-level routes, and allocate the other 22 bits of
address space to other entities (for example, a small local ISP).
When these entities obtain enough address space, they can subdivide the obtained
space in the same way as mentioned above.
à
SLA ID field
This is the site aggregation identifier and is used by some institutions to arrange
their internal network structures. Each institution can create its own internal
hierarchical network structure in the same way as that of IPv4.
When the 16-bit field is dedicated to the plane address space, there are at most
65,535 different subnets available. If the first eight bits are used for the internal
advanced routing of this institution, then there will be 255 advanced subnets
available, and each advanced subnet can have up to 255 sub-subnets.
à
Interface identifier field
This is a 64-bit field, containing 64-bit values of the IEEE EUI-64 interface
identifier.
l
Special Address & Reserved Address
In the first 1/256 IPv6 address space, the first 8 bits 0000 0000 of all the addresses
are reserved. Most of the vacant address spaces are used for special addresses,
including:
à
Undesignated address
This is an all-zero address and is used if no valid address is available. For
example, if a host does not obtain an IPv6 address upon its initial startup from
the network, it can use this address. That is, it can specify this address for the
source address of the IPv6 packet when it sends out a request for configuration
information. This address can be expressed as 0:0:0:0:0:0:0:0, or expressed as
::.
à
Loopback address
In IPv4, the loopback address is defined as 127.0.0.1. Any packet that sends a
loopback address must be sent to a network interface through a protocol stack,
instead of being sent to the network link. The network interface itself should
