Source IP
Address
A single IP address is
assigned to the interface
transmitting IP traffic. For
details, see “Establishing an
IPoE connection for IPv4 traf-
fic” on page 122.
Two IP addresses are
assigned:
– Link-local address. this
source address is
assigned locally, and must
always go through dupli-
cate address detection
(DAD).
– Global address. This sec-
ond source address is not
used locally; it is used to
transmit traffic beyond the
router.
See “Establishing an IPoE
connection for IPv6 traffic” on
page 124.

prioritization
Uses one of the following:
– Layer 2 VLAN or Q-in-Q
encapsulation.
– Layer 3 MPLS encapsula-
tion which uses labels and
tunnel priorities.
Uses the following:
– VLAN or Q-in-Q encapsu-
lation.
– Flow labels. The HST
allows you to configure
traffic with flow labels sim-
ply to determine whether
routers on the circuit sup-
port the labels. See the
explanation provided for
the “Flow Label” setting on
page 141.
– MPLS encapsulation is not
supported.

Checksums
Checksum error insertion sup-
ported. See the Error Type
Table on
page 82 for valid
error types.
Does not use checksums. See
the Error Type Table on
page 82 for valid error types.
