22. OSPF6
OSPF for IPv6 is described in IETF
. The fundamental mechanisms of OSPF (flooding, DR election, area
support, SPF calculations, etc.) remain unchanged. However, some changes have been necessary, either due to
changes in protocol semantics between IPv4 and IPv6, or simply to handle the increased address size of IPv6.
All of OSPF for IPv4's optional capabilities, including on-demand circuit support, NSSA areas, and the multicast
extensions to OSPF are also supported in OSPF for IPv6. OSPF for IPv6 runs per-link instead of the IPv4 behavior
of per-IP-subnet.
Configuration
Global Configuration
This page displays the OSPF6 Global Configuration table. It is a general group to configure the OSPF6 common
router parameters.
OSPFv3 is the Open Shortest Path First routing
for IPv6. It is similar to OSPFv2 in its concept of a link
state database, intra- and inter-area, and AS external routes and virtual links.

Parameter descriptions
:
OSPF6 Router Mode
: Enable or Disable the OSPF6 router mode.
Router ID
: The OSPF6 Router ID in IPv4 address format (A.B.C.D). When the router's OSPF6 Router ID is
changed, if there is one or more fully adjacent neighbors in the current OSPF6 area, the new router ID will take
effect after restart OSPF6 process.
Note
that the router ID should be unique in the Autonomous System and that
the value '0.0.0.0' is invalid since it is reserved for the default algorithm.
Auto
: The default algorithm will choose the largest IP address assigned to the router.
Specific
: User specified router ID. The valid range is from 0.0.0.1 to 255.255.255.254.
Static Redistribute
: Whether the OSPF redistribute function is enabled for the static routes. Static routes are
manually-defined (remote) routes.
Enable
: The static routes are redistributed.
Disable
: The static routes are not redistributed
Connected Redistribute
: The OSPF redistribute enabled for connected route or not. Connected = RIP routes
that correspond to defined IP interfaces on which RIP is not enabled (defined locally). By default, the RIP Routing
Table only includes routes that correspond to IP interfaces on which RIP is enabled.
Enable
: The connected interfaces are redistributed.
Disable
: The connected interfaces are not redistributed (the default setting).
Administrative Distance
: The OSPF6 administrative distance in hops.
