Configure OSPFv3

Configure general virtual router settings.
Configure general OSPFv3 configuration settings.
Select the
OSPFv3
tab.
Select
Enable
to enable the OSPF protocol.
Enter the
Router ID
.
Select
Reject Default Route
if you do not want to learn any default routes through OSPFv3 This is the recommended default setting.
Clear
Reject Default Route
if you want to permit redistribution of default routes through OSPFv3.
Configure Auth Profile for the OSPFv3 protocol.
While OSPFv3 doesn't include any authentication capabilities of its own, it relies entirely on IPSec to secure communications between neighbors.
When configuring an authentication profile, you must use Encapsulating Security Payload (ESP) (recommended) or IPv6 Authentication Header (AH).
ESP OSPFv3 authentication
On the
Auth Profiles
tab,
Add
a name for the authentication profile to authenticate OSPFv3 messages.
Specify a Security Policy Index (
SPI
) (hexadecimal value in the range from 00000000 to FFFFFFFF). The two ends of the OSPFv3 adjacency must have matching SPI values.
Select
ESP
for
Protocol
.
Select a
Crypto Algorithm
.
You can select
None
or one of the following algorithms:
SHA1
,
SHA256
,
SHA384
,
SHA512
, or
MD5
.
If a
Crypto Algorithm
other than None was selected, enter a value for
Key
and then confirm.
AH OSPFv3 authentication
On the
Auth Profiles
tab,
Add
a name for the authentication profile to authenticate OSPFv3 messages.
Specify a Security Policy Index (
SPI
). The SPI must match between both ends of the OSPFv3 adjacency. The SPI number must be a hexadecimal value between 00000000 and FFFFFFFF.
Select
AH
for
Protocol
.
Select a
Crypto Algorithm
.
You must enter one of the following algorithms:
SHA1
,
SHA256
,
SHA384
,
SHA512
, or
MD5
.
Enter a value for
Key
and then confirm.
Click
OK
.
Click
OK
again in the Virtual Router - OSPF Auth Profile dialog.
Configure Areas - Type for the OSPFv3 protocol.
On the
Areas
tab,
Add
an
Area ID
. This is the identifier that each neighbor must accept to be part of the same area.
On the
General
tab, select one of the following from the area
Type
list:
Normal
—There are no restrictions; the area can carry all types of routes.
Stub
—There is no outlet from the area. To reach a destination outside of the area, it is necessary to go through the border, which connects to other areas. If you select this option, configure the following:
Accept Summary
—Link state advertisements (LSA) are accepted from other areas. If this option on a stub area Area Border Router (ABR) interface is disabled, the OSPF area will behave as a Totally Stubby Area (TSA) and the ABR will not propagate any summary LSAs.
Advertise Default Route
—Default route LSAs will be included in advertisements to the stub area along with a configured metric value in the configured range 1-255.
NSSA
(Not-So-Stubby Area)—The firewall can leave the area only by routes other than OSPF routes. If selected, configure
Accept Summary
and
Advertise Default Route
as described for
Stub
. If you select this option, configure the following:
Type
—Select either
Ext 1
or
Ext 2
route type to advertise the default LSA.
Ext Ranges
—
Add
ranges of external routes that you want to enable or suppress advertising for.
Associate an OSPFv3 authentication profile to an area or an interface.
To an Area
On the
Areas
tab, select an existing area from the table.
On the
General
tab, select a previously defined
Authentication Profile
from the
Authentication
list.
Click
OK
.
To an Interface
On the
Areas
tab, select an existing area from the table.
Select the
Interface
tab and
Add
the authentication profile you want to associate with the OSPF interface from the
Auth Profile
list.
Click
OK
.
Click
OK
again to save the area settings.
(
Optional
) Configure Export Rules.
On the
Export Rules
tab, select
Allow Redistribute Default Route
to permit redistribution of default routes through OSPFv3.
Click
Add
.
Enter the
Name
; the value must be a valid IPv6 subnet or valid redistribution profile name.
Select
New Path Type
,
Ext 1
or
Ext 2
.
Specify a
New Tag
for the matched route, using has a 32-bit value in dotted-decimal notation.
Assign a
Metric
to the new rule (range is 1-16,777,215).
Click
OK
.
Configure Advanced OSPFv3 options.
On the
Advanced
tab, select
Disable Transit Routing for SPF Calculation
if you want the firewall to participate in OSPF topology distribution without being used to forward transit traffic.
Specify a value for the
SPF Calculation Delay (sec)
timer, which allows you to tune the delay time (in seconds) between receiving new topology information and performing an SPF calculation. Lower values enable faster OSPF re-convergence. Routers peering with the firewall should use the same delay value to optimize convergence times.
Specify a value for the
LSA Interval (sec)
timer, which is the minimum time (in seconds) between transmissions of two instances of the same LSA (same router, same type, same LSA ID). This is equivalent to MinLSInterval in RFC 2328. Lower values can be used to reduce re-convergence times when topology changes occur.
(
Optional
) Configure OSPF Graceful Restart.
