Device Specific (indicated by a host icon)

Use a device-specific value for the parameter. For device-specific parameters, you cannot enter a value in the feature template. You enter the value when you attach a Cisco SD-WAN device to a device template .

When you click Device Specific, the Enter Key box opens. This box displays a key,which is a unique string that identifies the parameter in a CSV file that you create. This file is an Excel spreadsheet that contains one column for each key. The header row contains the key names (one key per column), and each row after that corresponds to a device and defines the values of the keys for that device. You upload the CSV file when you attach a Cisco SD-WAN device to a device template. For more information, see Create a Template Variables Spreadsheet.

To change the default key, type a new string and move the cursor out of the Enter Key box.

Examples of device-specific parameters are system IP address, hostname, GPS location, and site ID.

Global (indicated by a globe icon)

Enter a value for the parameter, and apply that value to all devices.

Examples of parameters that you might apply globally to a group of devices are DNS server, syslog server, and interface MTUs.

Router ID

Enter the OSPF router ID in decimal four-part dotted notation. This is the unique 32-bit identifier associated with the OSPF router for Link-State Advertisements (LSAs) and adjacencies.

Distance for External Routes

Specify the OSPF route administration distance for routes learned from other domains.

Range: 0 through 255 Default: 110

Distance for Inter-Area Routes

Specify the OSPF route administration distance for routes coming from one area into another.

Range: 0 through 255 Default: 110

Distance for Intra-Area Routes

Specify the OSPF route administration distance for routes within an area.

Range: 0 through 255 Default: 110

Protocol

Choose the protocol from which to redistribute routes into OSPF. Choose from BGP, Connected, NAT, OMP, EIGRP and Static.

Route Policy

Enter the name of a localized control policy to apply to routes before they are redistributed into OSPF.

Area Number

Enter the number of the OSPF area.

Range: 32-bit number

Set the Area Type

Choose the type of OSPF area, Stub or NSSA.

No Summary

Click On to not inject OSPF summary routes into the area.

Translate

If you configured the area type as NSSA, choose when to allow Cisco IOS XE Catalyst SD-WAN devices that are ABRs (area border routers) to translate Type 7 LSAs to Type 5 LSAs:

• Always—Router always acts as the translator for Type 7 LSAs. That is no other router, even if it is an ABR, can be the translator. If two ABRs are configured to always be the translator, only one of them actually ends up doing the translation.

• Candidate—Router offers translation services, but does not insist on being the translator.

• Never—Translate no Type 7 LSAs.

Interface Name

Enter the name of the interface, in the format ge slot/port or loopback number.

Hello Interval

Specify how often the router sends OSPF hello packets.

Range: 1 through 65535 seconds Default: 10 seconds

Dead Interval

Specify how often the Cisco IOS XE Catalyst SD-WAN device must receive an OSPF hello packet from its neighbor. If no packet is received, the Cisco IOS XE Catalyst SD-WAN device assumes that the neighbor is down.

Range: 1 through 65535 seconds Default: 40 seconds (4 times the default hello interval)

LSA Retransmission Interval

Specify how often the OSPF protocol retransmits LSAs to its neighbors.

Range: 1 through 65535 seconds Default: 5 seconds

Interface Cost

Specify the cost of the OSPF interface.

Range: 1 through 65535

Designated Router Priority

Set the priority of the router to be elected as the designated router (DR). The router with the highest priority becomes the DR. If the priorities are equal, the node with the highest router ID becomes the DR or the backup DR.

Range: 0 through 255 Default: 1

OSPF Network Type

Choose the OSPF network type to which the interface is to connect:

• Broadcast network—WAN or similar network.

• Point-to-point network—Interface connects to a single remote OSPF router.

• Non-broadcast—Point-to-multipoint.

Default: Broadcast

Passive Interface

Click On or Off to specify whether to set the OSPF interface to be passive. A passive interface advertises its address, but does not actively run the OSPF protocol. Default: Off

Authentication

Specify the authentication and authentication key on the interface to allow OSPF to exchange routing update information securely.

• Authentication Type

Choose the authentication type:

• Simple authentication—Password is sent in clear text.

• Message-digest authentication—MD5 algorithm generates the password.

• Authentication Key

Enter the authentication key. Plain text authentication is used when devices within an area cannot support the more secure MD5 authentication. The key can be 1 to 32 characters.

• Message Digest

Specify the key ID and authentication key if you are using message digest (MD5).

• Message Digest Key ID

Enter the key ID for message digest (MD5 authentication). It can be 1 to 32 characters.

• Message Digest Key

Enter the MD5 authentication key in clear text or as an AES-encrypted key. It can be from 1 to 255 characters.

Address

Enter the IP address and subnet mask, in the format prefix/length for the IP addresses to be consolidated and advertised.

Cost

Specify a number for the Type 3 summary LSA. OSPF uses this metric during its SPF calculation to determine the shortest path to a destination.

Range: 0 through 16777215

No Advertise

Click On to not advertise the Type 3 summary LSAs or Off to advertise them.

Reference Bandwidth

Specify the reference bandwidth for the OSPF auto-cost calculation for the interface.

Range: 1 through 4294967 Mbps Default: 100 Mbps

RFC 1538 Compatible

By default, the OSPF calculation is done per RFC 1583. Click Off to calculate the cost of summary routes based on RFC 2328.

Originate

Click On to generate a default external route into an OSPF routing domain:

• Always—Click On to always advertise the default route in an OSPF routing domain.

• Default metric—Set the metric used to generate the default route.

  Range: 0 through 16777214 Default: 10

• Metric type—Select to advertise the default route as an OSPF Type 1 external route or an OSPF Type 2 external route.

SPF Calculation Delay

Specify the amount of time between when the first change to a topology is received until performing the SPF calculation.

Range: 0 through 600000 milliseconds (60 seconds) Default: 200 milliseconds

Initial Hold Time

Specify the amount of time between consecutive SPF calculations.

Range: 0 through 600000 milliseconds (60 seconds) Default: 1000 milliseconds

Maximum Hold Time

Specify the longest time between consecutive SPF calculations.

Range: 0 through 600000 Default: 10000 milliseconds (60 seconds)

Policy Name

Enter the name of a localized control policy to apply to routes coming from OSPF neighbors.
