Command Mode ROUTER-OSPFv3
Usage
Information
● Before you enable IPsec encryption for an OSPFv3 area, you must enable OSPFv3 globally on each
router.
● When you configure encryption at the area level, both IPsec encryption and authentication are
enabled. You cannot configure encryption if you have already configured an IPsec area authentication
using the area ospf authentication ipsec command. To configure encryption, you must first
delete the authentication policy.
● All OSPFv3 routers in the area must share the same encryption key to decrypt information. Only a
non-encrypted key is supported. Required lengths of the non-encrypted key are: 3DES — 48 hex
digits; DES — 16 hex digits; AES-CBC — 32 hex digits for AES-128 and 48 hex digits for AES-192.
● All OSPFv3 routers in the area must share the same authentication key to exchange information. Only
a non-encrypted key is supported. For MD5 authentication, the non-encrypted key must be 32 plain
hex digits. For SHA1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key is
not supported.
Example
OS10(config-router-ospfv3-100)# area 1 encryption ipsec spi 401 esp des

Releases
10.4.0E(R1) or later
area stub
Defines an area as the OSPF stub area.
Syntax
area area-id stub [no-summary]
Parameters
● area-id—Set the OSPFv3 area ID as an IP address in A.B.C.D format or number, from 1 to 65535.
● no-summary—(Optional) Prevents an ABR from sending summary LAs into the stub area.
Default Not configured
Command Mode ROUTER-OSPFv3
Usage
Information
The no version of this command deletes a stub area.
Example
OS10(config)# router ospfv3 10
OS10(conf-router-ospfv3-10)# area 10.10.1.5 stub
Supported
Releases
10.3.0E or later
auto-cost reference-bandwidth
Calculates default metrics for the interface based on the configured auto-cost reference bandwidth value.
Syntax
auto-cost reference-bandwidth value
Parameters value — Enter the reference bandwidth value to calculate the OSPFv3 interface cost in megabits per
second, from 1 to 4294967.
Default 100000
Command Mode ROUTER-OSPFv3
Usage
Information
The value set by the ipv6 ospf cost command in INTERFACE mode overrides the cost resulting from
the auto-cost command. The no version of this command resets the value to the default.
Example
OS10(config)# router ospfv3 100
OS10(config-router-ospfv3-100)# auto-cost reference-bandwidth 150
