To delete an IPsec area authentication policy, use the no area area-id authentication ipsec spi number command.

IPsec encryption for OSPV3 area
Prerequisite: Before you enable IPsec encryption for an OSPFv3 area, rst enable OSPFv3 globally on the router.
When you congure encryption at the area level, both IPsec encryption and authentication are enabled. You cannot congure encryption if
you have already congured an IPsec area authentication (area ospf authentication ipsec). To congure encryption, you must
rst delete the authentication policy.
• Enable IPsec encryption for OSPFv3 packets in an area in Router-OSPFv3 mode.
area area-id encryption ipsec spi number esp encryption-type key
authentication-type key
• area area-id — Enter an area ID as a number or IPv6 prex.
• ipsec spi number — Enter a unique security policy index (SPI) value (256 to 4294967295).
• esp encryption-type — Enter the encryption algorithm used with ESP (3DES, DES, AES-CBC, or NULL). For AES-CBC,
only the AES-128 and AES-192 ciphers are supported.
• key — Enter the text string used in the encryption algorithm. All neighboring OSPFv3 routers must share the 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.
• authentication-type — Enter the encryption authentication algorithm to use (MD5 or SHA1).
• key — Enter the text string used in the authentication algorithm. All neighboring OSPFv3 routers must share the 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 SHA-1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key is not supported.
To delete an IPsec encryption policy, use the no area area-id encryption ipsec spi number command.

Troubleshoot OSPFv3
You can troubleshoot OSPFv3 operations, as well as check questions for any typical issues that interrupt a process.
• Is OSPFv3 enabled globally?
• Is OSPFv3 enabled on the interface?
• Are adjacencies established correctly?
• Are the interfaces congured for L3 correctly?
• Is the router in the correct area type?
• Are the OSPF routes included in the OSPF database?
• Are the OSPF routes included in the routing table in addition to the OSPF database?
