Reference Guide

– 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?
• Are you able to ping the link-local IPv6 address of adjacent router interface?
