Hi,
does this means IPsec is the only way to authenticate in OSPFv3?
I tried with the following and it worked:
R2#interface Ethernet0/0
no ip address
ipv6 address 2001::2/64
ospfv3 1 authentication key-chain CISCO
ospfv3 1 ipv6 area 0
R2#show ospfv3 ipv6
OSPFv3 1 address-family ipv6
Router ID 2.2.2.2
Active Key-chains:
Key chain CISCO: Send key 1, Algorithm HMAC-SHA-1, Number of interfaces 1
Area BACKBONE(0)
thanks
Edit: This post gives the idea that OSPFv3 does not support any authentication beside IPsec, but after checking it does support the usual MD5 and HMAC that I mentioned above.
Samer.
