IPv6 filtering

• ipv6 41 IPv6 # IPv6 • ipv6-route 43 IPv6-Route # Routing Header for IPv6 • ipv6-frag 44 IPv6-Frag # Fragment Header for IPv6 • ipv6-crypt 50 IPv6-Crypt # Encryption Header for IPv6 • ipv6-auth 51 IPv6-Auth # Authentication Header for IPv6 • ipv6-icmp 58 IPv6-ICMP icmpv6 icmp6 # ICMP for IPv6 • ipv6-nonxt 59 IPv6-NoNxt # No Next Header for IPv6 • ipv6-opts 60 IPv6-Opts # Destination Options for IPv6 Ok filtering ipv6 and ipv6-icmp is understood, it is like ipv4. But what about the others, should they be blocked, restricted? Does a ios "deny ipv6 any any" affect them?
