Cisco Public 6 Router(config)# ipv6 unicast-routing A routers interfaces can be enabled (configured with an IPv6 address) for IPv6 like any other device on the network For the router to act as an IPv6 router it must be enabled with the ipv6-unicast routing command This enables the router to: Send ICMPv6 Router Advertisement messages Enable the forwarding of IPv6 packets Configure static routing and participate in IPv6 routing protocols (EIGRP for IPv6, OSPFv3) Similar to old ip routing command for IPv4 which is enabled by default

Cisco Public 13 Not routable Local route = similar to what we called a host route in IPv4 Host routes point to the routers IPv6 global unicast addresses The router uses these routes when the packets are addressed to one of its own interfaces Router can more efficiently process packet to itself Host routes in IPv6 will have /128 prefix L 2001:DB8:CAFE:1::1/128 [0/0] via ::, FastEthernet0/0 L 2001:DB8:CAFE:A001::1/128 [0/0] via ::, Serial0/0/0 L 2001:DB8:CAFE:A002::1/128 [0/0] via ::, Serial0/0/1 L FF00::/8 [0/0] via ::, Null0 L FF80::/10 [0/0] via ::, Null0
