The configuration of R2 is as follows: Interface Serial0/0 ipv6 enable Router ospf1 Neighbor 2002::2 remote-as 12 address-family ipv6 ! Image The configuration of R2 is as follows (basic configuration and OSPFv3 ): CISCO IOS does not yet support tunnel servers. Of course, this time 1.1.1.0 is unable to access 3.3.3.0 , because R3 does not have a route in the RIP routing domain (that is, there is a problem with the backhaul routing, data communication must always consider the round-trip path, remember),brain dump ccna, so if To achieve network-wide interworking, you need to be on R2 : Prefixed with FEC0 : /10 . The first 10 bits are fixed at 1111111011 , followed by 0 consecutive 38 bits . Therefore, for site-local addresses, the first 48 bits are always fixed. There is a 16bits subnet ID field between the interface ID and the high 48bits specific prefix for the organization to build the subnet internally. Site-local addresses are not automatically generated and are manually configured.
