Advanced configuration CE1 and CE2 configuration Image R2 the original IPv4 header packet replacing IPv6 header, and then transferred to A . Header format Vrf definition cisco rd 1:1 In the above example, the phenomenon we mentioned, R4 will know the route from OSPF and RIP to 192.168.1.0/24 , and finally R4 will choose OSPF route. This is a phenomenon we don't want to see in this environment, because it creates a sub-optimal path. The AD values ​​for several common routing protocols are listed below: 2) After the packet arrives at R2 , there is already a mapping in R2 local: 2001:1::1 maps to 202.101.100.100 Neighbor FE80::CE01:8FF:FED8:10 activate On R1 , ip route 1.0.0.0 255.0.0.0 null 0 then ip defaut-network 1.0.0.0 , then R2R3 will learn the default route technical background Ivv nd other-config-flag Now, on R3 , re-release the direct loopback route into BGP4+ After the completion, simply show it on R2 : :: Image Image On the other hand, after ISATAP is deployed on the router , the router also generates a tunnel interface to respond to the tunnel establishment request of the ISATAP host. The tunnel interface also generates the interface identifier. Address format is IANA reserved ISATAP of 32 bits Ipv6 dhcp server DHCP-pool Interface serial0/0 Look at the picture above: Routers A and B are two sites. Both sides apply for an IPv4 public network address, and use this public network IPv4 address to map to obtain the world's only 6to4 IPv6 address. This 6to4 IPv6 address /48 bit has a very large space and is used for IPv6 users in the site . Thus, when the site A in the IPv6 user accessing the site B in IPv6 user, IPv6 packet to A , then A according to the IPv6 destination data header IPv6 address, to obtain a corresponding IPv4 global the IP , then it will original The IPv6 packet is encapsulated, the IPv4 header of the 6to4 tunnel is placed, and then the packet is placed.IPv4 network routing,latest ccna dumps, until reaching B .
