FastEthernet1/0 Ip route 0.0.0.0 0.0.0.0 202.101.23.2 Ipv6 address FE80::FFFF:FE10:2 link-local ipv6 router isis IPv4 In the above configuration, we map the A node, that is, 2001:1::1 to the IPv4 network, and map it to the IPv4 of 202.101.100.100. Interface tunnel 0 Provide a better next hop address. If it is 0.0.0.0 , it means the way to publish this route.

Image 6to4 automatic tunnel V2 defaults to send v2 to receive v2 Then start configuring BGP4+ : Ip address 202.101.100.1 255.255.255.0 !

In v4 , the first and last addresses are reserved for the network number and broadcast number. In IPv6 , there is no more broadcast. And in fact the IPv6 address space is so large that VLSM is not particularly necessary. Image Ipv6 router rip RIPprocess exit This idea has been applied to dynamic routing protocols such as OSPF . Careful children's shoes will find that after you deploy route summarization in OSPF , it will automatically generate a summary route pointing to null0 locally . The reason is explained above. the same. The configuration of R1 is as follows At this point, take a closer look at R1 : ! Set ip next-hop 10.1.1.2 10.2.2.2 set ip next-hop verify-availability interface fast 1/0 Other uses Configuration command As defined in RFC2462 , plug and play utilizes RS and RA messages. Contains MTU , prefix information, etc. Y Configuration example Image Unassigned Age Network 10.1.34.4 0.0.0.0 area 0 FastEthernet1/0 Because IS-IS runs on top of the data link layer, that is, it runs on top of the link layer protocol and requires CLNP support. Therefore, IPv6 IS-IS cannot be used on a remote IPv6 network connected through a tunnel . Configuring a tunnel is a static IPv6 over IPv4 tunnel. 202.101.100.2 . Therefore R2 receive this IPv6 time packets,ccna dumps free 2019, packets match found on v4map this IPv6ACL , therefore the object of the IPv6 last address 32bits translated IPv4 format (this is the IPv4 destination address), and then from V4 out a address pool Replace the IPv6 address. perfect. Configuration example 1 ( -RIP in a single routing protocol environment ) After this command is configured, the prefix information on the interface cannot be used for stateless autoconfiguration by the host on the link. The host must use stateful autoconfiguration such as DHCPv6 to obtain the address. By default, this command is not configured, that is, the managed-config-flag is 0 , which means that the host can obtain the address through a stateless configuration. PC1#sh ipv int Interface ID is 64bits , according to IEEE 's EUI-64 specification 48 -bit MAC address into a 64 -bit interface ID . Match tag matches based on the tag of the route The configuration of R3 is as follows: RouterID Advanced features Tunnel agent Whether the hop limit of the IPv6 header of the RA packet is 255 . Because only 255 means that it is generated by the router in the local network. No bgp default ipv4-unicast bgp log-neighbor-changes Use MD5 with BGP4+ ! Valid lifetime is similar to dhcp in the Lease Time . If the address exceeds the valid lifetime , the node will set this address to inactive and then delete . Between the preferred time and the valid lifetime is called the deprecated state. This state is a buffer . It is probably a deprecated state. When the address reaches this time period, the address cannot be actively initiated. The connection can only be passively accepted. Connection, this is also designed to ensure the upper layer application, but after the valid lifetime time address becomes invalid , then any connection will be down .
