Configure RIP unicast updates: Dual stack host through HTTP obtained from the agent of the tunnel IPv4 and IPv6 addresses, these addresses then the end user to configure and enable the use of the tunnel, to which the obtained IPv4 address of the tunnel is the IPv4 address. NAT (Network Address Translation) X Image Prefix announcements are the initial mechanism for stateless autoconfiguration. Using RA ( ICMPv6 Type 134 ) and the multicast address of all nodes ( FF02::1 ), the router RA message is periodically sent to FF02::1 on the local link . Set ip next-hop verify-availability 10.1.1.2 10 track 1 CE1 and CE2 configuration Experimental example: Called when republishing In the above experimental environment, R2 and R3 establish a BGP neighbor relationship using the Linklocal address . R3 where AS300 the IPv6 prefixes, there are IPv4 routing prefix, to pass R2 . Router(config-rtr)# timers update expire holddown garbage-collect The IPv6 address used by the automatic IPv4 compatible tunneling mechanism is " IPv4- compatible IPv6 address". Match length matches according to the third layer length of the packet The uniqueness of the MAC address guarantees the uniqueness of the interface ID . Ip address 10.1.23.2 255.255.255.0 Basic knowledge 100.1.1.0/24 . At the same time, this re-release becomes the summary route of OSPF . Even if two ASBRs are returned , because there is a static summary route locally, the summary route of OSPF is directly ignored , and sub-optimal is not generated. Path, this route will not be re-released back to RIP and cause other problems. FastEthernet0/0 is up, line protocol is up R4#sh ip ro 192.168.1.0 Configure an interface as a passive interface: ! Image But on R1 : Ipv6 router ospf 1 router-id 1.1.1.1 Tunnel destination 10.1.23.3 Mpls ip There are two types of ICMP messages: error messages and information messages. Interface FastEthernet0/0 0 : Reserved; Image R3.00-00 Next , summarize the loopback route of R1 on R2 : As defined in RFC3053 , a tunneling agent is an external system, not a router. It acts as a server in an IPv4 network and accepts tunnel requests from dual-stack nodes. Interface The Advertisement message notifies the prefix information. The RA message contains information such as prefix, lifetime, and default gateway. The general process is shown in the figure below. For more details, please refer to the relevant sections of this document. Use route summarization! Looking at the picture above, in the previous scenario,ccna 200-125 brain dump, we need to use 3 fine routes, but here we can achieve the same effect by using only one route. This route is the summary route of the three detailed routes in the previous scenario . A direct benefit of this configuration is that the router's routing table entries are greatly reduced. This mode of operation is called route summarization. Route summarization is a very important network design idea. Usually in a large and medium-sized network design, network and routing optimisation must be considered at all times. Route summarization is a time we need to shut down.
