tie. When B accesses the IPv6 network, the IPv6 address can be taken from the pool . In addition, in order to allow V4 network access V6 network has goals, but also made a static mapping, the 2001: 1 :: 1 mapped to 202.101.100.111 , so, B will be able to use 202.101.100.111 This IP to access IPv6 hosts A . Maximum route entry Image - 6to4 automatic tunnel configuration Unassigned End deny any Image R5 release B segment RIP routing,ccna vce dumps 2017, R2 and R3 can learn, at the moment we are in R2 and R3 are on to OSPF to inject RIP routing, assuming that R2 injected first, then the B route will be R1 update to R3 , R3 this When you learn B routing from both RIP and OSPF , then it will: The behavior of the router is hop-by-hop. Each router along the path to the destination network must have a route to the destination. Wherein R3 is as follows: Prefix Set ip next-hop Use show ipv6 neighbors to view neighbor entries. Route-map OSPF3to2 permit 20 match tag 20 Ip cef This flag is also related to stateful autoconfiguration. When it is not set (by default), nodes should not use stateful autoconfiguration mechanisms to configure parameters other than IPv6 addresses. Route-map test permit 10 match ip address 1 On R1 , only the summary route 32.0/21 is filtered, and all the detailed routes are released. If a standard ACL is used to match the route, how to write it? Image Next hop 5 : local site range; The IP configuration is as above. The R2 interface is configured with two IP addresses, and both have announced that the entire network runs RIP . 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. Neighbor: interface-id 4, link-local address FE80::FFFF:FE10:2 Neighbor priority is 1, State is FULL, 6 state changes Ipv6 enable Interface FastEthernet0/0 ipv6 enable RIPng Bgp router-id 2.2.2.2 OSPF and BGP Tunnel source serial 0/0 tunnel destination 10.1.23.3 When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 Neighbor 2001::1 update-source Loopback0 Interface FastEthernet1/0 The Response packet contains a maximum of 25 routing entries. OSPF redistributes routes to RIP : R3 configuration is as follows X Tunnel adapter isatap.{0DB7233C-89B7-49DB-A8C0-D1AA005F4E6A}: Gateway of last resort is 172.16.12.1 to network 192.168.1.0 Fa0/0 Information, so that ISP1 is hanging, so the data of the PC accessing the 100 network is switched to ISP2 , and the network is constantly 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. As the example above, it can be further abbreviated as: 2001 : a8 : 207 :: 8207 Nexthop ::FFFF:4.4.4.4 Ivv6 nat v4v6 pool v4v6-pool 2001:2:: 2001:2::FFFF:FFFF prefix-length 96 ipv6 nat v4v6 source list 1 pool v4v6-pool Straight connector Tunnel mode ipv6ip The 64btis interface identifier generated by the ISATAP host and the ISATAP router can be further used to construct the tunnel interface. When the packet enters the router, the router strips the Layer 2 information and then looks up the destination IP address in the CEF table for forwarding. The result of the forwarding decision will point to a neighboring entry in the adjacency list, in which the second layer of character letters that need to be rewritten can be found. Router ospf 1 DC Ipv6 address 2001::FFFF/64 no ipv6 nd suppress-ra 10.1.12.2 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. Image None Router bgp 300 Packets Show ipv6 neighbor ! Interface Tunnel1 In an IP network, Routing is a very, very basic concept. The basic function of the network is to make two in the network Metric R3 Via FE80::FFFF:FE10:5, Serial0/0 OI 2001:1:2::1/128 [110/192] Net 49.0001.0000.0000.0002.00 The configuration of R4 is as follows: The configuration of R1 is as follows: UP Phenomenon analysis: This should be said that there is no difficulty. At this moment, R2 is a multicast source, and the multicast data is directly sent to R1 . Configure OSPF unicast updates: Router(config-router)# no adjacency-check Image R2(config)# access-list 1 deny 192.168.3.0 R2(config)# access-list 1 permit any R2(config)# router rip Ipv6 address 2023::3/64 ipv6 nd suppress-ra Scop is used to limit the range of multicast data streams sent over the network. Command 5 : local site range; FIG Ibid, 4.0 after hang, C sends message poisoning message, theoretically 4.0 routing is C advertised to B , the principle of the horizontal division, B is not the C advertised 4.0 information, but with a level of toxicity reversal split broke this principle, B periodically to C sends 4.0 poison reverse messages to let C know, his neighbors knew a 4.0 hang message and waiting eagerly 4.0 resurrected place full of blood, another benefit of doing so is avoid loops, at least C is not from B to go visit 4.0 a.
