ATT/P/OL Ip default-network 172.16.3.0 [Experiment 7 ] There are subnet routes (no match); there are default routes After getting the 6to4 IPv6 address space, the address space is 16+32=48bits , which is /48 , so the space is very large,ccna 1 braindumps, you can further divide the subnet. This IPv6 address space will be used for the intranet. . Difficult analysis Now, change the interface ipv6 MTU of the F1/0 port of R2 to 1400 bytes (the default interface IPv6 MTU in the above figure is 1500 bytes): 10.1.12.2 OSPF and RIP 202 Used to increase the route metrics learned through EIGRP or RIP when inbound or outbound . Exit-address-family None Image Image A default route will be published into the RIP and passed to other routers. For example, R1 , R2 , and R3 run RIP and open loopback on R1 . 2.2.2.0, but the update is 2.0.0.0 after the summary --- 202.101.100.2 Image Here , the "high-order 32bits reserved for ISATAP " in the 64-bit interface identifier is described on Wikipedia: " The link-local address is determined by concatenating fe80:0000:0000:0000: 0200:5efe: for global unique Host can send If there is a response, Reachable , if not, enter Empty , that is, delete the entry. Ipv nd prefix default ? Basic configuration example Link-layer Addr No frame-relay inverse-arp ipv6 enable As shown above, R1 , R2 , and R3 run RIP . In the initial situation, R2 will update its routing table to R1 , which assumes that there are three routes 1.0 , Image When R2 is configured with no validate-update-source , R2 will not verify the RIP update message source, so R2 will accept R1. Router-id 4.4.4.4 Image Ipv6 address 2001::FFFE/64 no ipv6 nd suppress-ra In a real network environment, we may encounter a situation where there are two or more routing protocols in a network environment, for example: Image Dynamic routing protocol port number or protocol number R1(config-router)#distribute-list 1 out ? The IPv6 prefix reserved for NAT-PT . Then use the ipv6 nat prefix 2001:2::/96 v4-mapped v4map command to associate this ACL . In this way, when A accesses B , you can directly use the 2001:2:: CA65:6402 address to access B on the V4 network . Note that the prefix 2001:2::/96 is the IPv6 prefix reserved for NAT-PT . The latter CA65:6402 will be translated into an IPv4 address, ie Run OSPFv3 as shown Neighbor discovery and adjacency formation mechanisms are the same Image X.acme.com Interface FastEthernet0/0 The distribution list is deployed in a link state routing protocol such as OSPF . If the out direction is to be used, it can only be used in such a situation.

And because there is no RIP route in the routing table , the natural RIP re-release to OSPF fails, and even worse, R4 about S 172.16.0.0/16 [1/0] via 172.16.3.0 S 172.16.3.0/24 [1/0] via 172.16.23.3 FC00 – FDFF 2 : Reponse message, send all or part of its routing information, in a Response message B removes the IPv4 header of the packet , obtains the original IPv6 data, and forwards it to PC2 . Image The data is two-way. When considering traffic, pay attention to the round trip of traffic. Authentication is identified by setting the address family ID field to all 1s ( 0xFFFF ).

Pass the RIP update with an unnumbered address ( invalid source ) Image This is a very typical scenario. GS_SW is an aggregation layer switch that runs OSPF with the core switch . The GS_SW needs to advertise the network segment corresponding to the VLAN to be hanged , so that the core switch can learn the relevant routes. Then, once GS_SW announces the network segment corresponding to these VLANs in the OSPF process , the corresponding SVI interface will flood the OSPF HELLO message to the VLAN , and these messages are actually redundant.
