6000 – 7FFF Experimental verification In the Probe state, every unicast NS is sent every RetransTime ( r default 1S ) , and MAX_Unicast_Solicit is sent before waiting for RetransTimer . Image No passive-interface fast 0/24 Also pay attention to the sending conditions of ICMP redirects here . Also note, R3 this default route on if configured to associate an outgoing interface, then it can not be observed phenomena redirection, as to the reason, you know, proxy ARP thing. R2 , R3 establish IPv6 the EBGP neighbor relationship, R3 re-direct routes, making the R1 , R2 can learn to Bytes tag This technology is used less and is one of the first conversion mechanisms of the IETF . The automatic IPv4- compatible tunneling mechanism allows only IPv6 data between two dual-stack hosts to be automatically tunneled (without manual configuration) over the IPv4 network. This mechanism allows for isolated hosts and another on an IPv4 network Adjust DAD Route-target export 234:2 Ipv6 address 2001:34::3/64 The TAG value is set when the originating ASBR generates an external LSA . If the external LSA is re-advertised to other OSPF autonomous systems, the TAG value is carried by default. RIP update source problem Image So 6to4 tunnel is done automatically find and set up, without having to manually configure the tunnel 's Where do you want , compared to the tunnel configuration, scalability is higher. --- Ipv6 address 2001:0001::FFFF/64 6to4 relay Ip rip triggered Configure an interface as a passive interface: !! If you add the default keyword, it will add a default on the interface that gets the address. In this way, whether the method of re-publishing the static summary route or the method of distributing the list filtering route can ensure that the network is not interrupted in the event of a network failure, as follows: 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 . LSPID Image FastEthernet0/0 [up/up] There are some other messages, which are described below. Ipv6 router ospf 100 router-id 2.2.2.2 R2 will use the primary address and the secondary address for validate-update-source ,ccna collaboration dumps pdf, so R2 can learn 2.2.2.0 and 3.3.3.0 routes. Image If the above is replaced by EIGRP , the phenomenon is the same as RIP , R1 will declare 1.1.1.0 into EIGRP. Image ! About PBR 10.1.12.2 When the router is in the boot mode and the software is upgraded, the ip routing is also closed, so the command will be used when necessary. Image FastEthernet0/0 ICMPv6 messages used by the NDP mechanism : Route-map PBR permit 20 match ip address 2 Ip address 2.2.2.254 255.255.255.0 Routing Information Protocol (RIP) Fa0/0 Next header (the Next Header) : This field defines the immediately IPv6 extension header behind the first header ( if present ) type or protocol type of the upper layer protocol data unit. 4 Offset-list { access–list-number | name } {in|out} offset [ interface-type interface-number ] --- [Start process exchange] Network 10.1.23.2 0.0.0.0 area 0 Situation 2 FastEthernet0/0, Forward, 00:00:04/00:03:24 Adjust the parameters of the NDP message The allocated portion of the entire IPv6 space: Ip address 202.101.100.1 255.255.255.0 Ip address 202.101.23.3 255.255.255.0 Match ip address 1 set metric 20 In IPv6 , the determination of the link layer address of a node is done using a combination of NS , NA, and the multicast address of the requested node. This ratio IPv4 's ARP 2001:1::CE03:1AFF:FEC4:0, subnet is 2001:1::/64 [PRE] 204 1 : Request message, requesting all or part of the routing information from the neighbor; 2023::2, subnet is 2023::/64 Joined group address(es): F000 – F7FF Image Requested node multicast address Solicited-node 25 Tiao FastEthernet0/0 None 2023::3 After completing the configuration, R2 show ip route The node has two protocol stacks, IPv4 and IPv6. Image Destination Address (Route Prefix): This is the destination network number associated with the route entry. A complete route prefix consists of: network number + prefix length IPv6 Routing Table - 12 entries 1 Therefore, when CE1 accesses 2001:5555::5 from the source 2001:1111::1 , the data level is like this: Avoid routing loops with triggered updates Neighbor FE80::CE01:8FF:FED8:10 update-source FastEthernet0/0 When a host receives an RA router advertisement, it will look at the M bit in the RA . If the M bit is 1 , it starts looking for DHCP on the LAN . After the route-map is called, the matching action will be executed from the smallest sequence number. If the conditions in the sequence number are matched, the set command is executed . If the conditions do not match, the switch to the next sequence number is continued. Match the action. Ipv6 address 2001:23::2/64 Router ospf 1 Ipv6 ospf 100 area 0 Prefix list is much more controllable than access list, supports incremental modification, and is more flexible Phenomenon analysis: R3 directly generates multicast data. The source IP address of the multicast data is the interface IP address of R3 Fa0/0 , and the destination IP address is the multicast group address FF04::1 . These multicast data is sent directly to R2 . At this point, R2 is the First-hop router. Then when R2 received when the multicast data, because it is received in a multi-access network (in their Fa1 / 0 port), and their Fa1 / 0 port is free and not the LAN in the DR , since If it is not a DR , it has no right to initiate a register to the RP . Therefore, R2 simply creates an IPv6 group.
