202.101.100.2 . Therefore R2 receive this IPv6 time packets, 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. Image BGP router identifier 2.2.2.2, local AS number 12 BGP table version is 1, main routing table version 1 Interface Serial0/0 ipv6 enable 2 : link local range; eg FF02::1 indicates all nodes on the link; FF02::9 : indicates all RIP routers on the link At another point, R2 will take 10.0.0.0 , 11.0.0.0 (the network segment where the secondary address is located), and 1.0.0.0 and 3.3.3.0 from their own loopback. // new prefix Ipv6 router ospf 1 router-id 1.1.1.1 Image Metric 0, originator 0.0.0.0, path 300, community , extended community Configuration Example 3 (at a single routing protocols -OSPF ) Identify the type of message: That's what I mean 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. Ipv6 nd prefix 2012::/64 890000 720000 no-autoconfig Interface Serial0/0 ipv6 enable * 0x0000000B Image Ipv6 ospf 100 area 0 RIP also supports tags , but it must be version 2 . X Image For R2 , it is now in its own process 1 , while learning the route of this OE2 from R1 and R3 , how will it choose? Review Address-family ipv6 Image The A record in IPv4 is used to map the host name to a V4 address, and the AAAA resource record maps the host name to an IPv6 address. We can do a test: IP routing table ( IP Routing the Table ) ! Neighbor request ( NS ) Ip address 10.1.23.2 255.255.255.0 The AD value of 11.11.11.0/24 is adjusted to be larger than OSPF , for example 130 . So the configuration is as follows: In the figure above, we started the re-release action on R2 . We "inject" the OSPF route into the RIP process, so that or Stateless autoconfiguration The configured static network path is redistributed into OSPF . In this way, when the intranet user needs to access the Netcom resources, because of the details of the network access, go to OR1 . To access other resources, take the default route to OR2 . Router(config) router rip Image IGRP --- 202.101.100.2 0200 – 03FF 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. On the CISCO IOS router, configure the mapping of a host name to an IPv6 address as follows: The summary of the route is actually done by the operation of the subnet mask. For the following example: The following are the addresses and ports that DHCPv6 might use: Image Based on packet load balancing, all packets are rounded on the outgoing link. If you want to use message-based CEF load balancing, you need to configure this command on all outbound interfaces. The buddy experiment has verified that it can indeed be per-packet load balancing. Next, let's take a look at several exchange methods. Some of the contents of this section are excerpted from the network, thanks to the original author's sharing. Image Show vrf ipv6 detail view vrf details Exit-address-family ! By default, the stateless autoconfiguration announcement has a prefix length of 64 bits. The node receives the IPv6 prefix and appends its EUI-64 address to the 64 -bit prefix to form a 128 -bit IPv6 address. Enhanced Interior Gateway Routing Protocol (EIGRP) ISO IS-IS Neighbor FE80::CE02:8FF:FED8:0 update-source FastEthernet1/0 We finally do another test, that is, the ISATAP host pings 2008: 8888::1 . Requested node multicast address corresponding to each unicast and anycast address used Network 10.1.34.4 0.0.0.0 area 0 R2 re-released the incoming A network segment route and then got up? Then R3 will ignore the route from R1 update. For R3 , go to Network 10.1.34.3 0.0.0.0 area 0 No bgp default ipv4-unicast neighbor 2.2.2.2 remote-as 234 RIPV1 operational behavior In the process of double-point bidirectional routing re-release, many problems may occur, such as sub-optimal paths, potential routing loops, etc. This chapter will discuss this model and existing problems in depth. In the IPv6 specification, the aggregatable global unicast or local site address is not recommended as the next hop address. If you do this,ccna valid dumps 2019, the ICMPv6 redirect message will not work. Therefore, using the Linklocal address as the next hop may be more recommended in some cases. After all, the linklocal address is stable and long-lasting. When configuring the linklocal address as the next hop IP , you must associate the corresponding interface on the router. E.
