! Let's review the configuration of an IPv6 over IP manual tunnel (also called a configuration tunnel): Frame-relay map ipv6 FE80::5C10:8CFF:FEE0:FE89 102 broadcast Image CE1 and CE2 configuration Ipv6 address 2001::1/64 The configuration of R2 is as follows: Preferred lifetime ( of Preferred Lifetime ) Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd Ipv6 dhcp pool DHCP-pool Flags 4bits , 0000 : permanently assigned or well known ; 0001 : temporary Configure a NET address for this router , which is exactly the same as the IPv4 IS-IS concept. Ip route 0.0.0.0 0.0.0.0 202.101.12.2 L2 IP --- Ipv6 route 2222::/64 FastEthernet0/0 FE80::CE00:1AFF:FEE4:0 2001:1111:: 0000:5efe:0202.0202 /64 , so the prefix of IPv4 is 2001:1111::/64 ,ccna exam dumps pdf, this prefix will pass through the tunnel later. 2001:2::2 Interface FastEthernet0/0 no ip address technical background IPV6 and subnetting Ip address 192.168.10.254 255.255.255.0 The PMTU here refers to the one-way, the smallest of the data outbound MTU along the way . Configure an interface as a passive interface: Use " clear ipv6 neighbors " to clear the dynamic entries in the neighbor discovery table. After the completion, simply show it on R2 : 0 00:00:39 Image The public network address of the ipv4 applied by the R1 router is 202.101.12.1 ; the public network address of the R3 application is 202.101.23.3. 2 : link local range; eg FF02::1 indicates all nodes on the link; FF02::9 : indicates all RIP routers on the link Ip address 202.101.23.3 255.255.255.0 Matches the network number and prefix length in the route prefix to enhance the accuracy of the match. 835 Image After being injected into EIGRP , the tag is still carried. Complete MPLS Backbone of IGP and LDP Configuration Basic router configuration Image Router bgp 234 Common basic configuration Ipv6 router isis 2002 : IPv4 address : Subnet ID : The IPv4 address above the interface ID is the public network IPv4 address obtained by A or B. Note that this public network IP is very important. This public network IP change may lead to IPv6. Intranet IPv6 had to be readdressed. And, of course, this IPv4 address cannot use a private IPv4 address. Next Hop 2023::3 FastEthernet FastEthernet IEEE 802.3 Ipv nd prefix 2012::/64 no-advertise C 192.168.23.0/24 is directly connected, Serial0/1 Exit-address-family Fast switching may be called route-cache switching on some data. Ipv6 address 2001::FFFE/64 ipv6 nd other-config-flag ipv6 nd managed-config-flag Ip cef Image Note that the above is the default metric when re-publishing from other dynamic routing protocols into this routing protocol . If you republish a local direct connection or a static route, the situation changes, as follows: 1 Image Experimental phenomena: Image Interface fa1/0 Ipv6 enable Image Image Ipv6 router rip RIPprocess Note that if you use a virtual machine configuration, you must manually configure the linklocal address on the serial interface. Distribute-list Ipv6 address 2001:0001::FFFF/64 !! wherein 2.2.2.2 is R2 of Router-ID , attention since 100.1.1.0 in R3 of OSPF Must be zero Distance default 120 R1 , R2 , and R3 run RIP and only announce the direct link between the three. In R1 the ip default-network 172.16.0.0 1 : Request message, requesting all or part of the routing information from the neighbor; RIPng Run OSPFv3 as shown technical background As can be seen from the results of the packet capture, there are two layers of label . After the label is packaged into the P router , the top-level LDP label is popped up due to the PHP mechanism . Then the label packet is transmitted to PE2 , and PE2 pops up MP-BGP . The label is restored to the original IPv6 data and then forwarded to CE2 . RIP-1 only sends RIPv1 updates Basic configuration example Precautions Test phenomenon: can ping through Unassigned Router configuration: Next Hop RIPv1 Request message: You can request the entire routing table or request specific routing information. R 3.0.0.0/8 is possibly down , routing via 9.9.12.2, FastEthernet0/0 N The cost of the route. Describe whether the router is running MOSPF Last update from 192.168.34.3 on Serial0/1, 00:09:32 ago Routing Descriptor Blocks: !! If you do not configure this command, once the BGP neighbor is specified , the default ipv4 neighbor will The default keyword has a lower priority than the detail route. Since Source Address Use this command to view the router IPv6 routing table. Image Therefore, R1 will send an ICMPv6 Type=137 redirect message to R3 to inform R3 that it is going to destination 2222::3 , someone is better than me, and the key information contained in this ICMPv6 message is R2 is LINKLOCAL address . The message is as follows: Image Prefix re-addressing It is valid only when the router (or Layer 3 switch) disables the routing function ( no ip routing ); 8 bits R The difference between OSPF V2 and V3 : We mainly analyze: Now, let’s go to R1 again. FE80::CE02:8FF:FED8:0: martian next hop R2# In an IPv6 multicast address, there is a special multicast address called Solicited-node address (the requested node multicast address ) . The Solicited-node address is a special purpose address. Mainly used for duplicate address detection ( the DAD ) and alternative IPv4 in the ARP . The Solicited-node address consists of the prefix FF02::1:FF00:0 / 104 and the last 24 bits of the ipv6 unicast address .
