However, we found that on R2 , we have been able to learn the IPv6 prefix passed by R3 ,ccna real exam questions, but the IPv4 prefix has never been received. On R2 , you can also see the following error: R 3.0.0.0/8 is possibly down , routing via 9.9.12.2, FastEthernet0/0 Interface fast0/0 Ipv6 enable Match ip address 1 set metric 20 Image Image !

Ip rip trigger Via FE80::FFFF:FE10:5, Serial0/0 OI 2001:1:2::1/128 [110/192] ALG and IPV4 single protocol network host B maintain an IPV4 session. ALG is responsible for session conversion between IPV4 and IPV6 . This ALG has dual stack support capabilities. For example, suppose ALG is a dual stack and can act as a server for SMTP ALG . Then A can be based on IPV6 of 2002: CA65: 0C01 :: 1/48 , R3 empathy. The next step is actually the trick of static routing. At this time, the intranet has data to go to 2001:0002::/16 Image None 2 : Reponse message, send all or part of its routing information, a Response Image Ipv6 dhcp server DHCP-pool !!

Untagged !! Re-emphasize the necessity of the next few orders In the Probe state, every unicast NS is sent every RetransTime ( r default 1S ) , and MAX_Unicast_Solicit is sent before waiting for RetransTimer . Network 2.2.2.2 0.0.0.0 area 0 Bgp router-id 2.2.2.2 Configuration example Router(config-rtr)# split-horizon Router(config)# ipv6 route destination IPv6 network / prefix length { outbound interface | next hop IP } F800 – FBFF [Experiment 7 ] There are subnet routes (no match); there are default routes The ISATAP router thus traverses the entire IPv4 network. Ipv6 enable ! The tunnel interface is used for ISATAP . In this case, the tunnel interface generates a 64-bit interface identifier based on the IPv4 address . This interface identifier matches the upper-level fe80:: to form the Linklocal address of the tunnel interface : fe80:: 0000:5efe:202:202 . In addition, you need to configure a global unicast IPv6 address for the ISATAP tunnel interface . You can configure it manually or by prefix +EUI64 . Here, EUI-64 is the special 64bits interface identifier described above .
