! Realize network interconnection Ip route 0.0.0.0 0.0.0.0 192.168.23.3 [Experiment 2 ] There are subnet routes (match); there are default routes, subnet routes !! Attention tunnel mode The router sends an icmpv6 message to an Ipv6 node , informing it that it is on the same local link in order to get a better router address to the destination tower. Distance default 120 Address-family ipv4 Interface FastEthernet1/0 FF01::2 node local range all router multicast address !! GW has no other configuration about routing Authentication Type 134 Image Address-family ipv6 Image Mechanism introduction 2001:1::1 twenty two Interface Serial0/0 The configuration of P is as follows: None None First, the Source sends an IPv6 packet to the target node with 1500 bytes as the MTU. ! Sending 1, 1500-byte ICMP Echos to 2034::4, timeout is 2 seconds: Image There are 1.1.1.0 , 2.2.2.0 routes on R1 . Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP U - Per-user Static route Unassigned Timers Ipv6 nd prefix 2012::/64 30 15 Access-list 1 permit 11.11.11.0 OSPF . In this way,ccna exam questions and answers 2014, for R4 , it goes to 192.168.1.0 , there is a sub-optimal path , that is, around the long way, take R2-R3-R3-R5 # 38.25.63.10 Experimental phenomena: Image IPv6 transition technology Prefix This flag is also related to stateful autoconfiguration. When it is not set (by default), nodes should not use stateful autoconfiguration mechanisms to configure parameters other than IPv6 addresses. Route-map cisco permit 20 match ip address 2 set metric 10 CISCO routers have two ways to find the global lookup of routes: classful ( Classful ) lookup mode and classless ( Classless ) lookup mode. Mechanism introduction IPv4- compatible address Alternative ARP Access-list 1 permit any route-map PBR permit 10 match ip address 1 The fragment reassembly function is performed by the source end itself, and the path MTU is discovered through the PMTU mechanism. Ipv6 access-list ipv6only-network permit 2001:1::/64 any ipv6 nat prefix 2001:2::/96 Interface FastEthernet0/0 Image Ip policy route-map PBR The Permit/deny keyword has a different role in different deployment scenarios. Before we talk about are two IPv6 islands of use is 6to4 of IPv6 address space. The 6to4 border router is sent to receive Complete the configuration of CE1 and CE2 . :: Image Image Ipv6 route 2002:CA65:1703::/48 Tunnel0 Hex MAC address mapping for IPv6 multicast addresses IS-IS Level-1 Link State Database: IP protocol number 89 bibliography Set ip next-hop 10.1.1.2 10.2.2.2 interface fast 1/0 The BGP4+ configuration of R3 is as follows: Metric !

Ipv6 unicast-routing ! Dynamic routing protocol port number or protocol number R1 and R2 are dual-stack routers. The configuration of R1 is as follows ( the configuration of interface IP is omitted ): Router bgp 300 Neighbor FE80::CE01:8FF:FED8:10 remote-as 12 Interface ID: After ISATAP is enabled on the host, an ISATAP virtual network card is generated. The virtual network card generates a 64- bit special interface identifier, which is similar to EUI-64 . However, the mechanism is different. It isreserved by 32 bitsreservedfor ISATAP .The 0200:5EFE is combined with the IPv4 address configuredon the host.As shown in the following figure, ifthe IPv4 addressconfigured by the ISATAP hostis 1.1.1.
