RFC 2373 does not define all 112 bits as a group identifier. Instead, it is recommended to use only the lowest 32 -bit group ID of the 112 bits and set the remaining 80 bits to 0 . 0000 0001 xxxx xxxx First B goes to ping 202.101.100.100 , the data packet is as shown. 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. The 64btis interface identifier generated by the ISATAP host and the ISATAP router can be further used to construct the tunnel interface. 4 NAT-PT#show ipv nat translations 2001:45::/64 FF01::1 node local range all node multicast address Router(config-router)# router-id xxxx In the Probe state, every unicast NS is sent every RetransTime ( r default 1S ) , and MAX_Unicast_Solicit is sent before waiting for RetransTimer . At infinite Stateless autoconfiguration R2 's F0/0 port is configured with proxy ARP , 3.3.3.0 network R2 itself is reachable, so R2 will respond to this ARP request with its own F0/0 port MAC . In fact, this is an ARP spoofing behavior: ) Mpls ldp router-id Loopback0 mpls label range 200 299 !! Restart after installation, default to open stateless automatic access address Mixed automatic configuration experiment ATT/P/OL About PBR Image Overview of tunneling mechanism Ipv6 unicast-routing ! DHCP PD Therefore, when CE1 accesses 2001:5555::5 from the source 2001:1111::1 , the data level is like this: Generally, it is 60-240 seconds longer than the invalid timer . If this time also expires, the routing entry is completely deleted. Cisco default 60s (note than invalidtimer multi- 60s ), RFC default 120s On R1 , only the summary route 32.0/21 is filtered, and all the detailed routes are released. If a standard ACL is used to match the route, how to write it? Address-family ipv6 neighbor 2001::1 activate R1(config-router)#distribute-list 1 in ? // All interfaces The configuration of R4 is as follows: Image Transition from the old routing protocol to the new routing protocol Therefore , the fragmentation of IPv6 is not performed on the intermediate router. When the path MTU is smaller than the packet to be transmitted, the source node itself fragments the packet. Image Local RFC1723 defines several compatibility switches Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP U - Per-user Static route Ipv6 address 2001:0001::FFFF/64 Anycast address has no special address space,cisco ccna practice exam, and uses a unicast address space. An IPv6 address is assigned to multiple interfaces, only for routers, and packets destined for anycast address are routed to the nearest one assigned to anycast address (determined by the routing protocol). Suitable for communication in One-to-One-of-Many ( one of a pair ) . The receiver only needs to be one of a set of interfaces. For example, if the mobile user accesses the Internet, it needs to access the nearest receiving station from the user due to the geographical location, so that the mobile user can not be too geographically too much. limits. Anycast address can only be used as the destination IP and cannot be used as a source.
