Each sequence number statement in the Route-map is equivalent to each row in the access control list. Top-down processing in the order of the serial number, once the matching sequence is found, it will not continue to search. ::FFFF: 4.4.4.4 Ipv6 nat After R3 receives this ICMPv6 redirect message, subsequent packets will be sent directly to R2 , so there is no need to bypass R1 . Default 30s , RIP update cycle Image Tunnel source fastEthernet 0/0 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 OSPF and IBGP route re-release Match ip address 1 Ip address 2.2.2.2 255.255.255.255 Ipv6 unicast-routing Of course it includes information such as object MAC address , contents of the destination interface . In this case we need only one data stream (Flow) in the first packet do process In R2 opened on loopback interfaces 2.2.2.0/24 , R2 both redistributed RIP into OSPF ,ccna security syllabus, they redistribute directly connected into OSPF The configuration of PE1 is as follows: FastEthernet0/0 Image R1 Network 192.168.254.0 0.0.0.255 area 1 Tunnel source serial 0/0 tunnel destination 10.1.23.3 PC (using router emulation) uses stateless auto get address: ipv6 address autoconfig default The primary purpose of PMTUD is to discover the MTU on the path and avoid fragmentation as the packet is forwarded from the source to the destination. Dependent on the PMTUD source node can communicate with the destination node using the largest PMTU found , which can avoid the packet being fragmented by the midway router during the process of transmitting from the source to the destination, resulting in performance degradation.
