64bits interface identifier address, constitutes 128bits of IPv6 global unicast address, and it will generate a default route to the ISATAP Neighbor 2023::3 activate Ipv6 nat Next hop ! Image Via FE80::FFFF:FE10:2,200 125 ccna dumps free download, Serial0/0 OI 2001:34::/64 [110/192] Image Management distance ( Administrative Distance , referred to as the AD ) Also pay attention to the sending conditions of ICMP redirects here . Also note, R3 this default route on if configured to associate an outgoing interface, then it can not be observed phenomena redirection, as to the reason, you know, proxy ARP thing. Image ! 850 Image The arrival ISATAP the loopback of IPv6 packets, on a quilt ISATAP of IPv4 tunnel header, and then passed ISATAP Application prefix list 2001:1111::1/128 The first 8 bits of the route must be exactly matched with the first 8 bits of 172.0.0.0 . The other bits do not care, and the mask length must be greater than 24. Note that here ! The configuration of R3 is as follows: 32 bits Then just republish this static summary route into OSPF . In this way , the routers in OSPF can reach through this summary route. X ! !! Let R1 generate a packet with a message size of 1500 and send it to R4. With object tracking, PBR can be more flexible, and can make decisions based on ICMP , HTTP , the presence or absence of a route in the routing table, and the up/down of the interface . Neighbor FE80::CE01:8FF:FED8:10 update-source FastEthernet0/0 ! Of course, if a PC is initialized, it can also actively send an RS request about the prefix information. Mechanism involved Binary prefix (high bits ) Next, we R3 up of ping 2222 :: 2 , this action will cause the R3 transmits an ICMPv6 packet, source 2000: 123 :: 3 , the purpose of 2222 :: 2 , the packet will be sent to R1 , when R1 After receiving, he found that the packet will be forwarded from the interface that received the packet, and the next hop IP is on the same network segment as the interface, proving that the next hop is better than itself (distance from the destination) closer).
