Experimental configuration: Length, or mask length. When paired with the above ACL , some students will even write Image Access-list 1 permit 192.168.1.0 Router# Show ipv6 route 16 bits Experimental configuration No auto-summary no synchronization exit-address-family Image Or if the unrequested NA of B is received in the reachable state , and the link layer address is different, immediately ->stale The router queries through recursion, the next hop 2002: CA65:1703::FFFF should be thrown to tunnel0 , and tunnel0 is a 6to4 tunnel, so the 2002:CA65:1703::FFFF is translated into the corresponding V4 address, which is 202.101.23.3 // new prefix When ISP1 is down, and the GW does not detect it (that is , the interface of GW connected to ISP1 is not DOWN ), the traffic of PC access 100 is still thrown to ISP1 , which is disconnected. X.acme.com Use the Linklocal address as the source address of the protocol packet and send a RIPng message to the neighboring RIPng router. Use FF02::9 as RIPng This is a simple method of data offloading and path redundancy using the longest matching principle. Prefix-list bibliography In any IS-IS network,200-125 ccna dumps 2018, the L2 router responsible for inter-area routing must be contiguous. Similarly, for IPv4 single protocol environments, IPv6 single protocol environments, or IPv4-IPv6 environments, L2 routers must be contiguous. Otherwise a routing black hole will be generated. 100x xxxx xxxx xxxx Image R2 ignores R1 update sent over, because the "active examination", from R1 sent from the RIP updates and R2 of S0 / 0 Kou not in the same subnet, so R2 ignored R1 incoming routing updates. At this time, just validate-update-source under the RIP process of R2 . Mixed automatic configuration experiment IGRP ! Prefix announcement Interface Serial0/0 ipv6 enable Transition mechanism from IPv6 single protocol network to IPv4 single protocol network The configuration of R2 is as follows: Modified OSPF the AD value Dynamic routing protocol port number or protocol number Route-map test permit/deny 10 2000 – 3FFF 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.
