We can use the ip route-cache command , is enabled on the interface fast switching show ip cache to check the fast switching -related information . Image 6PE and 6VPE Ipv6 nat v6v4 pool v6v4-pool 202.101.100.10 202.101.100.20 prefix-length 24 Image Invalidation timer Ip address 10.1.12.1 255.255.255.0 Network 10.1.34.4 0.0.0.0 area 0 R3 sets the tag when injecting the route. Interface FastEthernet0/0 ipv6 enable The dual-stack host uses HTTP to access the tunneling proxy through IPv4 . This dual-stack host may be an end user that fills in a web page. Redistribute routes to the protocol 6PE : 6PE technology relies on BGP , BGP 's Peer is the need to manually specify, it can be regarded as a semi-automatic tunneling technology. Image IPX -> moving to Unassigned TCP/IP volume one Route-map OSPF3to2 permit 20 match tag 20 This comprehensive thinking question helps you sort through several solutions: Image Image Distribute-list 1 out The 64bits interface ID , and from ISATAP get the router to IPv6 global unicast address prefix 2001: 1111 :: before 64bits , constitute a PC 's IPv6 global unicast address: 2001: 1111 :: 200: 5EFE: 1.1.1.1 . RIP is re-released into OSPF Link-layer Addr Whether to support on-demand circuits Image No bgp default ipv4-unicast bgp log-neighbor-changes Match ip address 1 Eliminate routing loops by horizontal splitting RIP and IGRP the passive-interface does not send routing updates, but to accept routing updates Port number 520 Ipv6 nat v6v4 source 2001:1::1 202.101.100.111 If multiple next hop IPs are defined , when the local outbound interface associated with the first next hop is DOWN , it automatically switches to the next next-hop . Prefix list configuration Net 49.0001.0000.0000.0001.00 ! Wherein R3 is as follows: When the router is adjacent to the host,ccna security dumps 2019 pdf, they learn in some way. Network 2.2.2.2 0.0.0.0 area 0 Then start configuring BGP4+ : FF02::1:2 = ALL DHCP Agents ( servers or relays, link-local scope ) FF05::1:3 = ALL DHCP servers ( Site-local scope ) ! Do not send full router address in prefix advert Router(config-router)# no adjacency-check The A record in IPv4 is used to map the host name to a V4 address, and the AAAA resource record maps the host name to an IPv6 address. We can do a test: The IPv6 data of the 6to4 network can be forwarded by obtaining the corresponding public network IPv4 address from the destination IPv6 address . However, if the IPv6 island is not using the 6to4 address space, but a regular aggregatable global unicast address like 2001::/16 ? This requires the use of 6to4 relay. IPv6 has some special multicast addresses, which have special meanings. Ip sla monitor 1 Configure on R2 as follows: Access-list 1 deny 192.168.13.0 access-list 1 permit any IPv6 provides perfect support for Ipsec , so the upper layer protocol can save many security options, such as OSPFv3 cancels the authentication. Phenomenon analysis: This environment is not the same as before. First, the multicast data from R3 to Loopback0 port, then the First-hop router becomes R3 , instead of R2 a. Then R3 is the first hop router. After receivingthe multicast data sent by themulticast source (that is, its own LO0 ), R3 will trigger the Register process.The details of the register process are very familiar to everyone. winded, the end result is, R3 to R1 construct a SPF , from the reason that R3 Loopback0 port, sent to a multicast group FF04 :: 1 may be multicast data along the route R2 to R1 of SPF forward.
