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. 4 Authentication Header the Authentication Header (Protocol 51 ) Switched Environmental description !! Connect the interface of CE2 The thing we have to do is very simple. These subnets are continuous. It is enough to pick out the first two or three network numbers to calculate: A specified 32bits of Router-ID Ip sla monitor schedule 1 life forever start-time now Set as-path set community Image Whether ICMPv6 code is 0 !! Interface activates IS-IS Image The dual-stack host on the IPv4 network first uses HTTP to access the tunnel server through IPv4 . The end user fills in the web page and obtains the IPv4 and IPv6 addresses from the tunnel server. Image compatibility ! Image R1 , the subsequent packets should not exceed 1400 bytes. The capture of this process is as follows: Ip route 172.16.1.32 255.255.255.224 192.168.23.3 Ip prefix-list ABC seq 5 permit 172.0.0.0/8 ge 24 The configuration of R1 is as follows: R2 , R3 establish IPv6 the EBGP neighbor relationship, R3 re-direct routes,ccna braindumps 2018, making the R1 , R2 can learn to ! Match interface s 0/0 :: route ipv6 / 0 0 tunnel !! ipv6 routing, front to IPv6 network traffic all thrown into the tunnel IPv6 reachability: This TLV defines such things as IPv6 routing prefixes, metrics, and some option bits. Assigned to IPv6 reachability Then you can use the route-map tool, that is, we can associate a route-map with the re-release , to implement the function I just mentioned. Configure OSPF unicast updates: 133 Image Interface FastEthernet1/0 Interface FastEthernet0/0 Distance 100 192.168.12.1 0.0.0.0 1 *>i2001:5555::5/128 Use " ipv6 neighbor ipv6 address interface number mac address" to add a static entry to the neighbor discovery table, for example: After getting the 6to4 IPv6 address space, the address space is 16+32=48bits , which is /48 , so the space is very large, you can further divide the subnet. This IPv6 address space will be used for the intranet. . Route summary So if we use a solution that re-releases static summary routes: 3 : MD5 verification. We focus on the 2001:5555::5/128 route, the next hop is a strange address, but from the last 32bits of this address is 4.4.4.4 it is not difficult to see who passed this route to me, in addition, The out label of the prefix is 403 , and this 403 is exactly what PE2 passed to me. In other words, PE2 as 2001: 5555 :: 5/128 This IPv6 prefix assigned 403 labels, and pass this map to the PE1 , the label is actually MP-BGP generated. Then when PE1 has data to go to 2001:5555::5 is it directly labeled 403 ? Of course not, because the label 403 for MPLS Backbone in the P routers, do not understand, therefore, we also need an outer label, the label by the LDPGenerated so that our packets can be transmitted within the MPLS Backbone .
