At this time, Win7 will automatically generate an ISATAP tunnel virtual interface: Image Neighbor FE80::CE02:8FF:FED8:0 activate 200-299 ; P has a label space of 300-399 ; PE2 has a 400-499 .

The result of the forwarding decision will point to a neighboring entry in the adjacency list,index of ccna dumps, in which the second layer of character letters that need to be rewritten can be found. Routing Protocols Neighbor 2023::3 activate Image Interface FastEthernet1/0 After the command is configured, the neighbor R2 receives the prefix and displays the following: R2#sh ipv int f 0/0 Enhanced Interior Gateway Routing Protocol (EIGRP) Open Shortest Path First (OSPF) 1/256 Access-list 1 permit 1.1.1.0 The transition mechanism of V4 to V6 discussed above is basically the case where V4 and V6 coexist. So if there is a need for mutual access to the V4 single protocol and the V6 single protocol network? ! IPv6 Address(es): FE80::FFFF:FE10:1 Origin IGP, metric 0, localpref 100, valid, internal, best Extended Community: RT: 234: 4 Timers IPv6 is enabled, link-local address is FE80::CE00:DFF:FE48:0 Global unicast address(es): Ipv6 address 2001:12::1/64 Route summary issues to be aware of Notice the Flag field, technical background Local site address (Site-local address) Image Let's look at the above scenario, focusing on the egress router. This egress router is a three-layer link with the Layer 3 switch. Therefore, you need to configure the backhaul route to the intranet, which is the red font part in the above picture. In this scenario, There are only three network segments on the intranet, so three static routes are configured, but what if there are 100 network segments? Do you want to have 100 routes? As a result, the routing table becomes very large and bloated, which is very inconvenient to maintain and manage. More importantly, this undoubtedly wastes resources of the device. Therefore, from the perspective of network optimization, no matter what kind of network model, we need to keep an eye on the number of routing entries in the router routing table in the network, whether it is sufficient for optimization, and whether there is room for optimization.
