[Two times of prefix] From now on, when the ISATAP host needs to access IPv6 resources, the IPv6 data packet is encapsulated in the IPv4 tunnel,ccna dumps 2018 pdf, that is, the IPv4 header of the ISATAP tunnel is set , and then transmitted to the ISATAP router, which is then decapsulated by the ISATAP router. Help forward IPv6 data.

Enable ipv6 DHCP on the interface and call the pool 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.
