Improve QoS efficiency When the packet enters the router, the router strips the Layer 2 information and then looks up the destination IP address in the CEF table for forwarding. The result of the forwarding decision will point to a neighboring entry in the adjacency list, in which the second layer of character letters that need to be rewritten can be found. !! Note that this order must be matched because Ipv6 unicast-routing Image The 64bits interface ID , and FE80 :: / 10 constitute a PC 's Linklocal address: fe80 :: 200: 5EFE: 1.1.1.1 At the same time, PC will ISATAP router Linklocal address fe80 :: 5efe: 2.2.2.2 set as the default gateway [Experiment 7 ] There are subnet routes (no match); there are default routes Network Set metric-type sets the metric type of the target routing protocol RS requires the router to generate RA immediately Ipv6 dhcp server DHCP-pool Case: Double Exit NAT IPv4/IPv6 Application Ip route 172.16.1.0 255.255.255.0 192.168.12.1 The IPv4 and IPv6 address plans are as shown in the figure above. BGP table version is 5,ccna r&s dumps 2018, local router ID is 2.2.2.2 Use RS to request RA Tunnels ( the Tunnel ) Image Image RIP database Router bgp 234 View IPv6 routes O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2 ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2 The configuration of R1 is as follows: Holddown timer !! ipv4 routing, so that the route can access the tunnel destination , which is 10.1.23.3 Neighbor Notification ( NA ) Image Ip address 4.4.4.4 255.255.255.255 4 --- 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 Test Description: in R3 on of ping FF04 ::. 1 , the local interface Loopback0 Ipv6 access-list ipv6only-network permit 2001:1::/64 any 1.1.1.0 to 3.3.3.0 actually has two paths to go. If the RIP protocol is running in the network , in fact, for A , going to 3.3.3.0/24 can be shared by B and D load. However, in some cases, we hope to data is controlled, for example, we want to 1.1.1.0 Access 3.3.3.0 of the main traffic go B , when B hung up, then switch to the D on. So we simply in D deployment offset-List , in which the A notice 3.3.3.0 routing, increased 1 jump, then this route will be compared to B advertised to A route metric big a jump, A naturally preferably B .
