Ipv6 enable You can use the show cef interface command to check which load balancing mode is used. This command gives the CEF information configured on this interface .

On R2 : UDP Abbreviation of IPv6 address Image Ipv6 address 2001:12::2/64 ipv6 rip RIPprocess enable OSPF Complete the basic interface IP configuration . Add the following configuration on R2 : Ipv6 nd prefix 2001:0001::/64 1 Y Image BGP table version is 1, local router ID is 1.1.1.1 001x xxxx xxxx xxxx S0 192.168.12.1/24 r1 Prefix readdressing None Protocol ID: 0x0800 Image Offset-list Acl number in/out offset value interface Source starts to send IPv6 packets using MTU=1400 , and the packet arrives at B. Between R1 , R2 and Layer 3 switches, it is assumed to be a static routing environment. So now, we hope that users under R3 will flow in the direction indicated by the red dotted arrow when accessing the production server, and will flow in the direction of the blue arrow when accessing the office server. --- 202.101.100.2 Ipv6 address 2001:0001::FFFF/64 Introduced in the route-map section of this document Tunnel0 [up/up] Network 3.3.3.0 mask 255.255.255.0 Image Image In an IPv6 over IP manual tunnel, the local tunnel and the address of the peer tunnel are configured on the two ends of the tunnel, that is, the two dual-stack routers. Therefore, the scalability is poor. To facilitate the deployment of manual tunnels on IPv4 networks, the IETF defines a tunneling proxy mechanism. Incomplete Reachable Stale Delay Image Address format: FF02:0:0:0:0:1:FFXX:XXXX , the specific correspondence is as follows: Address-family ipv6 Ip route 2.2.2.0 255.255.255.0 192.168.13.1 When ISP1 fails, GW senses through tracking , so the data is switched to ISP2.

In R1 , for example, arranged Tunnel 0 , assign an IPv6 address ( 6to4 address), this address is R1 is V4 external network address corresponding to the IPv6 6to4 address, i.e. 202.101.12.1 corresponding to Image Next hop Match ip address 2 Valid lifetime 25 preferred lifetime 10 !! The two times are decreasing. When the preferred lifetime first reaches 0 , the status changes to [DEP] . When the valid time becomes 0 , the address is erased. IPX -> moving to Unassigned Interface fast1/0 The configuration of PE2 is as follows: Gateway of last resort is 172.16.12.1 to network 192.168.1.0 ipv6 cef !! note that support IPv6 in PE on, IPv6 CEF must be opened Scanning messages on the intranet. The destination addresses of these packets are some unknown addresses that start with 192.168 , or even addresses that do not exist at all. The packet is sent to the gateway, which is the Layer 3 switch. Since the Layer 3 switch is configured with the default route,ccna dumps chapter wise, these packet destinations are matched by the default route and directed to the egress router, and the summary route is deployed on the egress router. Although the destination address of the packet does not exist in the internal network, it is an IP in the summary route , so it is forwarded back to the Layer 3 switch by the egress router. Then the Layer 3 switch forwards the packet according to the default route. Back to the router, this forms a loop of data.
