Ipv6 address 2001:0001::FFFF/64 Interface tunnel 0 Link-layer Addr 1/32 Difficult analysis test: There are 1.1.1.0 , 2.2.2.0 routes on R1 . 6PE : 6PE technology relies on BGP , BGP 's Peer is the need to manually specify,9tut ccna dumps download, it can be regarded as a semi-automatic tunneling technology. In an IP network, Routing is a very, very basic concept. The basic function of the network is to make two in the network UDP Ipv6 address test ::/64 eui-64 !! Use the obtained prefix ( test ), plus the EUI64 of this interface , to form the interface global ipv6 address Hosts should use DHCP for non-address config 90 Single match includes a plurality of conditional statements, logical or operation; multiple match when the statement, using the logic and operation. After completing the configuration, R2 show ip route Used by IPv6 nodes to send messages to themselves. *Mar 1 17:40:49.495: BGP(0): FE80::CE02:8FF:FED8:0 rcv UPDATE w/ attr: nexthop 254.128.0.0, origin i, Policy-based routing is more powerful and flexible than traditional routing. It allows network managers to select forwarding paths based on destination addresses and packet types, packet sizes, applications, or IP source addresses. The following is an example of an NA message: On the CISCO IOS router, configure the mapping of a host name to an IPv6 address as follows: PC can take the initiative to send RS to trigger router sends RA , without waiting for RA periodically sent before closing time to the RA . Basic When both the primary and secondary addresses exist, RIP will use both the primary and secondary addresses as the source to send routing updates. So R1 and R3 will learn the routing update of 2.2.2.0 . But R3 ca n't learn 1.1.1.0 , on the one hand, because R1 sends updates to R3 and is ignored by R3. The default keyword has a lower priority than the detail route. Use " ipv6 neighbor ipv6 address interface number mac address" to add a static entry to the neighbor discovery table, for example: CA004FEC0008CA014FEC00080800 So when R1 sends a big packet to R4 , there will be no problem. This is fragmented directly at the source of R1 . Of course, we can continue to experiment, set the IPv6 MTU to 1300 bytes on the Fa1/0 interface of R3 , and then continue R1 to ping the big packet to R4 , and finally the cache entry on R1 . OUT direction Ip route 0.0.0.0 0.0.0.0 10.1.12.2 Netsh interface ipv6 show neighbors Fast switching means that all packets destined for the specified destination are sent out from the same interface , so the exchange time and processor usage are greatly reduced. When packets destined for different hosts in the same network enter the router and there is also an optional route , the router will send the packet to the destination on the other path. So the router can do its best based on the balanced load of the target network.
