Ip route 0.0.0.0 0.0.0.0 192.168.12.1 Then, in order for R3 to dynamically learn the routing of production and office servers, it is now necessary to redistribute these two static routes into OSPF . Of course, there are tricks when re-publishing. The configuration of R3 is similar; R2 only needs to configure the interface IP ; PC1 and PC2 are each equipped with an IPv6 address, which means the gateway can be. Image For example , the configuration of R3 is as follows: Y The IPv4 and IPv6 address plans are as shown in the figure above. IPv6 basic experiment Note that the above is the default metric when re-publishing from other dynamic routing protocols into this routing protocol . If you republish a local direct connection or a static route, the situation changes,ccna exam cost, as follows: Prefix announcements are the initial mechanism for stateless autoconfiguration. Using RA ( ICMPv6 Type 134 ) and the multicast address of all nodes ( FF02::1 ), the router RA message is periodically sent to FF02::1 on the local link . test: Origin incomplete, metric 1, localpref 100, valid, internal, best mpls labels in/out nolabel/403 Image Internal 0 packets, 0 bytes Ipv6 address 2000:12::2/64 ipv6 ospf network point-to-point ipv6 ospf 1 area 0 Vrf definition cisco rd 1:1 Field name The IPv6 address used by the automatic IPv4 compatible tunneling mechanism is " IPv4- compatible IPv6 address". 202.101.100.2 CE1 's IPv6 prefix, and forms a VPNv6 prefix, which is advertised to its own MP-BGP neighbor PE2 . PE2 will correspond to the VPNv6 prefix. 1/128 Route-map defaults to permit , the default serial number is 10 , the serial number is not automatically incremented, and the serial number needs to be specified. Now we consider that when R1 originates an OSPF internal route, both R2 and R3 can learn this route. Then on R2 , the route is re-released from process 1 to process 2 , and finally R3 will learn the route from R4 . So for R3 , the dual OSPF process, Bgp router-id 3.3.3.3 Another CASE that associates the static route of the outgoing interface : Mpls ip Message name Image Interface Loopback0 The BGP4+ configuration of R2 is as follows: Ip address 10.1.23.3 255.255.255.0 So now, we add the following in the configuration of R2 : It can contain up to 25 routing entries. Ipv6 unicast-routing Cisco CEF is the most efficient three-layer protocol. CEF uses a hardware-based platform . It not only stores data in the system buffer, but also " prestores " the entire routing table, topology table , and all next hop addresses and MAC addresses , as long as the routing table, The entries in the topology table , regardless of whether there is a data request sent to its destination address , will be pre-read in advance , pre-set the cache . Thus , when there is a new data request to send , the CPU is not required to query the destination interface , destination MAC Address and other information , but read directly from the cache , so the forwarding speed is greatly improved .
