new ccna

Pointer to the target: The pointer does not point to the router's direct connection to the destination network or to another router address in the directly connected network ,new ccna, or to the local interface of the link. A router that is closer to the target network is called a next hop router. FF02::1:FFF0:10 Ipv6 unicast-routing interface Serial0/0 encapsulation frame-relay 2) After the packet arrives at R2 , there is already a mapping in R2 local: 2001:1::1 maps to 202.101.100.100 Ip cef External route tag. RIP secondary address problem A tool used to control routing updates can only filter routing information and cannot filter LSAs . The following are the parameters used during and after the auto-configuration process: RFC2080 Image LSP Checksum Adjust the parameters of the prefix announcement Interface serial0/0 Authentication Header the Authentication Header (Protocol 51 ) Ipv6 router ospf 100 router-id 3.3.3.3 exit IPv6 address configuration method Route redistribution is directed. The routing information of the A routing domain is injected into the B routing domain. We need to configure it in the process of the B routing protocol. For example, to redistribute other routing protocols to RIP , then configure. As follows (republishing to other routing protocols is similar): *Mar The adjacency list in the CEF component is used for MAC or Layer 2 rewrite information. OSPFv3 uses the IPv6 Linklocal address to identify OSPFv3 neighbors. IP Address Ip route 0.0.0.0 0.0.0.0 192.168.23.3 Ipv6 nd prefix 2012::/64 890000 720000 no-autoconfig Ip cef or RIP-1 Only Preferred lifetime ( of Preferred Lifetime ) MP-BGP Slot Slot unit 0 VC -1 FF02::1 link local range all node multicast address FastEthernet0/0 Double-point bidirectional routing re-release R1(config-if)# ipv6 address 2001:0001::/64 eui-64 None Solicitation request and Router Advertisement notification message. The former is used to discover the router and causes the router to send the Router. LSP Checksum Image IPv6 packets are carried over IPv4 packets. 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 .
