100 Network 100 9.9.23.0 is directly connected, FastEthernet0/0 byte A frame whose type field is 0806 represents an ARP protocol frame. Ip dhcp relay information trust-all Store the result of the CRC cyclic redundancy check 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. Switch(config-if)# ip address 192.168.255.1 255.255.255.0 ? Network 10.1.25.0 0.0.0.255 area 0 BGP table version whenever the BGP table changes, this value is +1 Ip address 10.1.13.3 255.255.255.0 Configuration command 46 When we set the number of MAC addresses allowed on the interface to 1 and set a secure address for the interface, then this interface will only be for that MAC. Router bgp 345 Configure a static default route locally, such as ip route 0.0.0.0 0.0.0.0 null0 When both DSAP and SSAP take a specific value of 0xaa , the 802.3 frame becomes the ETHERNET_SNAP frame. 8 bits Router(config-router)# distance eigrp internal-distance external-distance The access layer switch uses a dual link to connect to two aggregation devices to form a Layer 2 environment with physical link redundancy, which solves the problem of single link failure. switchport trunk encapsulation dot1q switchport mode trunk If you reconfigure a secure trunk as an access port, port security converts all sticky and static addresses learned on the native VLAN to addresses learned on the access VLAN of the access port. Port security removes all addresses learned on VLANs other than the native VLAN. If you want to turn off ICMP redirects, you need to use no ip redirects on the interface . R5 sees the redundant path to the 100.0 network, the next hop is 3.3.3.3 , and finally R5 prefers R2 as going to 100.0 Switch(config)# vlan 10 Tunnel Tunnel interface ...... 192.168.8.0/24 200 i A sends the BPDU out of its designated port, and the BPDU is flooded to the network. Configuration command: In interface mode, you must configure the interfaces on both ends of the link. After the completion, you can show ip rip database to view the routing details. 16 bits It is recognized that the attributes must be followed to describe the sequence of AS numbers that must pass through the target network . The most important role is anti-ring. If the BGP speaker finds that its AS number appears in the AS_PATH of the received BGP route update , it indicates that there may be a routing loop, and the routing update is ignored. Another important role is that in the BGP routing, as the measurement of the AS hop count, of course,ccnp 300-115 book, the fewer ASs included in the AS_PATH , indicating closer to the destination.
