The command distribute-list out works only on the routes being redistributed by the Autonomous System Boundary Routers (ASBRs) into OSPF. It can be applied to external type 2 and external type 1 routes, but not to intra-area and interarea routes.

The number of addresses. The switch assigns MAC addresses in order When 10.4.0.0 is hanged , C will immediately send a route poisoning message ( 10.4.0.0 16 hops) and then advertise it; Address family identifier. When the value is 2 , it indicates the IP protocol.

Detailed rules Process Switching ( process swap ) If there is a tag , compare the VLAN tag of the frame with the PVID of the port . If the two are consistent, proceed to the next step; otherwise, discard the frame. The concept of traditional IP routing Let us review: When the router receives an IP packet, check the IP header of the packet, and take the destination IP of the packet to the routing table for comparison according to the longest matching principle. Finally, Forward the packet. Therefore, traditional IP routing can only be routed based on the purpose of the data. Port EtherChannel supports load balancing in the same port-channel link 200 i The configuration of R2 is as follows: None Origin codes: i - IGP, e - EGP, ? - incomplete Of course, on R3 , the same effect can be achieved with the distribution list in the in direction. Under normal circumstances, Rl is possible to ping through 3.3.3.3 , but if R2 f0 / 0 port agent arp turned off, then it ping nowhere outlet associated with the use of static routing, the router will route to the destination address that is the local chain Road, so send arp request for mac of 3.3.3.3 , and 100 i Ip route 172.16.3.0 255.255.255.0 172.16.12.3 Router bgp 345 Ip nat inside source route-map nat1 interface serial0/0 overload ip nat inside source route-map nat2 interface serial0/1 overload ip nat inside source route-map nat3 interface serial0/1 overload Port OSPF Port-security configuration // is equivalent to route-map not matching ( permit ) any entry, so all details are released BGP Configuration and implementation PVST+ Port Vlans allowed on trunk No default Lab 3 : The access layer switch is inserted into option82 , and the upstream core switch also turns on dhcp snooping. To control, the most simple and convenient. Le keyword is not written, then the default is greater than 24 less than 32 In CEF , there are two main types of load balancing, based on messages and based on purpose. Non-default (manually configured non-default) priority and cost unchanged Desirable actively attempts to make the link a trunk (default mode), sending DTP frames, and if the adjacency interface is trunk , desirable ,ccnp routing and switching todd lammle pdf, or AUTO , then the interface becomes a trunk . <1-4294967295> community number Ip route 10.1.1.0 255.255.255.0 10.1.254.1 / / View command: Show etherchannel 1 summary HOLDTIME CISCO defaults to 180s ( 3 times KEEPLIVE timer ), which is included in the open message. RR can modify the cluster-id The rules for BGP next-hop are as follows: Improve security, reduce the number of subnets, and increase IP utilization A sends a data frame to B requesting to establish a reliable connection-oriented connection. The route -map used by exist-map has at least the following two match statements: Redistribute static subnets After the data transfer is completed, A to B transmits a data frame to tell B releasable attachment, the communication ends. In general, a Layer 3 switch contains two types of ports: Layer 2 interface L2 and Layer 3 interface L3. Access-list 11 permit any route-map adv permit 10 match ip address 11 router bgp 12 LocPrf 5.5.5.5 ( metric 2 ) from 5.5.5.5 (5.5.5.5) Experimental phenomena: doing what Complete basic IP , IGP configuration, establish BGP connection On a specific interface, if no BPDUs are received for three consecutive cycles (or max-age timeout), the STP data on the interface will age rapidly. As a result, the BPDUs are somewhat similar to the keep-alive mechanism between switches . This fast aging mechanism helps to respond quickly to topology changes. Must be a zero field. Route-map Routing Policy R1 and R2 are private partners. Some special traffic may need to be protected. Therefore , the dedicated line between R1 and R2 is added. If you want to ensure the traffic between 1.1.1.0 and 2.2.2.0 is exchanged through the leased line (running) the RIP ) away, when the green DOWN , only to take the following multi-access network. Pay attention to the changes in our experimental environment. The community value carried in 12.12.12.0 is no-export , if we only want to match no-export Router bgp 345 Example of multiplication characters: The decision process of BGP is to use the local routing policy for the routes in ajd-RIBs-IN , and put the selected or modified routes into Loc-RIB and On R2 , in order to reach the network connected by R1 , R2 configures a tool that uses route summarization, referring to a summary route: 192.168.0.0/16 to R1 , although this does serve the purpose of network optimization, but this summary route Too "rough", it even includes the network segment on the R3 side, we call this behavior not accurate enough. Therefore, an ideal way is to use a "just right" summary route that includes these detailed routes, so that you can avoid the problem of insufficient aggregation.
