VTP operation A valid entry in the database matches these ARP packets. A distribution list is a tool used to control routing updates. It only filters routing information and cannot filter LSAs . Therefore: the distribution list is used in the distance vector routing protocol, and the route can be filtered normally in either in or out direction. But the work in the link state routing protocol is a bit problematic. Access-list 1 permit 10.1.1.0 Weight About the burst-size parameter: 3.3.3.3 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 Detailed rules Network Detect the reachability of the next hop, the default is off Ip summary-address rip xxxx yyyy // Note that this summary does not support CIDR supernet . Fa0/20 1-4094 Principle of ARP protocol Test purpose: VTP pruning 3.3 802.1D Instead of tearing down and rebuilding TCP or BGP connections, only the update operation is triggered to make the new routing policy take effect. Soft reset can be used for both inbound and outbound policies only due to outbound or inbound policies. 8.3.4 Questions 104 s> 172.16.10.0/24 / / There is a S entry in the routing table Route-map OSPF3to2 permit 20 match tag 20 Values ​​are " i ", which is better than "?" We still have to implement R4 access to 100.0.1.0 network to go R1 , access 100.0.2.0 network to go to R2 , this time we adjust MED , The summary of the route is actually done by the operation of the subnet mask. For the following example: May be provided for routing cost , cost-ID is equal to the time, preferably cost small. If the cost is equal, select the cost-ID is small. ? Bgp bestpath med confed No auto-summary RouterID : 172.16.13.1 *> 11.11.11.0/24 ! Set the timer of STP 100 i 201 10.1.23.2 Metric LocPrf Weight The configuration of R1 is as follows: Metric =0 BGP routing table entry for 172.16.0.0/16, version 3 If the aggregate-address does not contain any keywords, the details are also passed, and the summary route is also passed. / / Detailed release Conduct a three-layer forwarding decision. The CEF table maintains core information extracted from the routing table, which is used to perform forwarding decisions on received messages, including IP prefixes, recursive next hop addresses, and outbound interfaces. An important feature of the CEF table is its ability to make immediate decisions about recursive prefixes. R3 is added as follows: Port Security : Enabled Port And SW3 on the same case Option 82 sub-option 2 : Remote ID , which is generally the MAC of the access layer switch that inserts the option 82 information . Host 192.168.1.111 255.255.255.0 Router bgp 300 R3 and R5 both advertise the routes of the same network segment to R4 . If the first eight rules cannot be determined, if R4 is configured: Configure EIGRP unicast updates: No ip routing Unreliable based on broadcast By default, as long as DAI drops the message,ccnp tshoot portable command guide pdf, it will be logged Origin IGP, metric 0, localpref 100, valid, internal The non- root bridge receives the TCN on its designated port After this time has elapsed, the route entry will become 16 hops, marking the unreachable route possibly down . Gateway of last resort is not set Version Private-vlan community Vlan 102 Ip route 172.16.1.0 255.255.255.0 192.168.12.1 In order to verify this rule, we first maintain the basic BGP configuration. Introduce 100.0 by using network on R1 / / This is used to delete the no-export attribute, is a list of commands // in R3 is only 1.1.1.0 route, that distribute-list 1 out here this command, all externally injected into the Neighbor 4.4.4.4 update-source Loopback0 neighbor 10.1.25.2 remote-as 200 IP learner Define matching criteria Unsuppress-map R3 and R4 update the routes in AS1 and AS2 to R5 and R6 at the same time . If R5 is required to go to AS1 , take route R3 and go to AS2 . Interface loopback2 Dynamic routing protocol port number or protocol number 7 Set the interface to access mode R3 sets the tag when injecting the route. Note that the routes introduced outside the federation, the next-hop attribute will not change within the federation, even if it is passed between different member ASs , so R3 and R5 need to modify the next-hop attribute for R4 , set For your own update source IP , you already know how to do this? TCN BPDU Understand the invalid arp entry Rl , R2 formed between the EBGP neighbor relation (using respective LOOPBACK port) at the same time, Rl in the BGP process network 1.1.1.0 mask 255.255.255.0 incorporated 1.1.1.0 Network 0 , regarded as infinity 32768 R3 announces 192.168.1.0 , 2.0 , and sets the community attribute of 1.0 to no-adv. About PBR Local-as Certification Vlans allowed on trunk abbreviation OSPF redistributed directly connected interface default cost20 ; redistributed static route default cost20 ; using the default-metric can modify and redistribute static routes into other routing protocols OSPF default after the cost , but this command to redistribute directly connected interface. invalid. 100 Ip route 0.0.0.0 0.0.0.0 192.168.123.1 FastEthernet1/0 Configuration example 2 : as-path access-list with route-map Via 10.1.13.3, FastEthernet1/0, 0 dependencies The process of processing a VLAN frame by a trunk port is as follows: Ip address 192.168.100.254 255.255.255.0 IGRP We can R4 use the bgp always-compare-med command to force R4 compare routes MED The processing of the DHCP packet of option82 . BEGIN Neighbor 10.1.35.5 unsuppress-map unsupp Network Example 2 of ip community-list (logical relationship): Experimental verification ( EBGP equivalent load balancing) The Client does not know its own Client , so the RR itself can also become a client of others. SW1(config)# interface vlan 10 It can be activated in interface mode or in global mode, which is different. 10.1.23.2 Use route summarization! Looking at the picture above, in the previous scenario, we need to use 3 fine routes, but here we can achieve the same effect by using only one route. This route is the summary route of the three detailed routes in the previous scenario . A direct benefit of this configuration is that the router's routing table entries are greatly reduced. This mode of operation is called route summarization. Route summarization is a very important network design idea. Usually in a large and medium-sized network design, network and routing optimisation must be considered at all times. Route summarization is a time we need to shut down.
