ccnp 300-101 test

FastEthernet1/0 This is a simple method of data offloading and path redundancy using the longest matching principle. 100 200 i Regular updates, broadcast updates, routing table updates; according to rumors; distance vector routing protocols do not understand network topology 30 Experimental verification 82 Access-list 2 permit 172.16.20.0 route-map BGP2OSPF permit 10 As a result, all three switches exchange VTP packets to inform them that there is a VLAN for accessing users . For VLANs that do not have users locally , they will be automatically trimmed. Let's take a look: RSTP port status Manually modified. Ip mtu refers to the maximum value of the ip message. If R1 turns on auto-summary and network 1.1.1.0 mask 255.255.255.0 , it is still updated to R2 with details. | 802.1W Link-level data transmission: Receive data from the LLC sub-layer, attach the MAC address and control information, and send the data to the physical link; provide verification and other functions in this process. 2> Dynamic inbound soft reset Port 1 The message contains: Route-map test deny 10 match tag 1111 Router#show ip route Set local-preference set weight Weight After being injected into EIGRP , the tag is still carried. 200 i First ensure that R1 , R3 to 10.1.1.0 are routed, and test on R2 : Compare by default from top to bottom BGP can use the route tag in the OSPF packet to carry the AS_PATH information when it traverses OSPF . In fact, CISCO 's BGP automatically completes the process (note that only the AS_PATH attribute is automatically entered into the OSPF TAG field ). Switch(config)# ip default-gateway 192.168.255.254 !! Set the gateway for the access switch itself Both A and Root enter the Listening state on both ends of Link1 , and A will receive the BPDU sent by Root . 8 100 Weight 200 i Length : indicates the full length of the BGP packet, including the header. R2 configuration is as follows Route-map test permit 10 set community ? 2 The message contains: Set as-path tag FastEthernet1/0 10.1.25.2 Match community 30 Match ip address prefix-list 1 set weight 100 The smaller the RID of a BGP neighbor is, the higher the priority is. 11 No synchronization no auto-summary CISCO IOS 12.1 began to fully support dynamic soft reconfiguration of inbound routes. This soft reset method sends route-refresh messages directly to specific neighbors locally . 0 , regarded as infinity Then 1 , 2 are compared first, 2 is preferred (because 2 has a smaller RID ); then 2 is compared with 3 , 2 is external , so 2 is preferred Idle Gratuitous ARP It can be seen that since we configured the summary, the as-set keyword was used to make the summary route inherit the detailed partial path attribute. Therefore, the generated summary route still retains the aggregate attribute, but there is no atomic-agg attribute. Obviously this attribute It is no longer necessary in the case of the as-set keyword. DNS , WWW , and SMTP servers belong to the same subnet None Neighbor 1.1.1.1 remote-as 123 MAC address is 0007.b400.0102 (learnt) Owner ID is cc01.043c.0000 Router bgp asnumber Associate the static route of the next hop Received a Layer 2 frame. SW1(config-if)# ip address 10.1.1.253 255.255.255.0 100 2.2.2.0 Routing Although the next hop is directed to R1 , it does not use the outbound interface to create routing entries. From the experimental phenomenon, it is not matched by the match . Needless to say, 3.3.3.0 , the associated interface is s0/1 . Note the tool. Here is actually a summary of the deployment of static routes, of course, in addition to we can also route summary in the dynamic routing protocol, almost all dynamic routing protocols support route summarization. To do another test, PC1 privately modifies the IP address: Diameter refers to a diameter value, the default is 7 . This value is related to the STP timer. If the different diameter values ​​are configured,ccnp 300-101 test, the switch will automatically adjust the hello and max age timers. This command is usually configured on the root , so that the timer value is passed to other switches through bpdu . 2/1 BGP path/bestpath attribute entries using 248 bytes of memory 0 BGP route-map cache entries using 0 bytes of memory Set aging time Windows system), at the same time reply a Gratuitous ARP response to inform the peer that there is a duplicate IP address. Origin IGP, metric 0, localpref 100, valid, internal basic concept ? When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 10.1.23.2 Configuration example R1 , R2 , and R3 run RIP , and 1.1.1.0/24 on R1 is not directly announced. On R2 : OSPF TAG Overview Configuration case 1 command) only sends and receives v1 messages, v2 only sends and receives v2 messages by default . Do the following configuration on R2 and test it ( all tested in no ip classless and closed ip cef environment ): Show ip bgp summary Ip community-list standard del permit no-export ip community-list standard del permit 100:11 The smaller the RID of a BGP neighbor is, the higher the priority is. Start a TC while timer for the root port and all non-edge designated ports . The timer value is equal to 2 times the hello-time timer. !! vlan10 activates DHCP snooping Manual summary Note also that, because the R4 and R5 for the federal EBGP neighbor relationship, so there are also TTL is 1 problems, if they use the loopback interface to establish BGP relationship, it needs to use to neighbor 5.5.5.5 ebgp-multihop 3 command. Port-security configuration 3.3.3.3 Port Another way is to use ARP ACL : Because RIP appeared earlier, early routers used serial link interconnection (point-to-point links), so RIP triggered updates only supported on point-to-point links, for Frame-Relay and Ethernet. In the multi-access interface, RIP trigger update is not supported , but the Frame-Relay point -to- point sub-interface is considered by RIP to be a point-to-point link, and the trigger update can be enabled.
