ccnp switch chapter 3 exam answers

LocPrf R3 's loopback interface IP has been declared into OSPF , and R4 learns loopback routing through OSPF . Therefore, the BGP table for R4 is as follows: R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. Generally done at the AS boundary, tell yourself the local-pref value from within AS . Match ip address prefix-list In R1 to the 1.1.1.0 and 1.1.2.0 do a summary, as 1.0.0.0/8 , if coupled summary-only keyword, two details will be suppressed by inhibiting a bar if you want to cancel the details of a neighbor, Such as 1.1.1.0 , then Dialer Dialer interface Vlan 100 Identify the type of message: Not advertised to any peer Too many neighbors, managing these IBGP adjacencies will be a challenge and burden the device. Fortunately, we have two measures to help solve the problem, 1 is the route reflector 2 is federated. The Length field defines the number of bytes that the Data field contains. ! Fast switching may be called route-cache switching on some data. R1#show ip cef 2.2.2.2 internal Pay attention to the changes in our experimental environment. The community value carried in 12.12.12.0 is no-export ,ccnp switch chapter 3 exam answers, if we only want to match no-export R3 is added as follows: Ip prefix-list 1 permit 100.0.1.0/24 ip prefix-list 2 permit 100.0.2.0/24 route-map LP permit 10 The new routing table is typically sent to neighboring routers on a regular basis, and the triggered update is sent immediately in response to changes in the routing table. Next we SW1 of the Fa0 / 20 interface, do switchport allowed vlan the Remove Trunk 10 , the vlan10 traffic pruned, this time the PC between can not ping pass, go R1 speaking about: Interface vlan 20 * i Activates self-recovery of the err-disable interface due to arp-inspection violations . The configuration of SW1 is as follows: 5.5.5.5 Set ip next-hop 22.2.2.2 None IP nodes can communicate, and communication is actually the process of data interaction. Data interaction requires network devices to help us transfer data between two communication nodes. When the router (or other Layer 3 device) receives an IP packet, the router will find out the purpose of the IP packet in the Layer 3 header. Other configuration Interface loopback0 B performs the corresponding checksum confirmation according to the type of the connection, and after confirming by these checksums, it is sent to the upper layer. COST community : Accepts Inferior BPDUs BGP table on R7 : The TCP connection was not successfully established and the TCP connection was tried repeatedly . Knowledge review (interface) ip load-sharing per-destination Community value (route), then how to write it? If you directly match no-export , it will match with 11.11.11.0 , so you should use the exact-match keyword. If configured on R3 as follows: Select the route with the smallest neighbor IP address ( the address of the neighbor in the neighbor configuration of BGP , that is, the update source IP of the neighbor ) On Interface s0/0 R4 knows that to go to the destination, it needs to go to AS100 via AS300 to get the purpose. Match the previous character 0 or more times Ip as-path access-list 1 deny _600$ UDLD mode of operation The AS_SEQUENCE attribute will be passed to R7 along with the route 11.11.11.0 , so the packet is captured on R7 . The attribute of AS_CONFED_SEQENCE is not visible in the route of 11.11.11.0 , so the external AS treats the federation as a single AS (outside I don't know the situation inside the federation) ? You can use show ip bgp regexp to check the results of the configured regular expression. Neighbor 3.3.3.3 remote-as 345 Transparent mode VTP configuration revision number is always 0 R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. 1 About IP Routing 5 I can't ping because I found a subnet route after looking up the table at 172.16.1.1 . Therefore, the search is limited to the subnet route, and then the route is found to be mismatched. Therefore, the packet is discarded directly without going through the default route. . Switchport trunk encapsulation ? switchport mode trukn switchport nonegotiate When the number of prefixes received from the neighbor exceeds the maximum number 300 of 90% (default 75% ), generating a message log BPDUguard Locally find a route to the neighbor, and start preparing for TCP connection and monitoring remote peer 0100.e01e.6012.89 Neighbor 10.1.23.3 local-as 201 [no-prepend] [replace-as] [dual-as] 3 : MD5 verification. port-security does not support etherchannel the port-channel interfaces AS_PATH , and AS_PATH only when routing out this AS or BGP routers to update EBGP will change when neighbors in AS inside will not change, therefore, in the AS internal, anti-ring requires the use of split horizon. So how to solve the problem that R5 ca n't learn routing? ( If MED is empty , it is set to 0) * Network 172.16.11.0 mask 255.255.255.0 Route 2 : the AS_PATH : 500 the MED : 100 Internal RouterID : 172.16.8.1 The oldest EBGP neighbor means that it is probably the most stable BGP neighbor, so it is preferred here. Of course, this rule has poor controllability and is generally not used as a routing policy. The following happens and will skip this rule: MED Sw1(config-if-range)#channel-protocol pagp/lacp Sw1(config-if-range)#channel-group 1 mode desirable HSRP Trunking !! This is the direct link between R1-R3 Received a Layer 2 frame. R3 and R4 , R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . ? Knowledge review As a result, when PC2 sends data to its own gateway 0.254 , since the MAC of the gateway has been spoofed into the MAC of PC1 , the data is forwarded to PC1 , and PC2 is disconnected. If PC1 is smarter, transfer the data sent by PC2 to the real gateway, and run a message analysis tool locally to snoop the data sent by PC2 . Then, in the case of PC2 continuous network, God does not know. I feel the Internet traffic of PC2 , this is the man in the middle , the middleman attack.
