ccnp switch exam simulation questions

By defining AS345 as a federated AS (large AS ) and a member AS (small AS ) in the federated AS , the problem of IBGP route delivery can be solved . 10.1.13.1 The MAC sublayer is responsible for the following tasks: Related commands : The process learns the external route, so the update source here is R2 . Network, which is consistent with topology expectations,ccnp switch exam simulation questions, but the underlying cause is still due to the learning of R2 compared to IBGP routes from R3 . As we R3 on the RIP routes injected into OSPF marked the Tag 1111 , then the next BGP of AS plan shown in FIG. FastEthernet0/0 When a local BGP route is advertised to an IBGP peer , the MED value must be carried . Type ( Type ) Trunks can be statically configured or negotiated through DTP . DUAL AS provides a migration solution: Allow R2 's BGP process to take into account both AS numbers, 200 and 201 , of which 200 Experiment 3 SW2(config-if)# ip address 10.1.1.252 255.255.255.0 Send Keepalive bag The Ip helper-address command is configured on the Layer 3 interface that receives the broadcast discovery packet sent by the client , or "blocks" the broadcast DHCP packet. For example, if it is a Layer 3 switch, use the access. interfacing PC , then you should configure the VLAN 's SVI interface. The optional parameter length is used to indicate the length of the optional parameter field Basic 28 Using ICMP protocol to detect 10.1.1.2 reachability (source address 10.1.1.1 to ping10.1.1.2 ) Track Object 's ID is 1 , associated to ip sla monitor 1 Aggregate-address summary address summary-only learner *>i100.0.1.0/24 ? After the MAC sublayer of A is added to the MAC address and the LENGTH field, it is sent to the data link. Network 12.12.12.0 mask 255.255.255.0 The election of the Root Bridge will not be said. Dialer Dialer interface Before the DAI is deployed , if the ARP spoofing behavior occurs on the intranet , for example, the PC sends an invalid ARP packet, the switch cannot detect and defend the defensive action. Since the AS_PATH attribute does not change within the AS (only when the route leaves the AS ), the AS inner loop has a horizontal splitting mechanism, and the route reflector actually relaxes the horizontal splitting principle. This will bring some hidden dangers to the loop. Therefore, the route reflector needs to use the following two attributes to prevent loops: 200 i 9 32 bits If a psec port is punctured into err-disable , you can use the following methods to restore the state of the interface: Dhcp-bindings all —Logs all packets that match DHCP bindings. Below is an example: Next, we SW2 on the vlan10 port removed, directly in fa0 / 2 on the no switchport access vlan routing * i We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Router bgp 300 Switch B receives the TCN BPDU , sends a TCN ACK to confirm, and forwards the TCN BPDU to its own root port. [Synchronization concept] After a BGP router learns a route from an IBGP neighbor, it is not enabled (not optimized) unless it learns the same route from the IGP again . This is to prevent the routing black hole problem described above. Ip address 192.168.100.254 255.255.255.0 This attribute may not be supported. Unrecognized BGP processes ignore update messages containing this attribute and are not passed to other BGP neighbors. Next hop If RP2 matching route exists in the BGP table, RP2 is advertised ; if RP2 hangs, RP1 is advertised. Trunk port processing frame process 3.3.3.3 B is RR , C and D are clients , BCD constitutes a route reflection cluster; a BGP route is advertised from C. 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. OSPF and OSPF The original attribute is i , so R3 and R4 learn BGP route 1.1.1.0 from R1 and R2 at the same time . After the decision, the traffic to 1.1.1.0 will be sent from R2 to R1 , so the sub-optimal path is obtained. (1) can learn the routing entries of R2 update, and the routing table is loaded with This feature uses the CDP table of the device to determine the reachability of the next hop. On R10 , the route is redistributed into OSPF . R11 learns 8.8.8.0 through OSPF . On R11 , the route is: RIP defines two types of request messages and response messages. Route redistribution R4#sh ip b 100 i In the in direction, the distribution list can only filter the route when the LSA is received locally. When the route is generated, the router's own routing table that implements the distribution list will be affected by the distribution list (but the local LSDB still has the LSA ), and router will still LSADB in Redirection enabled, 597.032 sec remaining (maximum 600 sec) Time to live: 14397.032 sec (maximum 14400 sec) Also, when R2 hangs, the entry of 172.16.2.0/24 is invalid, and the data destined for the 2.0 subnet is matching 172.16.0.0/16. Note that with route-map , the last is implicitly killing any , while the suppress-map is different. Experimental phenomena: 0 , regarded as infinity 200 Configure the switch to verify that the source MAC address in a DHCP packet received on untrusted ports matches the client hardware address in the packet. The default is to verify that the source MAC address matches the client hardware address in the packet. !! Match the exit of the packet Matching with the detailed route 172.16.32.0/24 , so eventually these two routes will be filtered out, which is inconsistent with our needs. In fact, this is the drawback of using a standard ACL to match the route, you can only match the network number of the route, and can not further match the prefix of the route. About IP Routing 8 bits Metric problem In a route-map statement, if there is no match statement, match all When a data frame is sent from the Access port, the switch strips the VLAN tag of the frame and then sends it out. Administrative distance problem The simple horizontally separated rule is that the update message sent from an interface does not contain the network contained in the update received from the interface. In other words, the route I received from this interface will not be from this interface. Send it back. R2 will "translate" the two OSPF routes 3.0/24 and 4.0/24 into RIP and pass it to R1 . R1 will also be able to learn 3.0 and 4.0 routes. Note that the re-released execution location is performed on R2 , that is, at the demarcation point of the routing domain. In addition, the route re-distribution is directional. For example, after we have performed the relevant action, R3 still has no R1 route. Need to further re-publish the RIP route on R2 .
