ccnp switch 300-115 gns3 labs

PC2 is a new host access, arranged 192.168.0.1 address,ccnp switch 300-115 gns3 labs, the address after the completion of the configuration, PC2 transmits to the network a Gratuitous ARP , to prevent someone within the network using the same IP address, the Gratuitous ARP is senderIP and target IP All are themselves, senderMAC is its own MAC . TCP RFC2082 ( Optional transitive ) No default Router bgp 100 Metric LocPrf Weight We can affect the routing by setting the LP value. For example, the same implementation allows R4 to access 100.0.1.0 and go to R3 , accessing 100.0.2.0. None ? When we set the number of MAC addresses allowed on the interface to 1 and set a secure address for the interface, then this interface will only be for that MAC. Neighbor 10.1.12.2 advertise-map RP1 non-exist-map RP2 Abc+d ? 100 10.1.25.2 Do not advertise to any peer (well-known community) Do not export to next AS (well-known community) parameter The secure address formed by the dynamically learned MAC is valid. If the MAC is in a failed state within 50 minutes (for example, the host is offline), the secure address is cleared after the aging time expires. In 802.1D , a non-root switch can generate BPDUs only after receiving the BPDUs sent by the root bridge from the root port . In RSTP , even if the non-root switch does not receive the BPDU from the root switch , it itself sends the BPDU with the " hello interval" period (default 2S ) . *>i100.0.2.0/24 VLAN Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows The VLAN ID , which is 12 bits long, indicates the VLAN to which the frame belongs . In VRP , the configurable VLAN ID ranges from 1 to 4094 . IP routing table Fa0/20 1-4094 <0-4294967295> 32-bit tag value Static routes 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 . Configuration example 1 ( -RIP in a single routing protocol environment ) Access Switch SW1 is turned on DHCP Snooping , inserted Option82 ; A CFI of 0 indicates a classic format. Match interface : To distribute any routes that have their next hop out one of the interfaces specified, use the match interface command in route-map configuration mode . The understanding is that the match interface matches the next hop out interface is the route of this interface. entry Neighbor 1.1.1.1 route-reflector-client 3.3.3.3 On CISCO IOS , interface x interface mode: To summarize on R3 , use aggregate-address summary-only as-set , then the BGP table on R3 : 0 100 0 100 i Figure 2 R1 and R3 are the same AS , and the route of the 13 network segment is updated to R2 at the same time . The experimental effect is also in accordance with the rule description. If it is in the IBGP environment, that is, R1 , R2 , and R3 are all in one AS , then the rule Rules do not apply TCN BPDU Router ospf 1 We can let DAI do further verification by configuring some additional options . There are three optional keywords, dst-mac , ip , src-mac Metric IP protocol number 89 ------------------ 00:B0:64:04:09:99 Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . The configured commands are simple: RSTP immediately accepts these suboptimal BPDUs and returns a better BPDU . Ip prefix-list 10 seq 5 permit 172.16.10.0/24 ip prefix-list 11 seq 5 permit 172.16.11.0/24 route-map test permit 10 If the route is passed from an IBGP neighbor and describes the destination outside the AS *>i When LINK1 DOWN is dropped, SW2 will not receive the BPDU from ROOT , so it considers its root and starts to SW3. Origin IGP, metric 0, localpref 100, valid, internal Only vlan1 and vlan10 Multiplication character 3 : MD5 verification. What is the routing table for R3 ? In fact, without any impact, R3 can learn the routing of the entire network. As for why, I believe that it has been explained very clearly. The following uses an example to illustrate the application of SSAP and DSAP . Assuming that Terminal System A and Terminal System B are to use a connection-oriented and reliable data transmission service, the following process occurs: Neighbor 5.5.5.5 remote-as 345 case study Interface loopback0 The number of addresses. The switch assigns MAC addresses in order 100 i Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only Therefore than MED , 2 of MED small, 2 is the best path 0 100 i ? CFI As shown in the figure on the left, if the PC wants to Telnet the switch, first the PC should be able to ping the switch. Secondly, the VTY should be activated on the switch and the password should be configured. Then we create a VLAN 10 on the Layer 2 switch , assign the F0/1 port to VLAN 10 , and configure an IP address for the logical interface of VLAN 10 of the Layer 2 switch , and the IP of the same network segment as the PC . In this way, the PC can access the switch. But the problem is coming, so that the PC and the switch are on the same network segment and the same VLAN . In case there is a conflict between the IP address configured by the PC and the switch, we can consider dividing the switch into one. Separate VLANs for managing these switches. This VLAN is suitable for the entire traffic network, unified VLAN and unified IP.Planning, it is the management VLAN , so the management VLAN is not a specific VLAN , not VLAN1 , which is a misunderstanding of many people. In general, we will use a more "unprecedented" VLAN ID and IP , such as VLAN255 in this lab , and the network segment.
