When track1 is true , that is, 10.1.1.2 is reachable, the data of the PC accessing the 100 network is lost to 10.1.1.2 . If track 1 is hung, the next next-hop is switched. A macro command that specifies the interface mode as access and enables the portfast feature. Neighbor ip remote-as as-number So R2 can ping through 3.3.3.3 Private VLAN concept The EBGP neighbor learns 2.2.2.0 . The RIP management distance is 120 and the EBGP is 20. Therefore, EBGP routes are preferred . How to make R1 preferred RIP Ethernet frame format Next Hop When a network is directly connected, the interface is not "activated" and attempts to establish a neighbor relationship. BGP neighbor relationships need to be manually Set ip next-hop 10.1.1.2 10.2.2.2 interface fast 1/0 Ip local policy route-map x Default behavior: source IP address pair ( src-dst-ip ) ? Matching as long as the contents of a , b , c , d appear Switch B receives the TCN BPDU , sends a TCN ACK to confirm, and forwards the TCN BPDU to its own root port. This experiment mainly verifies that automatic summarization does not occur at the boundary of the main class network: Switchport access vlan 10 10.1.12.2 Switch(config-if)# switchport protected Optional non-delivery, generally used between AS to affect routing. ? 10.1.13.1 B and C receive this better BPDU and continue to flood the network. At 1 o'clock, it can be considered that this address represents a broadcast address or a multicast address in the Ethernet, or represents a broadcast address or a function address in TR and FDDI . The next bit is the G/L bit (also known as U/L, where U is global). When this bit is set to 0 , it represents a global management address. 100 After the configuration is complete, use clear ip bgp * soft to reset it softly. RFC1721 / / used to define the condition prefix to be injected : Disabled Match ip address 2 set metric 3 Summary of 192.168.0.0/16 on R2 Remarks Etherchannel port does not support pvlan All VLANs BGP Set metric xx Set origin set tag Neighbor maximum-prefix 300 90% warning-only When we deploy PBR on an interface , if this interface receives a packet, it will: TRUNK Ip address 10.1.34.4 255.255.255.0 Active Consider a simple model: The first 8 bits of the route must match the first 8 bits of 172.0.0.0 , the other bits are not concerned, and the mask must be /8 . Detailed rules Match ip address prefix-list 11 set community 100:11 Clear ip bgp {neighbor-address} soft in/out specifies a specific neighbor, it is recommended Complete the basic configuration Origin attribute (priority order: IGP > EGP > Incomplete ) It means for VLAN100 traffic, not to log the ARP ACL discarded packets match Port Vlans allowed and active in management domain Fa0/20 1,10,20,30 Once the portfast port is connected to the device, the interface can bypass the listening and learning states and enter the forwarding state directly . Switch(config)# vtp domain cisco Activates self-recovery of the err-disable interface due to arp-inspection violations . Maximum-paths ibgp 2 , then on R4 , in the ip routing table, there will be load balancing of BGP routes, but note that R4 is Can be configured in global mode or in interface mode, the difference is as follows: global configuration: spanning-tree portfast bpdufilter default 200 i PVLAN considerations In RSTP , topology changes are triggered only when a non-edge port transitions to the forwarding state. In other words, if a port loses its connection, it is no longer considered a topology change, which is different from 802.1D . Fa0/20 ^100_ IBGP session principle 5.5.5.5 If there is an EBGP connection between R2 , then a routing loop occurs, and R1 and R2 will receive the summary route and accept the routing update. This is because this summary route does not carry any information about AS100 and AS200 . Authentication Major Points Dhcp-snooping 0 , regarded as infinity Note inconsistent with err-diasble difference is, ERR-disable will disable off the entire interface, and inconsistentport is for a particular VLAN 's. There are 1.1.1.0 , 2.2.2.0 routes on R1 . All BGP neighbors TCPsession and BGP neighbor state are reset Ip address 10.1.13.1 255.255.255.0 The access layer switch uses a dual link to connect to two aggregation devices to form a Layer 2 environment with physical link redundancy, which solves the problem of single link failure. *>i Router bgp 200 Access-list 11 permit any route-map adv permit 10 match ip address 11 router bgp 12 Modify the default value of the MED value 1.1.1.1 (metric 129) from 2.2.2.2 (2.2.2.2) Set metric sets the metric of the routing protocol HOLDTIME CISCO defaults to 180s ( 3 times KEEPLIVE timer ), which is included in the open message. Passive interface 100 Ip rip triggered The data is two-way. When considering traffic, pay attention to the round trip of traffic. Bgp confederation identifier 345 neighbor 4.4.4.4 remote-as 64512 Matches the network number and prefix length in the route prefix to enhance the accuracy of the match. Switch(config)# vtp password x When ISP1 fails, GW senses through tracking , so the data is switched to ISP2. Peer using Route-map in the case of ) : From the message we can see that the size of this IP packet is 1500 bytes. 7 Neighbor 10.1.23.3 local-as 201 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale The LP attribute of the route is preserved throughout the federation *> 100.0.1.0/24 Enabling BPDU filtering on an interface is the same as disabling spanning tree on it and can result in spanning-tree loops. Route-map test permit 10 VLAN Interface -------------- Experiment 1: host-dependent Strictly speaking, path control is a very big topic. In the deployment of a large network, it is often necessary to consider the control of the data traffic access path in order to make more rational and scientific use and allocation of network resources. At the same time, it enhances the reliability, redundancy and robustness of the network. DAI 's work depends on DHCP snooping Vlan 10 Can be configured in global mode or in interface mode, the difference is as follows: global configuration: spanning-tree portfast bpdufilter default Redistribution of class, classless routing protocols 46 2. Pass the RIP update with an unnumbered address ( invalid source ) If you try to activate 8021.X on a port-security interface, you will get an error and the 802.1X function will not open. The default is 180s , which can also be called expiration timer time limit timer or timeout timer. Distribute-list Experiment 1: host-dependent We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows By MED influence route selection In the figure above, we started the re-release action on R2 . We "inject" the OSPF route into the RIP process, so that Ip route 1.1.1.0 255.255.255.0 serial 0/0 Port number 520 Supplementary explanation of the role of the as_set keyword: 3 The next-hop attribute can be changed by next-hop-self Then IOS will automatically change the command to Set ip next-hop ip1 ip2 ...... Route summary Ip prefix-list 1 permit 100.0.1.0/24 route-map test permit 10 Vlans allowed and active in management domain All dynamically learned MACs on this interface will be converted to a sticky mac address to form a secure address. The configuration of R2 is as follows: Therefore, when the route lookup mode of the router is classless or the classless route lookup mode, the default lookup action of the router is the longest match criterion. For example, in the above figure, when R3 receives a packet and goes to 172.16.1.1 , then in fact, 172.16.1.1 is "dropped" in the network of 172.16.1.0/24 and 172.16.0.0/16 ,ccnp route 300-101 dumps pdf free download, both seemingly Yes , but 172.16.1.0/24 obviously has a longer match, so the packet is eventually dropped to R1 . Similarly, if there is a data packet going to 172.16.2.1 ? Since the entry of 172.16.2.0/24 is the highest according to the longest match principle, the data is thrown to R2 .
