After the Port-Security feature of an interface is activated, the default maximum number of secure addresses is 1 , that is, the interface uses its dynamically learned MAC address as a secure address without manually configuring a secure address. This interface is equivalent to being exclusive to the MAC (the device to which it belongs). And the default violation is shutdown R* 0.0.0.0/0 [120/1] via 192.168.12.1, 00:00:03, Serial0/0 This command can be used in the following ways: Ip prefix-list 1 permit 100.0.1.0/24 route-map test permit 10 No passive-interface fast 0/24 Router bgp 100 When both the primary and secondary addresses are present, the RIPV1 router will use the mask of the secondary address of the interface that receives the route update packet locally (this has been verified in the above experiment). Static route configuration 20 [Experiment 6 ] There are subnet routes, the subnet route prefix length is different (matching and mismatching), and the matching route is taken. When a data frame is sent from the Access port, the switch strips the VLAN tag of the frame and then sends it out. access-list 1 deny 172.16.32.0 0.0.0.255 In fact, this is more a problem, because such an approach, in fact, the last 8 bit group no matter what, will be live match, he is even more imprecise. ( Well-known discretionary ) Neighbor xxxx advertise-map xx exist-map xx Modify the TAG of all external LSAs generated by the ASBR . ? 192.168.2.0/24 //The details are not released. The road selection has met our expectations. Other configuration commands After the command is configured, the newly learned MAC address is also sticky . Access-list 1 deny 192.168.0.0 0.0.255.255 Note: If it is an EIGRP environment, you need to implement unicast update, then the route update interface can not be PASSIVE (this is different from RIP ), directly use the neighbor command to specify the neighbor. If the interface is PASSIVE , even if the neighbor is manually specified , the EIGRP neighbor relationship cannot be established normally . These modes generally only be on high-end Cisco device applications , such as 7200 series routers . Or 12,000 Series routers . Command : ip route-cache optimum show ip cache optimum On the catalyst switch, you can use the portfast keyword to manually configure it. Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . We look R5 are BGP table: The PC has obtained the address and viewed dhcp snooping bingding databsae on SW1 : Type ( Type ) [Experiment 6 ] There are subnet routes, the subnet route prefix length is different (matching and mismatching), and the matching route is taken. Address-family ipv4 unicast Compatibility On the debug information we found: BPDU packet The following is the change of the packet after MD5 authentication is configured (all TCP packets have MD5 HASH field added): Non-exist-map tabel-map Determine if the frame has a VLAN tag . Path That is, a site address,ccnp tshoot pdf free download, the MAC address, is reserved at this level to identify the only site on the network. 8 Then IOS will automatically change the command to Set ip next-hop ip1 ip2 ...... RIP-1 only sends RIPv1 updates 3.3.3.3 But there is a loop in the second floor environment. 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: Another role of Gratuitous ARP is that some manufacturers use it to prevent ARP spoofing. For example, on some routers, a Gratuitous ARP- based anti- arp spoofing solution is configured, and the router (interface) will send Gratuitous ARP at a certain interval , in order to refresh the arp table of the bottom PC to keep the gateway IP corresponding. The MAC is always correct, of course, this anti- arp solution is quite awkward.
