3.3.3.3 Ip prefix-list 100 permit 100.100.100.0/24 route-map COST1 permit 10 ? Ip prefix-list 1 permit 1.1.1.0/24 route-map test After the maximum number of allowed MAC addresses of the port-security interface is set , the security address entries associated with the interface can be obtained as follows: [Experiment 5 ] There are subnet routes, the subnet route prefix length is different (but both match), and the longest match TYPE SW2(config-if)# glbp 1 10.1.1.254 Modify the default value of the MED value Origin IGP, metric 0, localpref 100, valid, internal, best Directional strategy. COMMUNITY attribute is set . 4 th 8 value bit group, RFC1997 predetermined front 2B represents AS number, after 2B represents the basis for management purposes set identifier, the format of AA : NN , and CISCO default display format is NN : AA , may be used The global configuration command ip bgpcommunity new-format changes the CISCO default format to RFC format. The security address entry thus formed (which is SecureSticky ) will not be lost even if the interface is flipped. If wr saves the configuration and the command is written to config.text , the security address will not be lost even if the device is restarted. Run the switchport port-security mac-address command to configure a static security address entry. Access-list 11 permit any route-map adv permit 10 match ip address 11 router bgp 12 Link aggregation mode Tag rewrite with Fa1/0, 10.1.13.3, tags imposed: {} via 10.1.12.2, FastEthernet0/0, 0 dependencies FastEthernet0/0 Learning from other sources, the routing source is incomplete (confirm that the source of the routing information is incomplete). ( Republish IGP or static ) Circuit-ID type Can affect BGP routing (before the equivalent load balancing), somewhat similar to " tie breaker " in the path selection, is to break the tangles when tangled When the router is adjacent to the host, they learn in some way. 30.30.44.45 /24 Neighbor 10.1.13.1 remote-as 100 One-arm routing Hostname R2 interface s0/0 However, at this time, R3 will also receive the summary route from R2 release, which may form a routing loop, so it needs to be filtered out. Add configuration on the BGP process on R2 : Static routes A single RR may have a single point of failure problem, so from the perspective of redundancy, there can be multiple RRs in a cluster , Client and each BGP routing table entry for 1.1.1.0/24, version 2 RouterA passes the route 100.100.100.0/24 to C , and the NEXT_HOP remains unchanged. The process of processing a VLAN frame by a trunk port is as follows: Option82 and related issues in a non-relay environment One solution is that SW1 does not insert opiton82 , another method is to use the configuration on the DHCPserver : 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. . Use the global configuration command: err-disable recovery psecure-violation Ip dhcp snooping If the access layer switch is connected to a single link, there is a single point failure of the single link failure. If any aggregation device is down, it will directly cause the downlink access network to hang. Regular expression Route-map test permit 10 Router bgp 345 Network ------------- 100 General BGP routers do not accept containing its own AS routing information number, but can neighbor routing sources neighbors allowas-in a few of my as numbers , to make an exception. Because ARP 's response does not need arp request is a prerequisite to send directly,ccnp switch price, so an attacker can construct arp reply message is sent to the target of attack, to refresh the attacker's arp table, to achieve the same arp deceitful purposes. Elect a designated port for each segment Comparative principle Router bgp 12 table-map PA Origin attribute (priority: IGP > EGP > Incomplete ) 3.0.0.0/24 is subnetted, 1 subnets By default, the RIP running on the CISCO router sends v1 and receives v1 v2 . If the display is declared as v1 ( use the version in the RIP process) 200 Route summary At this time, actually R1 's loopback port to R2 needs at least 2 hops, then this time you need to configure both neighbor xxxx ebgp-mul 2 On R2 and R3 , there are two OSPF processes. If shown, one is OSPF1 and the other is OSPF2 . Note that this dual process is mainly implemented on the two ASBRs R2 and R3 . EtherChannel Network 100.0.1.0 mask 255.255.255.0 Y Lab topology and description If you want to delete multiple communities (not all), you can write multiple items in one community-list , such as R2(config-router)# distribute-list 1 out [Experiment 2 ] Neighbor + Route-map achieves the same function Fa0/20 Configure the primary VLAN to associate the Layer 2 secondary VLAN to the primary VLAN. 100 i SA sends the original switch MAC of the frame command How to judge whether there is arp spoofing in the intranet The default bridge priority of the switch is increased to a higher value than the default ( 32768->49152 ) so that the switch does not become Root. Not used (set to all 0s ) 5.5.5.5 R1(config-router)# redistribute connected subnets The route originated from the local (such as the local network , or aggregate ), that is, the next hop is 0.0.0.0 ( in the BGP table , the current path) Example 1 : Using route-map to associate neighbor filtering routes Lease(sec) Type Each group of GLBPs can have up to four member routers as ip default gateways. These gateways are called AVF ( active virtual forwarder ). Message age IP routing table S 172.16.3.0/24 [1/0] via 172.16.23.3 Limit of inhibition: 2000 R3 , R4 running the OSPF , the R3 on each can learn from the R1 and R2 of looback Aging Type : Absolute SecureStatic Address Aging : Disabled Configuration example 1 : as-path access-list with filter-list Routing via 192.168.12.1, Serial0/0 Test purpose: VLAN information transfer The configuration of R2 is as follows: Planning Principles ? A the LLC sublayer own data to be transmitted is encapsulated, wherein the DSAP byte is filled B return to the SAP , the SSAP bytes are filled to their open the SAP , and then sent to MAC sublayer. None Weight Router bgp 123 The switch sends data frames according to the discovered outbound interface. If there are routes with the same prefix as follows (the default is sorted in reverse order of route acceptance order) The least significant bit of the LSB indicates the TC flag; the most significant bit of the MSB indicates the TCA flag. C 1.1.1.0 is directly connected, Loopback0 2.0.0.0/32 is subnetted, 1 subnets Origin IGP, metric 0, localpref 100, valid, internal Router bgp 100 In the one local BGP routes advertised to EBGP the Peer time, whether they carry MED values , need to be determined under the following conditions ( not EBGP 20.20.20.0/24 200 i Similarly, if ip route 3.3.3.0 255.255.255.0 null0 is the same. Redirect time 600 sec, forwarder time-out 14400 sec Preemption disabled Network Authentication (16 octets) Federal configuration and implementation The range of prefixes to match, ranging from ge-value to 32 Route-map test permit 10 Router(config-dhcp)#network [network address][subnet mask] In CISCO IOS , CEF can hash the source and destination IP addresses and import the hashed results into a load balancing table for load balancing. This table has 16 hash buckets , each of which points to an adjacency, and multiple buckets can point to an adjacency at the same time. You can use the show ip cef route prefix internal hidden command to see: Match ip address 1 Re-routing interface connecting the local release, static routing weight is 32768 .
