Which exchange method will be used FastEthernet1/0 The configuration of R2 is as follows: Routing Policy After completing this configuration, we can show it: R5 routing, naturally the last is the route from R5 , reflection to R3 is no problem. (64513) 200 i Cause: After the ARP Request is sent , the ARP Reply is prepared for a large number of reasons: scanning on the same network segment (host), scanning across network segments (network device) Experimental example: Calling in the distribution list CAM and TCAM Port The default is 10 , this default value is generally sufficient. ? 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 . To verify which outbound interface is used for a particular traffic in destination-based load balancing, use Must be a zero field. External route tag. This idea has been applied to dynamic routing protocols such as OSPF . Careful children's shoes will find that after you deploy route summarization in OSPF , it will automatically generate a summary route pointing to null0 locally . The reason is explained above. the same. Affect traffic 12 by modifying the LOCAL_PREF attribute Let's analyze that SW1 inserts the DHCP request message from the PC into option82 and then sends it to SW2 . Via SW2 Desirable actively attempts to make the link a trunk (default mode), sending DTP frames, and if the adjacency interface is trunk ,how to master ccnp tshoot pdf free download, desirable , or AUTO , then the interface becomes a trunk . FastEthernet1/0 R 1.1.1.0/24 is possibly down, The default native vlan is vlan 1 Set local-preference 300 Spanning-tree Response message and check Neighbor 10.1.23.2 remote-as 201 // R3 means that the remote-as of R2 is 201 , which is the secondary AS. Establish BGP neighbor relations SW1(config-if)# switchport native vlan 1 The problem that the static route associated with the outgoing interface is in the network Configuration command Traffic share 1 Take the configuration of R2 as an example: No synchronization no auto-summary RFC1723 defines several compatibility switches Note that the data exchange process is different for different products. The above process is the result of testing on the CISCO device (server). Because ARP 's response does not need arp request is a prerequisite to send directly, 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. Path RIP Version 2 Protocol Analysis $ Run RIP between R1 and R2 (declare direct connection and their respective LOOPBACK ). At this time , the update package sent by R1 has the source address of 192.168.12.1 . Suppress-map unsuppress-map advertise-map inject-map RIP V1 supports a maximum of 6 and defaults to 4 equivalent load balancing. And does not support verification. V2 supports verification. Router bgp 200 : 1 to 3 Understand the invalid arp entry Ip route-cache flow show ip cache flow Router bgp 200 1.0.0.0/24 is subnetted, 1 subnets 17:57:27 Application example Multilink Multilink-group interface Neighbor ip remote-as as-number (1) can learn the routing entries of R2 update, and the routing table is loaded with Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale Configuration Example Sw(config)#vtp transparent If multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred . The first 8 bits of the route must be exactly matched with the first 8 bits of 172.0.0.0 . The other bits do not care, and the mask length must be greater than 24. Note that here Reset BGP connection R4 to R3 configured as Client , then it will be able to break through the limitation of split level, will learn from R3 route reflector to R5 , will learn from R5 route reflection of self- R3 . Let's look at R5 of the BGP table: Mapping is only valid locally Switchport port-security mac-address sticky R4 can learn from R1 and R2 of the 100.0 network routing, and the previous experimental results, we know, without any deployment strategy, R4 preferably RouterID small R3 as destined 100.0 segment BGPpeer , then Can we influence the routing preferences by controlling AS_PATH ? Next, we use route-map to make a policy on R1 , which takes effect on R3 and modifies the AS_PATH path attribute of the 100.0.1.0 route . Eventually, R4 goes to the 1.0 network to go to R2 , and goes to the 2.0 network and still goes to R1 .
