Ip address 192.168.100.254 255.255.255.0 Access permanent nontrunking mode and negotiate with the peer interface to make it a nontrunking link The number of addresses. The switch assigns MAC addresses in order Ip route 0.0.0.0 0.0.0.0 serial s0/2 RouterA passes the route 100.100.100.0/24 to C , and the NEXT_HOP remains unchanged. Router(config-router)# passive-interface fast 0/0 Router(config-router)# neighbor 192.168.123.2 Aging Type : Absolute SecureStatic Address Aging : Disabled RouterID : 1.1.1.1 Network 172.16.11.0 mask 255.255.255.0 // 100: 200 indicates that this is for the AS200 's 3.3.3.3 IP routing table ( IP Routing the Table ) / / Is to shield the route from the RIP re-released in addition to 1.1.1.0 , and re-release the local direct connection AS_SEQUENCE exactly the same, except that the list of AS numbers belong to the local Federation AS Define the network segment associated with the address pool To control, the most simple and convenient. Path attribute The Control field is composed. Update-source 100 i The idea of ​​configuration is that on R2 , you want to grab the fast0/0 port (that is, the one sent by R1 ) and go to the traffic of 30.30.30.0/24 . SW2 is the core layer switch, deploying DHCP relay About the configuration of PVLAN : When OSPF to IBGP when routes are heavy, because the OSPF of AD than IBGP of AD should be small, so there is no problem of sub-optimal routing path or loop: Fa0/20 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 ------------- Name server Therefore, from here we can see that the route summary is a risk of looping. One way to solve the above problem is to add a static route on the Layer 3 switch: ip route 192.168.0.0 255.255.0.0 null 0 , this way, when it receives access Vlan range supplement: Configuring a VTP domain name R3 and R4 , R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . To increase the reliability and redundancy of the network, we let R1 and R2 are 100.0.1.0 and 100.0.2.0 injected into BGP , here is the simulation of a redundant environment, that we can through R1 , also by R2 Go to 100.0. 1.0 and 2.0 networks. If a DHCP relay is also deployed on the switch, the switch adds the relay address to the DHCP packet. Summarizing on R3 suppresses all details, but if you only want to release partial details for a particular neighbor, you can use unsuppress-map Use as-path access-list to match routes Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only advertise-map test To confirm, the bridge responsible for notifying the topology change will continue to send TCN BPDUs before the bridge confirms the TCN . Next, the designated bridge will generate another TCN for its own root port , and the process is sent all the way to root . Finally: R4#sh ip b Neighbor 1.1.23.2 route-map test out Ip community-list 1 permit no-export ip community-list 1 permit 12:1111 Address family identifier. When the value is 2 , it indicates the IP protocol. Ethernet data link layer Configuration Example Next Hop Ip address 192.168.10.254 255.255.255.0 2 : Reponse message, send all or part of its routing information, a Response ! For Dot1Q MTU = 1522 Active is 10.1.1.252 (primary), weighting 100 (expires in 7.028 sec) Arp replies sent: 1 The Control field is composed. Additional instructions: Received WAS, IT A SENDS that the LAN containing the BPDU DATE The up-to-Port Information Stored for that. the In the this Way, the inferior IS Discarded Information, and Superior Information The IS ON propagated Network. " The R3 routing table is OSPF 's B segment route, then this B network route will be re-released back to the RIP domain,ccnp switch 300-115 tutorial, and ultimately to update Full IBGP interconnection between route reflectors in the AS Vlan 100 Distribute-list route-map test in Port role: None 300, ( aggregated by 300 3.3.3.3 ) // a summary route generated from AS300 , a BGP router 3.3.3.3 produced Another way is to use ARP ACL : 13 The destination IP address of the route , which can be the address of the natural network segment or the subnet address or The switch receives a DHCP packet, the discovery packet of option82 information precisely, the switch from locally originated option82 after information is removed, the DHCP packets forwarded to the DHCP Client . It can be seen that since we configured the summary, the as-set keyword was used to make the summary route inherit the detailed partial path attribute. Therefore, the generated summary route still retains the aggregate attribute, but there is no atomic-agg attribute. Obviously this attribute It is no longer necessary in the case of the as-set keyword. Information, so that ISP1 is hanging, so the data of the PC accessing the 100 network is switched to ISP2 , and the network is constantly s> 172.16.1.0/24 The implementation of diversified strategies at the level has been able to achieve very good path control effects, and it is a very scientific and highly recommended method to control the flow of data by controlling routing. In addition to this, there are many, such as: No default In 802.1D , the TYPE field uses only the highest and lowest bits to indicate TC and TC acknowledgment, and RSTP extends this field: BGP PA can measure or traffic statistics on IP traffic sent by BGP peers. Route-map COST2 permit 10 match ip address prefix-list 100 set extcommunity cost 1 5 As mentioned above, the secure address entry formed by the dynamically learned MAC address of the interface will lose the secure address entries formed by the dynamically learned MAC after the interface is up/down , but all interfaces are used. The switchport port-security mac-address is manually configured and the workload is too large. Therefore, this sticky mac address allows us to turn these dynamically learned MACs into a "sticky state " . It can be simply understood that I will learn dynamically, and after I learn, I will glue you up to form a "static". "(Effectively SecureSticky ) entries.
