Metric * i IBGP horizontal segmentation 200 i BGP has three management distances, 200 learned from IBGP and 20 learned from EBGP . This is because the design concept of BGP works. Ip dhcp relay information trusted Route-map test permit 10 match interface Serial0/0 router ospf 1 The front is to use static routing. If dynamic routing protocol is used, the situation is different. For example, IGRP or EIGRP , the network specified by the ip default-network command must be obtained through IGRP or EIGRP (declaration, learning or redistribution). ), the default route can be dynamically passed to other protocol routers. Load balancing can be modified on AVG , but it is recommended to configure on all routers. Configure a static default route locally, such as ip route 0.0.0.0 0.0.0.0 null0 distribute-list Matching 100 , 101 , 102 , 103 , 104 , 109 which AS_PATH Disable port MED * i Then on R4 , you can only learn 1.1.1.0 . The thing we have to do is very simple. These subnets are continuous. It is enough to pick out the first two or three network numbers to calculate: Switch B receives the TCN BPDU , sends a TCN ACK to confirm, and forwards the TCN BPDU to its own root port. This type of data transmission service does not need to establish a connection, but it adds an acknowledgment mechanism to the transmission of data, which greatly increases the reliability. The default is 10 , this default value is generally sufficient. Y 3.3.3.3 CASE3 : Forward Delay time listening to the learning state, or learning state to forwarding state required time defaults to 15s . Written in front of the words: O 2.2.2.2 [110/65] via 10.1.12.2, 00:05:16, Serial0/0 (interface) ip load-sharing per-packet After aggregate-address 192.168.0.0 255.255.0.0 , R1 can learn summary routing and 2.0 Use the clear port-security configured command to clear all manually configured security address entries. Use the clear port-security all command to clear all security address entries. / / Detailed release Example 1 : Next Hop In CEF , there are two main types of load balancing, based on messages and based on purpose. Match ip address prefix-list 11 set community 100:11 Configure the maximum number of secure addresses allowed for Port-Security . Private-vlan primary RFC1723 defines several compatibility switches Bgp inject-map RP_mingxi exist-map RP_huizong copy-attributes 10.1.13.3 SW1(config-if)# ip address 10.1.1.253 255.255.255.0 ...... R3 and R4 update the routes in AS1 and AS2 to R5 and R6 at the same time . If R5 is required to go to AS1 , take route R3 and go to AS2 . length 10.1.13.1 The route obtained by the BGP speaker from EBGP will be advertised to all its BGP neighbors (including EBGP and IBGP ). Define multiple serial numbers under route-map . The serial number has a priority order when performing matching actions. Two-point bidirectional routing re-release implementation 98 None : 000a.8a07.8280 None Path control 77 Hostname R2 interface s0/0 By default, only med of routes from the same AS are compared. If you want to compare MED for all paths , you should configure this command. Also, if this option is used, it is recommended to do this throughout the AS to avoid routing loops. PAgP mode: Commands Disable port It can be seen that the AS_CONFED_SEQENCE attribute is used in the federal inner ring (this attribute will not be federated), while the above Due to the existence of the principle of horizontal splitting, BGP requires that the IBGP be fully interconnected within the AS (here, the neighbor command specifies). (The root cause is in Port-Security Match ip route-source The configuration of R2 is as follows: // match AS ( 100,1 ) and ( 200,1 ) We mainly analyze: 5.5.5.5 Figure 2 R1 and R3 are the same AS ,ccnp switch flg, and the route of the 13 network segment is updated to R2 at the same time . The experimental effect is also in accordance with the rule description. If it is in the IBGP environment, that is, R1 , R2 , and R3 are all in one AS , then the rule Rules do not apply 10.1.23.3 from 10.1.23.3 (3.3.3.3) Destination Address (Route Prefix): This is the destination network number associated with the route entry. A complete route prefix consists of: network number + prefix length A default route will be published into the RIP and passed to other routers. For example, R1 , R2 , and R3 run RIP and open loopback on R1 . AS100 sends 10000 routes to R2 . If R2 only wants to collect 100 routes and the rest is filtered, then the general practice is to execute the in- direction filter on R2 , because AS100 is uncontrollable for AS200 . However, this method is actually a waste of link bandwidth and network resources. CISCO Note: The DHCP option-82 feature is supported only when DHCP snooping is globally enabled and on the VLANs to which subscriber devices using this feature are assigned. The command distribute-list out works only on the routes being redistributed by the Autonomous System Boundary Routers (ASBRs) into OSPF. It can be applied to external type 2 and external type 1 routes, but not to intra-area and interarea routes. When a router connects through a multi-access medium such as Ethernet, a dynamic mechanism is needed to discover each other, such as ARP . ARP can map Layer 2 addresses to IP . If it is a frame relay multipoint link, the adjacency relationship can be learned by using an address resolution protocol, a mapping table, and the like. 10.1.12.1 from 10.1.12.1 (1.1.1.1) If DHCP snooping is turned off or this is a DHCP- free network environment, such as a pure static IP address environment, use ARP Native vlan Neighbor 10.1.12.2 route-map test out If the network implements IBGP full interconnection ( IBGP neighbor relationship is established between each other ), then synchronization is meaningless and synchronization can be turned off. So today's CISCO IOS turns off synchronization rules by default. 100$|400$ With the above configuration, the analog R3 received from AS200 and AS600 route, in case R3 on filter out from AS600 route, due AS600 route, the AS_PATH trailing end are 600 , so the regular expression can be used: _600 $ , Underscores are used to match spaces. Note, however, that the as-path access-list is also implicitly deny any by default , so be careful to deny the route from 600AS and leave the other routes.
