This summary route generated locally is 172.16.0.0/16 , NH=0.0.0.0 , weight= default value 32768 , origin=i . The detail route is marked as " s " and is therefore suppressed. Option 82 sub-option 2 : Remote ID , which is generally the MAC of the access layer switch that inserts the option 82 information . The above match statement is used to match the summary route. Router rip Configure the SVI interface corresponding to the VLAN . Access permanent nontrunking mode and negotiate with the peer interface to make it a nontrunking link To summarize on R3 , use aggregate-address summary-only as-set , then the BGP table on R3 : 192.1.168.2 3 0003.47d9.c8f1 2BB648AB interface-id 584a38f0 END FastEthernet0/0 Advantages and disadvantages Unused Another way is to use ARP ACL : To other neighbors Violation Mode : Shutdown !! After the violation,ccnp tshoot lab manual pdf, the default is shutdown Aging Time : 0 mins By default, only O and O IA routes in OSPF are redistributed into BGP. Frame format The Response packet contains a maximum of 25 routing entries. No synchronization Address 200 i Configure static routes by using the associated outbound interface. Route-map test permit 20 DUAL AS : 000a.8a07.8280 802.1W ? Set traffic-index 30 Network 100.0.2.0 mask 255.255.255.0 neighbor 10.1.13.3 route-map test out Authentication Configuring DAI logging After completing the configuration, R2 show ip route There are 2 forwarders (1 active) BGP router identifier 12.12.12.12, local AS number 64512 BGP table version is 2, main routing table version 2 ? Neighbor routing source neighbors allowas-in a few of my as numbers On Demand stub Routes Store all routing entries, as well as their properties. Local updater ID is 0.0.0.0 (no valid interface found) The OSPF metric on R4 going to 3.3.3.3 becomes 101 , which is larger than the metric going to 5.5.5.5 . Therefore, R4 goes to Block all ARP requests or on the DAI untrust interface (note the separation from DHCP snooping 's untrust interface) Knowledge review Configuration example 5 (in the single routing protocol environment - OSPF out direction distribution list) 200 i Match ip address prefix-list 1 Port // IBGP neighbors, using loopback0 to build neighbors Synthesis example 2 : Test purpose: VLAN information transfer Route summary 23 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. Origin IGP, metric 0, localpref 100, valid, internal, best Weighting 100 (default 100), thresholds: lower 1, upper 100 Match ip address prefix-list 1 router bgp 1 The IGP Origin, Metric 0, localpref to 100, Valid, Internal, Best Originator: 1.1.1.1, the Cluster List: 2.2.2.2 Topology change mechanism (detection) BGP anti-ring is implemented through AS_PATH , and AS_PATH is only changed after the route leaves the AS . Therefore , IBGP does not have EBGP anti-ring capability in the AS . To prevent loops, BGP routers will not be from IBGP neighbors. The learned route is advertised to other IBGP neighbors. Match ip address 1 set metric 10 Allows up on a single switch . 8 th 802.1q to ISL vlan mappings Cisco Private R1(config-router)#distribute-list 1 in ? // All interfaces External 30.30.30.0/24 Request specific routing information: When it is necessary to know the information of a specific route or some specific routes, the request message will be sent together with the routing entry of the specific address. The device that receives the request will process the entries one by one according to the request message and form a response message. Example 1 : Policy-list is only supported in BGP . Other IP routing protocols do not support this feature. 200 i 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 Certification *>i We can let DAI do further verification by configuring some additional options . There are three optional keywords, dst-mac , ip , src-mac SW1#show int trunk As you can see, the route carries the atomic-aggregate attribute, which is used to inform the downstream neighbor that this is the route attribute that summarizes the route and loses the detail. At the same time, the aggregator attribute identifies the summary location ( the RouterID of the AS and the summary router ). Whenever a route is reflected by the reflector, the cluster -ID of the reflector (the cluster) is added to the route's Cluster-list attribute. 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: Network 4.4.4.4 0.0.0.0 area 0 Show ip dhcp database Displays recent activity on the DHCP database R1(config-router)#summary-address 10.0.0.0 255.0.0.0 tag ? Router eigrp 100 In R3 and R5 between increasing an IBGP connection, thus R3 and R5 of BGP routes do not need to pass by R4 (albeit over a packet still R4 forwarding, but R4 terms, R3 passed to R5 of these packets, Just an ordinary IP message). It should be noted here that BGP is different from IGP . IGP is like OSPF . To establish a neighbor relationship, two routers need to be directly connected. BGP does not need to be directly connected because it is a connection established based on TCP .
