DAI supports on the access interface , trunk interface , EtherChannel interface , and private VLAN interface. This is the ICMP redirect message sent by R1 to R3 . Note that the Gateway address field in the header is filled with the next hop IP that is closer to the destination than the destination . Sh ip bgp neighbors {address} advertised-routes R3 summarizes the details of R1 and R2 (summary command plus AS_SET keyword), so that the BGP summary route generated by R3 inherits the detailed AS_PATH attribute, and the packet capture on R4 will find the summary route. = 300 {100,200} AS_PATH : look at the results of the capture, found article summary route AS_PATH attribute consists of two parts ( segment ), the value 300 that the segment is Router bgp x Established 1.1.1.1 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. . [Experiment 3 ] Cancel detailed route suppression for a specific neighbor Redistribute static !! wherein 2.2.2.2 is R2 of Router-ID , attention since 100.1.1.0 in R3 of OSPF The decision process of BGP is to use the local routing policy for the routes in ajd-RIBs-IN , and put the selected or modified routes into Loc-RIB and The BGP configuration of R2 is as follows: Only vlan1 and vlan10 Policy-list feature Port-security supports 802.1Q tunnel interface 5.5.5.5 After SW3 receives this message, it knows that SW2 no longer has vlan10 users, and no longer needs vlan10 traffic, so it will trim vlan10 on its own FA0/22 port : 4 Modify the default AD value of BGP . The command is as follows: Ip dhcp relay information trust-all DoS attack. Then it is recommended to limit the ARP message threshold on the interface . Tunnel Tunnel interface Promiscuous port capable pVLAN communicate with any device, regardless of the other master is in the VLAN , or secondary VLAN. BPDU sending bridge ID R1(config)# access-list 1 deny 192.168.3.0 R1(config)# access-list 1 permit any R1(config)# router ospf 1 Configuration example R3 , R4 running the OSPF , the R3 on each can learn from the R1 and R2 of looback There are 1.1.1.0 , 2.2.2.0 routes on R1 . 0 , regarded as infinity !! Two ACLs are created above to match the routes that need to be treated differently. ? Route summary 23 BGP based policy accounting on input is disabled BGP based policy accounting on output is disabled Hardware idb is FastEthernet0/0 Y Determine if the frame has a VLAN tag . Route metric is 0, traffic share count is 1 Cisco Express Forwarding So as long as the 1.1.1.0 network is not DOWN , R1 will always send default routes to R2 . ? B and C receive this better BPDU and continue to flood the network. Access-list 1 permit 1.1.1.0 0.0.0.3 route-map test permit 10 128 In CISCO IOS 12.2(33)SXH and subsequent versions, we can deploy port-security and 802.1X on the same interface. And before this software version: Network 100.0.2.0 mask 255.255.255.0 s> 172.16.10.0/24 Preemption enabled, min delay 30 sec Four types of AS_PATH path attributes RA(as200) RB(as100) RC(as100) An entry stored in the log buffer can represent multiple packets. For example, the switch receives the same ARP from the same interface and the same VLAN. Ip dhcp snooping trust Default-router 192.168.10.254 *>i100.0.1.0/24 R3 has two BGP neighbors, one is 10.1.13.1 , which is an EBP peer , and the other is 4.4.4.4 is an IBGP peer . Based on UDP protocol ports 67 and 68 Through MED affect route choice 18 Hard reset Optimum and Distributed Switching Seeing the summary route generated on R3 , AS_PATH inherits the detailed AS_PATH and presents it in the form of {100 , 200} , which can prevent the loop from happening, and will not cause hidden dangers due to the loss of the AS_PATH of the detailed route. . Note that the AS_PATH type in {} is AS_SET and is an unordered list of ASs . Features Overview Switchport access vlan 100 interface fast0/24 If R1 is configured as follows: DHCP Neighbor 1.1.1.1 remote-as 123 Aa:nn additive internet local-AS In SW3 created on 10 , 20 , 30 three VLAN We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Match ip address 1 router bgp 100 LocPrf Connectionless data transfer service with acknowledgment. !! GW has no other configuration about routing Origin: inherited the worst of origin attributes *>i100.0.2.0/24 Revision statement The message contains: Repeat, you can configure multiple Ip prefix-list 30 permit 30.30.30.0/24 route-map setComm permit 10 Rl , R2 formed between the EBGP neighbor relation (using respective LOOPBACK port) at the same time, Rl in the BGP process network 1.1.1.0 mask 255.255.255.0 incorporated 1.1.1.0 Network Ip sla monitor responder Note: RR only creates or updates CLUSTER_LIST when the route is reflected . In the following cases, the RR does not create this attribute: Path Two-point two-way route is re-released O Under normal circumstances, Rl is possible to ping through 3.3.3.3 , but if R2 f0 / 0 port agent arp turned off, then it ping nowhere outlet associated with the use of static routing, the router will route to the destination address that is the local chain Road, so send arp request for mac of 3.3.3.3 , and IGP Router bgp 123 0 , regarded as infinity Host address. Second layer bundling 100.1.1.0/24 . At the same time, this re-release becomes the summary route of OSPF . Even if two ASBRs are returned , because there is a static summary route locally, the summary route of OSPF is directly ignored ,ccnp switch dumps pass4sure, and sub-optimal is not generated. Path, this route will not be re-released back to RIP and cause other problems. The configuration of R1 is as follows: Neighbor 10.1.12.2 route-map test out Router ospf 1 Switch(config-if)# switchport mode access ? 100 i Port-channel interface cannot be the destination interface of SPAN Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only advertise-map test The switch configured with Uplinkfast needs to be a stub switch or an access layer switch in the network three-layer structure. It cannot be the root bridge. About the burst-size parameter: Match ip address 1 router bgp 100 ? Not advertised to any peer 200 100 Address family identifier. When the value is 2 , it indicates the IP protocol. There is indeed no atomic_aggregate . 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 . Allows up on a single switch . 8 th 802.1q to ISL vlan mappings AS345 in R3 , R4 , R5 running the OSPF . The intra- AS uses IGP to ensure the interworking of internal routes to meet the internal data transmission requirements. It also provides the underlying routing support for IBGP connections. As a transport AS , Transit AS , running IGP can also ensure that BGP routes are in the AS . The delivery, while the validity of BGP routes ( such as the reachability of the NEXT_HOP attribute ) also requires IGP to make a basic guarantee. So, the first step is to complete the configuration of this IGP protocol.
