BGP supports MD5 authentication. To enable MD5 authentication on the TCP connection between BGP peers , use the following command: DAI configuration command R1 and R2 run IBGP , use LOOPBACK as the update source, and refer to neighbors . R2 and R3 are EBGP relationships. R3 announces 3.3.3.0/24 into BGP , and configures next-hop-self for R1 on R2 . Unicast Update After the summary command is added with the as-set keyword, the generated summary route can inherit some path attributes of the detailed route, thus avoiding some problems. The rules for inheriting detail attributes from as-set are as follows: Set default interface specifies how to send such a packet Acl-match matchlog —Logs packets based on the DAI ACL configuration. If you specify the 0.0.0.0 . Active is 10.1.1.252 (primary), weighting 100 (expires in 7.028 sec) Arp replies sent: 1 Revision record Interface vlan 10 SW1#show ip dhcp snooping binding As mentioned above, a route is allowed to carry multiple community values ​​to form a community list. If you want to delete one or several community values, for example, Three-layer bundle 1.1.1.1 (metric 129) from 4.4.4.4 (4.4.4.4) If you want 11 routes of 100: 11 and no-export two community values are deleted, modified del This community-list to: 0 ? Match ip address 1 set metric 20 IP routing troubleshootingSolution: Use distribution lists to circumvent suboptimal path problems 101 / / Set the interface mode to Trunk mode 1,10,20,30 The ethernet , fast ethernet , and serial interfaces of the Cisco 1600 , 1700 , 2500 , and 2600 series routers use fast switching by default . Revision record Ip address 10.1.13.1 255.255.255.0 Network Verify BGP routing rules and test BGP related policy tools. Configuration Example R1 and R2 run RIP ; R2 and R3 establish OSPF neighbor relationships. In the initialization case, there are four entries in the routing table of R2 , as shown in the figure above, and there are only two entries in the routing table of R1 , that is, two direct links. So now, we do the re-release action on R2 , and redistribute the OSPF route to RIP , then the configuration is as follows: Option 82 sub-option 2 : Remote ID , which is generally the MAC of the access layer switch that inserts the option 82 information . Match x1 match x2 , x3 set Y Port-Security deployment considerations Switchport access vlan 100 interface fast0/24 OR2 , SW1 , and SW2 run OSPF , and OR2 acts as the egress router of the telecommunications, injecting a default route into the OSPF domain. OR1 will be local The route to the LOOPBACK interface. Use 224.0.0.9 Fa0/20 If R1 turns off auto-summary and network 1.1.1.0 , the declaration is unsuccessful because there is no mask for class declaration. After a few seconds, D receive this the BPDU , Block out port P1 Distance bgp xyz //x is the EBGP route, y is the IBGP route, and z is the BGP route announced by the local network . 0 100 i Metric PAgP mode: Route-map OSPF3to2 permit 20 match tag 20 FastEthernet1/0 Route-map first acquaintance Bridge ID in the MAC , is the backplane of the switch MAC , the port ID in the MAC switch port MAC , all the view switch mac available 8 *>i1.1.1.0/24 If the static route configured by the outbound interface is configured,ccnp switch hands on skills exam, the router considers the destination network segment as a local direct connection . Therefore , when the RIP is in the network , it will be announced. s> 172.16.2.0/24 Input conditions: length < ge-value < le-value <= 32 / / Use the federal member AS number to establish BGP Distance vector routing protocol 28 Show mac address-table clear mac address-table Solution: Use distribution lists to circumvent suboptimal path problems 101 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 Distribute-list 1 in Reference 39 UplinkFast Neighbor xxx password xxx Access-list 2 permit 10.1.2.0 route-map cisco permit 10 Then the received route becomes 10.1.20.0/24 and the mask is correct . As shown above, the position of the line is 16+4=20 , so we get the summary address: 192.168.0.0/20 , which is the most accurate summary address. 802.3 does not recognize the upper layer protocol and must be used with a dedicated LAN ( such as IPX) . When a route oscillates (continuously fails, recovers), it is assigned a penalty value. The more the swing, the larger the penalty value and the constant accumulation. Next Hop Local updater ID is 0.0.0.0 (no valid interface found) Reissued by an early agreement like EGP Route tag: A tag that distinguishes between internal routing protocol routes and external routing protocol routes. Ip address 10.1.12.2 255.255.255.0 EIGRP 's passive-interface neither sends nor receives routing updates, nor does it send HELLO packets. The smaller the RID of a BGP neighbor is, the higher the priority is. Verify the value of experiment 1 ORIGINATOR_ID R2 ignores R1 update sent over, because the "active examination", from R1 sent from the RIP updates and R2 of S0 / 0 Kou not in the same subnet, so R2 ignored R1 incoming routing updates. At this time, just validate-update-source under the RIP process of R2 . Match ip address 1 set tag 10 Netflow switching VLAN works on the second layer of the OSI reference model Redistribute rip subnets tag 1111 If the MAC address is not in the security address entry and the security address has reached the maximum number, the illegal data will be discarded only. The legal data will be forwarded as usual without triggering a syslog message. The " Security Violation Count " under the interface is not. Will add 1 . If it is restrict , the illegal data is discarded, and a syslog message is triggered at the same time . Furthermore, the Security Violation Count is incremented by 1 , and the legal data is forwarded as usual.
