Content Addressable Memory Table content addressable memory BGP table Distribute-list OSPF and IBGP route re-release A route-map containing a set of match statements can be defined in advance as a list of commands called a policy-list. Match interface s 0/0 If R1 starts auto-summary and introduces 10.1.1.0/24 in the way of re-distribution direct connection , the subnet will be automatically summarized to R2. Ip route 172.16.3.0 255.255.255.0 172.16.12.3 By default, BGP does not allow static default routes to be injected when static is re-released ; unless it is in the BGP process at the same time default-information originate Experiment 1 Switch(config-if)# ip address 192.168.255.254 255.255.255.0 S 172.16.0.0/16 [1/0] via 172.16.3.0 S 172.16.3.0/24 [1/0] via 172.16.23.3 LocPrf Ip route 172.16.1.0 255.255.255.224 192.168.12.1 Ip prefix-list FILTER deny 1.1.1.0/24 ip prefix-list FILTER permit Originator_ID Cluster_list Weight First ensure that R1 , R3 to 10.1.1.0 are routed,ccnp 300-115 blueprint, and test on R2 : In the above figure, R1 and R3 will update routes 1.1.1.0 and 11.11.11.0 to R2 . Of course, by default, R2 is definitely the preferred EIGRP. The route obtained by the BGP speaker from IBGP is not advertised to its IBGP neighbors (avoiding loops and splitting horizontally; except for the case of route RR ) FastEthernet0/0 Exchange network security Ip dhcp pool BIND ? Transparent mode VTP configuration revision number is always 0 AS does not compare the MED values. In other words, for multiple paths, the MED is compared only if the first AS in AS_SEQUENCE is the same ; any leading AS_CONFED_SEQUENCE will be ignored. MED only affects traffic between directly connected autonomous systems, and does not pass across ASs. 1,10 IP address, and then take the destination IP address to look up in its own routing table. After finding the "best match" entry, the packet is forwarded according to the outbound interface or next hop IP indicated by the routing entry . This is the IP route. ( IP routing ) . And each router maintains a routing table locally. Network Router ospf 1 R2#sh cef interface s0/0 policy-statistics input Serial0/0 is up (if_number 4) Since the flash space is very limited, it is recommended to store the file on the TFTP server. When deploying on a TFTP server, be careful to first create an empty file to correspond to the URL in the configuration command . This file is used for dhcp snooping bingding database writes (depending on the device). 6 Vlans in spanning tree forwarding state and not pruned This is the general case, of course, there are two situations, it depends on the specific environment and the specific routing protocol. 100 Metric At the same time, R4 also received the 100.0 route introduced by R2 , but it was not passed to R3 . This is the principle of horizontal splitting of IBGP : " BGP routers will not pass IBGP to him and pass it to other IBGP neighbors." If the static keyword is used , it means that the ARP ACLs enable the implicit deny any mechanism. That is, if ARP packets and ARP ACLs are used. 4.3.3 Certification 36 Active is local 3.1 Overview 20 Redirection enabled ! ! Automatic generation Dhcp-snooping The solution is as follows: 1. On the R3 , declare the directly connected network segment of 10.1.13.0 into OSPF , and R5 is the same; 2. Modify it on R3 . To summarize on R3 , use aggregate-address summary-only as-set , then the BGP table on R3 : Neighbor table The parameters and capability features are negotiated successfully. You start to send the Keepalive package and wait for the other party's State BGP current callback state is basically opensent, etc., admin indicates that the neighbor is managed-type shutdown , when [Experiment 3 ] No main class network; there is a default route, take the default route If the number exceeds xx , disconnect the BGP connection with the neighbor and reconnect after 2 minutes. It can only be mapped to the ethernet of vlan Static route associated with the outbound interface R1 , R2 running OSPF , R2 learned 1.1.1.0/24 the OSPF routing ( Metric to 65 ) in R2 on the BGP routing process in the network 1.1.1.0 mask 255.255.255.0 Still looking at the picture, if the middle network is not a broadcast multi-access network, but a frame relay network, then it should be noted that the route received by C , Keepalive package. Port ID ( 2 bytes) = Port Priority (1 byte ) + Port ID (1 byte ) OSPF routes take effect, and only 1.1.1.0 routes survive. The source of continuous routing is direct routing, or RIP . / / Is to shield the route from the RIP re-released in addition to 1.1.1.0 , and re-release the local direct connection The GW configuration is as follows: IP address 200 i Weight AS_SEQUENCE exactly the same, except that the list of AS numbers belong to the local Federation AS Load balancing 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 : Because when actually deployed, SVI mouth may be more, go to if one of the no passive-interface to configure the amount may be relatively large, so you can choose to passive-interface defaut all interfaces of all passive off, and then a single interface to no passive -interface . Set ip next-hop verify-availability 10.1.1.2 10 track 1 Establish BGP neighbors Marker : for detecting BGP loss of synchronization between peers, the message authentication, and in the case of supporting an authentication function if the message type is open or open message does not contain authentication message flag field is set to all 1 , 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 Switch(config-if)# no shutdown Routing entry for 192.168.1.0/24 Sw1(config)#interface port-channel 1 // Enter port-channel group 1 to configure IP Experiment 3 OSPF 's neighbor command is not the same as EIGRP . After testing, in the Ethernet environment, directly refer to the neighbor , and still send multicast hello. 3.3.3.3 * i100.0.2.0/24 learner The certificate contains the password information when it is verified using plain text. Neighbor 10.1.23.2 remote-as 200 neighbor 10.1.23.2 route-map test in Destination address: The address of the host or network. R1 Interface The configuration of R4 is as follows: Add the following configuration on R3 : 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 It is used to preferentially send packets with high priority when the switch is blocked. Aging Type : Absolute SecureStatic Address Aging : Disabled Bgp confederation identifier 345 bgp confederation peers 64513 neighbor 3.3.3.3 remote-as 64512 At this time , OSPF routes are re-advertised to BGP on R11 , so that R12 can learn. After R12 learns the route, it finds that BGP attributes (including AS_PATH ) are lost. Because OSPF redistributed into BGP , the default does not automatically tag values are copied into the AS_PATH , the need to R11 on Network 192.168.24.2 0.0.0.0 area 0 In the above figure, two routers , R1 and R2 , exchange information with each other through RIP . However, since RIPv2 sends routing updates and related messages based on multicast, once two routers activate RIP on the interface , the PC will have to consume resources to process these multicast messages that it does not need.
