Mapping is only valid locally Route-map COST1 permit 10 match ip address prefix-list 100 SW3#sh int tru Sw1(config-if-range)#no switchport // Configure the L3 interface *>i BGP comes in 1 and other routes are 20 , and the metric between OSPF remains unchanged. access-list 1 deny 172.16.32.0 0.0.0.255 In fact, this is more a problem, because such an approach, in fact, the last 8 bit group no matter what, will be live match, he is even more imprecise. Y In the above output, the metric part of the red bold is the IGP metric that reaches the NEXT_HOP attribute address locally . We find that from R3 and R5 , the metric is 2 , then if we connect R4 to the interface of R3 , that is, F0/ 0 port OSPF 802.3 does not recognize the upper layer protocol and must be used with a dedicated LAN ( such as IPX) . 3.3.3.3 Route-map nat1 permit 10 match ip address 1 match interface serial0/0 EIGRP summary routing Conditional delivery of default routes To verify which outbound interface is used for a particular traffic in destination-based load balancing, use R4#sh ip ro 192.168.1.0 MAC address. Load balancing mode 16 Address Experiment 2 Routing table When no port-secuirty mac-address sticiky is typed at this time , all sticky secure address entries become dynamic secure address entries ( SecureDynamic ) Write-delay Configure delay timer for writes to URL R1 and R2 are private partners. Some special traffic may need to be protected. Therefore , the dedicated line between R1 and R2 is added. If you want to ensure the traffic between 1.1.1.0 and 2.2.2.0 is exchanged through the leased line (running) the RIP ) away, when the green DOWN , only to take the following multi-access network. PAgP mode: R2(config)# router eigrp 100 802.1q Experimental example: Called when republishing BGP is designed to AS transfer routes between, so it is actually a hop AS . Le le-value After receiving the packet check, R2 finds that this is the IP of the same subnet as the interface that accepts the update package , so accept this update. Therefore, this test, although the interface masks on both sides are different, but can accept each other's updates, and can also ping between 1.1.1.1 and 2.2.2.2 . Bgp bestpath as−path ignore This command, if configured, skips this rule The Protected port feature cannot be configured across switches: !! GW has no other configuration about routing R2#sh ip b 100.100.100.0 Lease(sec) Type Router ospf 1 LocPrf Interface f0/1 R2#show adjacency detail 10.1.34.3 from 10.1.34.3 (3.3.3.3) 8 Activate the portfast feature for a specific interface IP Routing Overview 5 The AS_SEQUENCE attribute will be passed to R7 along with the route 11.11.11.0 , so the packet is captured on R7 . The attribute of AS_CONFED_SEQENCE is not visible in the route of 11.11.11.0 , so the external AS treats the federation as a single AS (outside I don't know the situation inside the federation) Priority 120 (configured) Neighbor 10.1.13.1 remote-as 100 Local origin ARP packets are detected and released directly. For untrusted interfaces, ARP packet after receiving back checks only legitimate ARP packets can not be released, if the emergence of illegal ARP packets, it will be log , while discarding. 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. By default, the RIP running on the CISCO router sends v1 and receives v1 v2 . If the display is declared as v1 ( use the version in the RIP process) Next Hop OSPF and EIGRP re-release We use ip ospf cost 100 on the F0/0 port of R4 to increase the interface cost , so the result is as follows: The BGP configuration of R2 is as follows: Set ip next-hop verify-availability [ next-hop-address sequence track object ] When both DSAP and SSAP take a specific value of 0xff , the 802.3 frame becomes a Netware-ETHERNET frame to carry NetWare. Redistribute ospf 1 match external 1 external 2 VTP operation The switch sends data frames according to the discovered outbound interface. 0 , regarded as infinity Think carefully about what will be wrong, in fact access-list 1 deny 172.16.32.0 is a summary route 172.16. 32.0/21 The update is sent. At this time, both parties have their own routes, but 1.1.1.1 cannot ping with 2.2.2.2 . BGP routing table entry for 172.16.0.0/16, version 3 Both SW1 and SW2 can learn, and three-year-olds can do it. Default route 108 *> 100.0.1.0/24 Router(config-dhcp)#network [network address][subnet mask] Path C 192.168.23.0/24 is directly connected, Serial0/1 5.5.5.5 The physical interfaces belonging to a port-channel must have the same configuration as below. Use set as-path tag to restore, for example, this example on R3 , The traditional STP , which is 802.1D , is that all VLANs share a spanning tree. The advantage of this is that the switch does not use too much resources to calculate multiple spanning trees. However, the defect is that the port is fixed through the block . As a result, traffic on the network only goes to one side, and some links have no traffic at all, which wastes bandwidth. RSTP is designed so that we don't have to rely on the adjustment timer and can make the interface safely transition to the forwarding state. To achieve fast convergence on the interface, RSTP introduces some new concepts: 170 Let 's take a look at the features of BackboneFast : A route-map containing a set of match statements can be defined in advance as a list of commands called a policy-list. 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). Note that, EIGRP the metric is a mixed type, metric. 1 100000 100 255 1500 Parameters specified here, from left to right is the bandwidth, delay, load, reliability, the MTU . It can be flexibly set according to actual needs. After the above configuration is completed, R2 will be in the routing table. Ip prefix-list 1 permit 11.11.11.0/24 route-map test deny 10 * i100.0.2.0/24 Path Ip dhcp relay information trust-all Refcount 6 Configuring a sample RIP environment Complete the basic interface IP configuration . Add the following configuration on R2 : Switch(config)# vtp domain cisco Send Update package IBGP established between neighbors neighbor, in order to ensure the stability of neighbor relations, general use loopback interfaces to establish, because if you use the physical interface, the physical interface failure, neighbor relations DOWN up, and AS inside,ccnp r&s route 300-101, the path may be redundant LOOPBACK routes between neighbors can be obtained through IGP and provide some routing redundancy (when physical lines are also redundant). When establishing a BGP neighbor relationship using the loopback interface , be sure to specify the source IP address to be updated .
