By modifying LOCAL_PREF to affect the flow properties *>i100.0.2.0/24 Neighbor 1.1.1.1 route-reflector-client The switch receives the DHCP request , which inserts option82 information into the message (of course, you must do the corresponding configuration first). In the inserted information, the remote-ID suboption is the MAC of the switch ; the circuit-ID suboption is received. The interface ID to the DHCP request message . 200 i Tag rewrite with Fa1/0, 10.1.13.3, tags imposed: {} via 10.1.12.2, FastEthernet0/0, 0 dependencies We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows summary: Of course, the link type of the interface can be modified by commands. In interface mode: spanning-tree link-type ? In the past, switching was hardware-based forwarding, and routing was software-based forwarding, so the campus network used more switching networks. This can indeed avoid the suboptimal path problem, but it leaves a hidden danger: !! Match the exit of the packet When ISP1 is down, the interface of GW connected to ISP1 is DOWN , and the traffic of PC access 100 is automatically switched to ISP2. 200 i Show run int | include bia can see all the MAC , the first MAC will be used by the spanning tree, which is the CPU 's MAC . Next is the MAC of each Ethernet interface . 00:00:54 Set interface specifies how to send such a packet set ip default next-hop specifies the next hop to be forwarded set ip next-hop specifies the next hop to forward Route-map nat3 permit 10 match ip address 2 match interface serial0/1 FastEthernet0/0 Bgp fast-external-fallover Knowledge review Router ospf 1 *>i 100 i Router (config) #server dhcp turn on DHCP services. By default, the Cisco IOS DHCP server and relay agent features are enabled on your router R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. R2#show cef interface f0/0 FastEthernet0/0 is up (if_number 4) Vlans in spanning tree forwarding state and not pruned The configuration of R2 is as follows: Topology change mechanism (detection) ? Match abd , abcd , abccd , abcccd, etc. *end* Method three: default-information originate Ip address 10.1.13.3 255.255.255.0 Interface vlan 10 Id 5.5.5.5 Port-Security is turned off by default SW2 and SW3 are similar situations; note that at this point we are not allowed to do any static configuration of the allowed vlan configuration on the trunk port. In order to verify this rule, we first maintain the basic BGP configuration. Introduce 100.0 by using network on R1 When both the primary and secondary addresses exist, RIP will use both the primary and secondary addresses as the source to send routing updates. So R1 and R3 will learn the routing update of 2.2.2.0 . But R3 ca n't learn 1.1.1.0 , on the one hand, because R1 sends updates to R3 and is ignored by R3. Host address. Network 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. Vlan 100 Case: Problems in the environment of education and telecommunications dual-export NAT network through PBR FastEthernet0/0 3.3.3.3 1 Advantages and disadvantages If an external route carrying a tag is advertised on R1 and OSPF is redeployed to EIGRP on R2 , then the route is advertised. Field name Router(config-router)# distance AD ip-src wildmask acls R4#sh ip bgp Origin IGP, localpref 100, valid, external, best Community: 100:11 no-export 2.2.2.0, but the update is 2.0.0.0 after the summary MD5 digest : 0x73 0x52 0x60 0xE7 0x4D 0xA5 0xC7 0x4F 0xCA 0x3D 0x6F 0x1D 0x3F 0x23 0x03 0xBB internal Community value (route), then how to write it? If you directly match no-export , it will match with 11.11.11.0 , so you should use the exact-match keyword. If configured on R3 as follows: Paths: (1 available, best #1, table Default-IP-Routing-Table) Flag: 0x820 On this topic, the individual feels that there is no need to study it. It does not make much sense for the research of class-based routing protocols. No matter the actual application or the LAB exam, it is no longer involved, and you are interested in making it yourself. abbreviation Router eigrp 100 Network SW1(config)# interface vlan 10 Protocol vulnerability Lease(sec) Type 100 i Wherein SW1 is as follows: Aggregate-address 192.168.0.0 255.255.0.0 as-set advertise-map adv We know that the data of the VLAN that the switch can support is very large. If PVST+ is enabled , each VLAN has a spanning tree, and no spanning tree must have a separate identifier. If you need to use a MAC , then the MAC address pool. It must be unbearable. The above configuration is only to solve the problem of data direction, but the problem of NAT : Aging Type : Absolute SecureStatic Address Aging : Disabled 100 R2 , R3 , aiming RIP create static routing domain summary route, point null0 , while only these static routes redistributed into OSPF , and indeed can play a sub-optimal paths to avoid the question, but: Ip as-path access-list 2 permit _2$ O 2.2.2.2 [110/65] via 10.1.12.2, 00:05:16, Serial0/0 Neighbor xxxx advertise-map xx exist-map xx Note that at this time, the routing table is used to recursively find the route to 10.1.12.2 , so there must be reachable routes in the routing table. Let the CISCO router ignore the AS-path attribute during its decision making process You can enable this feature by using the spanning-tree loopguard default global configuration command. The switch receives the DHCP request , which inserts option82 information into the message (of course, you must do the corresponding configuration first). In the inserted information, the remote-ID suboption is the MAC of the switch ; the circuit-ID suboption is received. The interface ID to the DHCP request message . We know that in a Layer 2 switching environment, a VLAN is a broadcast domain. Broadcast domains with different VLANs are generally different logical subnets, and they are isolated from each other and cannot communicate with each other. This can isolate broadcasts. effect. However, in actual networks, VLANs often require mutual access. For example, different departments of the same company are divided into different VLANs . If there is data exchange between these departments? Then the Layer 2 switch cannot be implemented,how to master ccnp switch pdf free download, and it needs to use the Layer 3 device.
