802.1 D Sw(config)#vlan 202 This way the routing table: Neighbor maximum-prefix 300 90% warning-only As a result, R6 will receive summary routes from R4 and R5 , respectively : 172.16.0.0/16 In 802.1q the native vlan is untagged, using Dot1q switches all unmarked frame is forwarded to the native vlan in the ISL on all data frames, including native vlan encapsulation, so if the package is not received The data frame will be discarded (the ISL does not have the concept of a native VLAN ). The default native vlan is vlan 1 Host 192.168.1.111 255.255.255.0 Match tag 10 For link state routing protocols such as OSPF In RIPv1 based on the increase Verify again, instead of detailed routing, use a summary route of ip route 10.0.0.0 255.0.0.0 , the next hop is R3 , the effect is the same as above, also take R3 . Therefore, as long as it is not the default route, as long as there is such a matching route in the routing table, the route is taken preferentially, and the route-map is taken without the route . Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd !! Two ACLs are created above to match the routes that need to be treated differently. Note that there must be three layers between the DHCP server and the trunk interface. Because the unicast packet is relayed, the source address is the trunk interface configured with ip helper-address . Therefore, when the DHCP server returns the packet, the destination IP address of the packet. This is the interface IP of the interface configured with ip helper-address . Define the network segment associated with the address pool 1.1.1.1 (metric 129) from 4.4.4.4 (4.4.4.4) The configuration of R5 is as follows: CISCO Note: The DHCP option-82 feature is supported only when DHCP snooping is globally enabled and on the VLANs to which subscriber devices using this feature are assigned. Passive-interface defualt Clear ip bgp * Network 100.0.1.0 mask 255.255.255.0 , By the spanning tree protocol in a particular port logically Block , in order to achieve redundant physical environment, and the upper floor and preventing the loops byte Routing? 6 R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. Where min ( holdtime ) is the minimum value of holdtime between two BGP neighbors. 802.1q Trunks can be statically configured or negotiated through DTP . OSPF TAG Overview This entry will be entered into the routing table as a direct network (see below) Path Paths: (1 available, best #1, table Default-IP-Routing-Table) Flag: 0x820 1 Example 1 : Example of multiplication characters: To 100 end of the AS_PATH , which is the route originated in 100AS route The configuration of R3 is as follows: 802.3 does not recognize the upper layer protocol and must be used with a dedicated LAN ( such as IPX) . For example, in R3 viewed on R5 sent me 6.6.6.0 of this OSPF external routes, you can see the tag field is 600 (automatically inherit the AS_PATH ) And this time, R3 the OSPF redistributed into BGP , the default is not automatically restored AS_PATH attribute, so you need: Ip address 10.1.34.3 255.255.255.0 And the preferred order is: i > e > ? 5.5.5.5 Vlans allowed on trunk RR transmitting the AS ( Transit the AS ) is divided into small units,ccnp route exam questions and answers pdf, i.e. reflection clusters CODE : 82 Represents a range. Matches only one of the characters contained in the range. New link Link1 between A and Root Report routing information. R2(config)# access-list 1 deny 192.168.3.0 R2(config)# access-list 1 permit any R2(config)# router ospf 1 Switch(config-if)# no shutdown The buddy first introduced the above network environment. This Nima is a fairly classic case. OR1 and OR2 are the egress routers of the network, which are respectively connected to the egress lines of Netcom and telecommunications. PAT is implemented on both egress routers , so that intranet users can access the extranet. In addition to OR1 , *> The Layer 2 switch searches for VLAN configuration information based on the destination MAC address and VLAN ID of the frame, and determines from which port the frame is sent out. Set ip next-hop 10.1.1.2 10.2.2.2 set ip next-hop verify-availability interface fast 1/0 Routing Policy R3 receives two routes, respectively carrying the community attribute as above. Now, we only want to delete the no-export attribute of the 11 route . Then 1 , 2 compare first, 1 is preferred (because 1 has a smaller MED ); since 1 and 3 are in the same AS , so again CAM table ( 20s time), start to enter the listening state Ip address 4.4.4.4 255.255.255.0 The difference between set ip next-hop and set ip default next-hop is relatively simple, it is not resolved here. Metric -------------- When the router is in the boot mode and the software is upgraded, the ip routing is also closed, so the command will be used when necessary. Routing Policy R2 's F0/0 port is configured with proxy ARP , 3.3.3.0 network R2 itself is reachable, so R2 will respond to this ARP request with its own F0/0 port MAC . In fact, this is an ARP spoofing behavior: ) Route 3 : AS_PATH : 500 Network consolidation (same protocol or different protocols) FastEthernet FastEthernet IEEE 802.3 Automatic summary We will find that when the topology changes, the TCN will be generated . However, in some cases, the transition flooding of the TCN may have an unnecessary impact on the network . The interface connected to the PC terminal device on the access layer switch is set to portfast network can be optimized to a certain extent, prevent the PC interface of the switch due to switch updown and excessive the TCN .
