Vlan 100 Multilink Multilink-group interface Matching with the detailed route 172.16.32.0/24 , so eventually these two routes will be filtered out, which is inconsistent with our needs. In fact, this is the drawback of using a standard ACL to match the route, you can only match the network number of the route, and can not further match the prefix of the route. Ip rip trigger All VLANs SW1(config-if)# glbp 1 load-balancing host-dependent !! The same PC (source MAC ) is assigned to a fixed gateway virtual MAC Select the port for the Channel 100 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 configuration of R1 is as follows: Aggregate-address summary address as-set advertise-map The VLAN ID , which is 12 bits long, indicates the VLAN to which the frame belongs . In VRP , the configurable VLAN ID ranges from 1 to 4094 . After the Port-Security feature of an interface is activated, the default maximum number of secure addresses is 1 ,ccnp tshoot ospf, that is, the interface uses its dynamically learned MAC address as a secure address without manually configuring a secure address. This interface is equivalent to being exclusive to the MAC (the device to which it belongs). And the default violation is shutdown Load balancing You can use ^ at the beginning of a range to exclude all characters in the range, or you can use an underscore _ to specify an interval. C 1.1.1.0 is directly connected, Loopback0 2.0.0.0/32 is subnetted, 1 subnets Sw1(config-if)#ip address 172.16.10.1 255.255.255.0 Sw1(config-if)#no shu Address family identifier. When the value is 2 , it indicates the IP protocol. Full IBGP interconnection between route reflectors in the AS We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows R1R2 establishes an IBGP neighbor relationship and maintains two BGP connections. The local interface is used to establish a neighbor relationship with the peer directly connected interface. Fa0/20 Federal configuration and implementation The above command calls the defined policy-list in the route-map ; multiple policy-lists can be called in a route-map . Next we open vtp pruning on SW3 , which is the server of VTP . R3 , R4 , and R5 use OSPF to ensure inter- AS routing interworking, and use loopback to establish BGP neighbors. None The upper digit is the individual/group bit. When its value is 0 , it can be considered that the address is actually the MAC address of the device . When its value is Decision summary Public Therefore than MED , 2 of MED small, 2 is the best path The configuration on R3 is as follows: 200 port-security does not support etherchannel the port-channel interfaces After the MAX_AGE ( 20S ) timer expires, the BPDU stored in Fa0/3 on SW3 ages, the port enters the listening state, and sends and receives BPDUs. Generally seen between switches or between switches and routers and servers 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. None It can still be saved after the up/down phenomenon occurs. After using wr , these sticky secure addresses will be written to start-up config and will not be lost even if the device is rebooted. If the BGP route is learned from other BGP peers , the MED does not carry the MED when it is advertised to the EBGP peer . It is recommended to configure a wild VLAN as Native vlan. Multiple paths have the same RouterID because they are received from the same router. As shown above, R1 , R2 , and R3 run RIP . In the initial situation, R2 will update its routing table to R1 , which assumes that there are three routes 1.0 , When no BPDU is received for a period of time and the lifetime reaches MAX age , the bridge considers that the port is connected. trunk permanent link aggregation mode, forced trunk , send DTP frames Manual summary Complete the basic configuration Ip prefix-list 1 permit 11.11.11.0/24 route-map test deny 10 Match tag matches based on the tag of the route No confirmation mechanism, anyone can initiate an arp request or response If the route learns to an EBGP neighbor, it is reflected to all client and non- client IBGP neighbors. In order to solve the problem of routing, in addition to the route reflector, there is a good solution, which is the federation. Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . Route-map test permit 20 match ip address prefix-list 2 set metric 100 Feature VLAN: Use the show spanning-tree inconsistentports command to view related entries. *Mar 16 17:09:21.858: DHCPD: relay information option exists, but giaddr is zero. Origin IGP, metric 0, localpref 100, valid, external, multipath : ccnp You can see these two routes by viewing the BGP table on R3 . The introduction of Cluster is to provide redundancy in the environment of RR . In conventional clustering design, a plurality of RR is used for one or more client service, these RR are configured the same CLUSTER_IDs , the ID is the 4 -byte IP form identifier default is RR own BGProuterID If two RRs have the same CLUSTER_ID , then they belong to the same cluster. Another very important role of CLUSTER_ID is anti-ring. When a RR receives BGP routing updates, it carries the same ROUTERID as its own .
