Route redistribution is directed. The routing information of the A routing domain is injected into the B routing domain. We need to configure it in the process of the B routing protocol. For example, to redistribute other routing protocols to RIP ,ccnp switch quick reference guide, then configure. As follows (republishing to other routing protocols is similar): A BGP neighbor has an impact only on the router. It can be understood as a weight value. The larger the priority, the higher. The value is in the range 0-65535 . PAgP mode: : 000a.8a07.8280 [Experiment 7 ] There are subnet routes (no match); there are default routes Hostname R5 A advertises the detailed route to B , B advertises the detailed route to C and D , and C advertises the summary route. At this time, the summary route will be transmitted to B in addition to being notified to D , and this may cause problems. Therefore, you need to filter the summary route on the IP distribution-list x of neighbor B on C. Otherwise, a routing loop will occur. Router ospf 1 The message will not be passed to any BGP neighbors. The range is 0-65535 . ! Preferred routes sent by EBGP neighbors (relative to IBGP neighbors), preferred federation EBGP in federated EBGP and IBGP In PVST+ , a VLAN has a spanning tree. On each switch, a unique identifier is required for each spanning tree, that is, the network. How to perform non-equivalent load balancing? In this figure, the bandwidth of the uplink interface of R2 is actually not equal. If you do the following configuration on R2 : No-advertise no-export Configure all interfaces as passive and manually activate specific interfaces: or: 46-1500 bytes; set mtu xxxx under the interface , which means this, and generally does not allow Port Configuration Example The above match statement is used to match the summary route. SW1(config-if)# switchport nonegotiate FastEthernet1/0 BGP table version is 10, local router ID is 2.2.2.2 This comprehensive thinking question helps you sort through several solutions: In the one local BGP routes advertised to EBGP the Peer time, whether they carry MED values , need to be determined under the following conditions ( not EBGP Switch(config-if)# switchport port-security aging static 5.5.5.5 ( metric 2 ) from 5.5.5.5 (5.5.5.5) Interface fast0/0 Troubleshooting 33 You can enable this feature by using the spanning-tree loopguard default global configuration command. Note that if you attempt this time SW2 on F0 / 2 interface priority piecemeal, and it is useless, because the port is looking at the sender ID . So if on SW1 , the port priority of F0/2 is reduced. Then on SW2 , F0/2 will win as the root port. Aggregate-address summary address summary-only as-set Route redistribution The cache extracts the destination interface , destination MAC address, etc. , which greatly speeds up packet forwarding. Database , this database is DHCP Snooping listens for DHCP information recorded after the interaction, inside contains the client's IP , the MAC , belongs to VLAN -related information, etc., and this information, just as ARP 's legality verification. The default priority is 32768, and the range is 0-65535 . The first 4 bits are the priority . The last 8 bits are used as the system id . The smaller the better , the multiple of 4096 . VLSM support VLAN Interface Advertised to update-groups: 1 The switch forwards the DHCP packets carrying the Option 82 information to the DHCP server. Set aging time As mentioned earlier, DAI performs ARP legality verification by means of the DHCP snooping binding database . Another basis for legality verification is the manually configured ARP ACL . AS345 in R3 , R4 , R5 running the OSPF . The intra- AS uses IGP to ensure the interworking of internal routes to meet the internal data transmission requirements. It also provides the underlying routing support for IBGP connections. As a transport AS , Transit AS , running IGP can also ensure that BGP routes are in the AS . The delivery, while the validity of BGP routes ( such as the reachability of the NEXT_HOP attribute ) also requires IGP to make a basic guarantee. So, the first step is to complete the configuration of this IGP protocol.
