Local After receiving this poisoning message, B erases 10.4.0.0 from the routing table, but it still exists in the rip database , the status is possible down , the garbage collection time ( Garbage colletion CISCO default 60S ), the route is from B. The database is erased. BVI Bridge-Group Virtual Interface 100 i This address of the neighbor must be IP reachable Show ip bgp summary Neighbor Ip dhcp snooping trust R3 , R4 , and R5 use OSPF to ensure inter- AS routing interworking, and use loopback to establish BGP neighbors. Switch(config)# vlan 20 Regular expression example: By AS_PATH influence route selection If the interface is trunk , set the trunk protocol type Policy-list is only supported in BGP . Other IP routing protocols do not support this feature. Sw(config-vlan)#private-vlan primary Use the sticky MAC address on the port-security interface * i100.0.1.0/24 The above interface loses the portfast and bpdufilter features immediately after receiving the BPDU , and becomes an ordinary spanning-tree interface. R5 release B segment RIP routing, R2 and R3 can learn, at the moment we are in R2 and R3 are on to OSPF to inject RIP routing, assuming that R2 injected first, then the B route will be R1 update to R3 , R3 this When you learn B routing from both RIP and OSPF , then it will: If the result of the search finds an exact match, the data is forwarded according to the returned port number. We look at the above picture, the external detail route 172.16.32.0 – 39.0/24 , and the summary route 32.0/21 are introduced into OSPF by R1 , now End of a string Configure an interface as a passive interface: RIP and OSPF re-release When 10.4.0.0 is hanged , C will immediately send a route poisoning message ( 10.4.0.0 16 hops) and then advertise it; ATOMIC_Aggregate 3.3.3.3 The configuration of R4 is as follows: Unused LocPrf 200 ? Fa0/20 This environment is relatively simple, PC and DHCP server in the same VLAN , I mainly want to confirm that the ordinary switch pair is carried EBGP load balancing is verified. Only when the routes originate from different EBGP neighbors in the same AS and meet the equivalent load balancing, you can configure the maximum-paths x to implement load balancing. For example , the configuration is based on different ASs . The command is also invalid BGP table on R6 : --------------- 192.168.10.1 When the router performs a classless route lookup (by default, ip classless ), it does not pay attention to the class of the destination address. It performs the longest match between the destination address and all known routes bit by bit . * i Route-map cisco permit 20 match ip address 2 set metric 20 The second command is to adjust the AD value for external routes, inter-area or intra-area routes . BPDU format and operation CFI Timeout Configure abort timeout interval * i If it is injected through network or re-release, the IGP next hop of the prefix will be the next-hop of BGP before injection. The election of the Root Bridge will not be said. When R2 LocPrf A the LLC sublayer own data to be transmitted is encapsulated, wherein the DSAP byte is filled B return to the SAP , the SSAP bytes are filled to their open the SAP , and then sent to MAC sublayer. Here to add a sentence, since attention to traffic, we must pay attention to the round trip of traffic, in general, we want 1.1.1.0 access 3.3.3.0 traffic to go ADC , then round-trip traffic generally requires a consistent path. That 3.3.3.0 to 1.1.1.0 data to a CDA , so to further D on the update to the C of 1.1.1.0 route of metric plus 1 jump. RIP is re-released into OSPF Neighbor maximum-prefix xx restart 2 The client ( D ) passed to it by the RR is not passed to the non- client (E) 3.3.3.3 Fast switching is superior to process switching, it uses a route cache ( route cache ) for storing information about a stream of data (Flow) specific information , Then just republish this static summary route into OSPF . In this way , the routers in OSPF can reach through this summary route. Protected port Non- Route-map ( automatic ) mode : You can also use the show ip dhcp bingding to capture the client-identifier of the client on the server. Management VLAN in a Layer 3 switch environment In the above figure, if both ends of the PC belong to vlan10d , if the fa0/23 port of SW1 will vlan10remove off, then the PC will definitely not be able to communicate. DMZ-Link Bw can only configure single-hop EBGP neighbors on this router. 200 i Using the previous two commands, the aging time does not affect the static address entries that are statically configured. Of course, the sticky entries are not affected. These entries are never aging, but if you match the above For a command, the manually configured security address entry is also limited by the aging time. The configuration on R3 is as follows parameter or O E2 1.1.1.0 [110/20] via 10.1.23.2, 00:06:40, Serial0/0 Async Async interface Native vlan Switch(config-if)# switchport mode dynamic {auto | desirable} When a router connects through a multi-access medium such as Ethernet, a dynamic mechanism is needed to discover each other, such as ARP . ARP can map Layer 2 addresses to IP . If it is a frame relay multipoint link, the adjacency relationship can be learned by using an address resolution protocol, a mapping table, and the like. Route-map first acquaintance Neighbor 10.1.23.3 local-as 201 [no-prepend] [replace-as] [dual-as] R4#sh ip bgp Default behavior: source IP address pair ( src-dst-ip ) Precautions AS_PATH ). This can lead to loops. The solution is to set the AS_PATH keyword to restore the AS attribute when C publishes the summary route. At this time, the summary route will declare AS_SET at the same time , and AS_SET is an unordered AS list,ccnp route netacad answers, among which AS200 The information so that the B router receives this summary route and finds that the AS_SET has its own AS and therefore ignores the route.
