Matchlog keyword in this command and the log keyword in the permit or deny ARP access-list Route-map can be used in different commands for specific purposes Ge ge-value The incoming route is passed from the external AS . The NH is the EBGP peer that advertises the route , and the NH will follow the route to pass within the AS without change (unless a policy is made), always pointing to the next AS (advertise the route) the EBGP peer interfaces IP ). MED attributes for routes published to the federation are retained throughout the federation Various types of ports of a Layer 3 switch ORIGINATOR_ID and CLUSTER_LIST RIP also supports tags , but it must be version 2 . Weight We found that both O , O IA or with the FA 's OE2 routes are redistributed into BGP later, these BGP routes Next-hop are they in OSPF the IGP next hop. At the same time, the network segment where the OSPF direct connection port is activated locally will also be injected into BGP . After the injection,ccnp 300-101 syllabus, Next_Hop is the router (BGP update source IP) . So R2 can ping through 3.3.3.3 After receiving the data frame, the MAC sublayer of B submits to the LLC sublayer, and the LLC sublayer determines, according to the DSAP field, the connection to which the data frame belongs. Vlan 10 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. Rl , R2 formed between the EBGP neighbor relation (using respective LOOPBACK port) at the same time, Rl in the BGP process network 1.1.1.0 mask 255.255.255.0 incorporated 1.1.1.0 Network Risk of routing policy configuration loss In order to solve the problem of routing, in addition to the route reflector, there is a good solution, which is the federation. 200 i 201 200 100 So far, we have completed the basic configuration, then can ping the same 100.0.1.1 and 2.1 from R4 ? After the trial , we must get a negative answer. This is because there is no route in AS345 on R1 and R2 , that is, the backhaul route has a problem. In this topology, we can configure the backhaul route on R1 and R2 or Default route to complete the test of the experiment Network 192.168.20.0 0.0.0.255 area 1 Preemption enabled, min delay 30 sec Active is local, weighting 100 Ip summary-address rip xxxx yyyy // Note that this summary does not support CIDR supernet . switchport trunk encapsulation dot1q switchport mode trunk Each cluster contains a reflector and its client The BGP configuration of R2 is as follows: After the summary command is added with the as-set keyword, the generated summary route can inherit some path attributes of the detailed route, thus avoiding some problems. The rules for inheriting detail attributes from as-set are as follows: If R1 starts auto-summary and introduces 10.1.1.0/24 in the way of re-distribution direct connection , the subnet will be automatically summarized to R2. AS_Sequence is well understood. In the case where the above figure does not make any policy, the type of AS_PATH carried by the BGP route delivered to R4 is AS_Sequence . This is an ordered list of AS numbers. When R4 receives the route update, AS_PATH is 300,100 , 1,10,20,30 10.1.23.3, from 10.1.23.3, 00:07:30 ago Note inconsistent with err-diasble difference is, ERR-disable will disable off the entire interface, and inconsistentport is for a particular VLAN 's. Fa0/20 BGP table on R7 : The two exchange modes , both in principle and in terms of fast switching is very similar , such as optimum switching actually uses an optimized cache switching (optimumed switching cache), its speed is higher than usual cache is faster .distributed switching mode needs use Versatile Interface card this hardware card , also known as the VIP card. it will save a copy of their own route cache, so that when it is not necessary to wait for a query using a shared system cache (shared system buffer), whether with respect to the fast switching or optimum In terms of switching , it is faster .
