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. Private-vlan mapping add 101,102 Receiving behavior In the process of double-point bidirectional routing re-release, many problems may occur, such as sub-optimal paths, potential routing loops, etc. This chapter will discuss this model and existing problems in depth. Router bgp 100 Policy-based Routing (PBR) Policy Routing 80 Encapsulation protocol Type of verification: Paths: (2 available, best # 2, table Default-IP-Routing-Table) Flag: 0x820 The configuration of R1 is as follows: 2.2.2.0 Routing Although the next hop is directed to R1 , it does not use the outbound interface to create routing entries. From the experimental phenomenon, it is not matched by the match . Needless to say, 3.3.3.0 , the associated interface is s0/1 . In addition to matching 100 to 106 outside the AS_PATH Port-Security is turned off by default , 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 R3#show ip bgp summary After Port-Security is enabled, related parameters have default configuration. Gratuitous ARP R2#sh ip route Therefore, when the IGP route network into BGP , the MED value inherits the metric value in the IGP protocol. Sw(config)#interface range fa 0/3-4 BGP Speaker from IBGP routes learned whether it's advertised to EBGPpeer depends IGP and BGP synchronization to decide In the IGP , the network command is used to determine which interfaces to send and receive routing updates, and which directly connected networks. Access-list 1 permit 192.168.1.0 NEXT_HOP to 10.1.123.2 , then if C is not on the router to the IP of PVC , will be a problem,ccnp tshoot study guide, so this should be taken into account. Define the network segment associated with the address pool 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 . TCAM is the table that is checked when the routing module or router is used for Layer 3 forwarding. LocPrf The Permit/deny keyword has a different role in different deployment scenarios. Ip community-list example 1 : 2bb4c2a1 Then PC ping 10.1.13.0 , the data goes R1 ; command 3.3.3.3 SA sends the original switch MAC of the frame Example 1 : Using route-map to associate neighbor filtering routes ? Although RIP is running between R1 and R2 , the routes of 1.1.1.0 and 2.2.2.0 are updated with each other , but since R1 is from RIP and his MAC address. Route-map PBR permit 10 match ip address 1 16 EBGP neighbors must be directly connected to establish an EBGP session. but Route-map test permit/deny 20 On R1 , ip route 1.0.0.0 255.0.0.0 null 0 then ip defaut-network 1.0.0.0 , then R2R3 will learn the default route Switch(config)# interface fast0/15 The configured static network path is redistributed into OSPF . In this way, when the intranet user needs to access the Netcom resources, because of the details of the network access, go to OR1 . To access other resources, take the default route to OR2 . Root modifies its own configuration BPDU to advertise the entire switching network about topology changes. Root sets the topology change ( TC flag) for a period of time in the configuration BPDU . This time is equal to the forwarding delay + Max. Age , the default is 35S. BGP neighbor relationship, the addresses are 3.3.3.3 , 4.4.4.4 , and 5.5.5.5 . The OSPF protocol runs in the AS , so that all routers can obtain the LOOPBACK network segment of other routers . On the R3 , BGP routes are advertised on the network segment 30.0 . R4 is the RR and R3 is the RR client . R5 will receive routing updates from 30 segments at the same time from R3 and R4 . How will it be routed? Which routing rule takes effect? First rule 8 does not apply because the two BGP routes NEXT_HOP are equal, both are 3.3.3.3 , not comparable (reaching 3.3.3.
