In the BGP table, only one route is preferred, which should be R3 (because R3 's RouterID3.3.3.3 is less than R5 's 5.5.5.5 ) Port-Security configuration steps 2.2.2.2 Via 10.1.13.3, FastEthernet1/0, 0 dependencies The VTP Server and clients synchronize the database with the highest revision number; Test purpose: VLAN information transfer Establish BGP neighbors *> 100.0.1.0/24 By default, only the MED values of BGP routes from the same neighbor AS are compared , that is, if the two routes of the same destination are from different The default native vlan is vlan 1 Public Ip address 192.168.10.254 255.255.255.0 TCN BPDU Overview Ip policy route-map x Timer bgp 0 0 neighbor never goes down Isis Interface FastEthernet0/1 switchport access vlan 10 Local 200 i Topology change mechanism The above command calls the defined policy-list in the route-map ; multiple policy-lists can be called in a route-map . Other configuration Add all R1(config-route-map)# match ip address prefix-list list1 Detailed rules Milne 's packet was sent to Roo because he learned the wrong one. Then the NH of this BGP route is the interface IP of the announcer . EBGP neighbors generally use the other party's direct interface IP to refer to the neighbor . However, if the EBGP neighbor is established by using the LOOPBACK interface , the NH is the update source address of the EBGP neighbor. (Of course, the EBGP neighbor does not use the LOOPBACK interface to establish a neighbor.) basic configuration ! As a result, the directly connected network segments of all devices are also connected. In AS345 , the routes are also available. This is for BGP . We did not pay attention in OSPF declared the R3 's s0 / 0 and R5 is S0 / 0 interface. verification Sw1(config-if-range)#channel-protocol pagp/lacp Sw1(config-if-range)#channel-group 1 mode desirable 2 INDEX This port is the peer switch source port so the ISL frame is up to 1548bytes ( 1518+26+4 ) Network 172.16.10.0 mask 255.255.255.0 BGP routing table entry for 100.100.100.0/24, version 3 Paths: (2 available, best #1, table Default-IP-Routing-Table) Multipath: eBGP None One way is to establish a fully interconnected IBGP Although the network devices are in the same subnet, they belong to different pVlans , and communication between pVlans must be implemented through the default gateway. The above four types are distinguished by the type code in the AS_PATH attribute. For the two federally unique AS_PATH types, please refer to the “Federal” section of this document for details. How do you understand the first two AS_PATHs ? But there is a loop in the second floor environment. 32 bits BGP introducing and transmission routes Note that the main TC while timer is timed on the port, and the BPDU sent by the port will be set by the TC bit , and the BPDU will also be sent out from the root port. RIP and IGRP the passive-interface does not send routing updates, but to accept routing updates In an IP network, Routing is a very, very basic concept. The basic function of the network is to make two in the network Difficulties Case Ip community-list 11 permit 100:11 AS Hops 1 After DHCP snooping is enabled on the switch , the switch uses the DHCP interaction content that is "listened" on the untrust interface to form a table: Port-Security and Sticky MAC Address Address family identifier. When the value is 2 , it indicates the IP protocol. *>i2.2.2.2/32 !

Interface configuration: spanning-tree bpdufilter enable Next is the re-release of EIGRP to OSPF : Exit Therefore, we still need to keep the AS_PATH of its details on the summary route. As for the order of the AS number in the AS_PATH of the reserved detailed route ,ccnp route v2 pdf, it is not important, because we only need the AS number for the purpose of anti-ring. It is. Therefore , the summary route generated by R3 actually carries two AS_PATH types, one is AS_Seq , the value is 300 , the other type is AS_set , contains two AS numbers of {100,200} , and is unordered. So the AS_PATH received on R4 is 300 (100,200} combined . It is worth noting that the AS number in this bracket is only counted as one hop when performing the AS_PATH calculation. For the verification of this point, please see the section on routing rules.
