Sign S 172.16.3.0/24 [1/0] via 172.16.23.3 Data forwarding mode Paths: (2 available, best #2, table Default-IP-Routing-Table) Not advertised to any peer Ip dhcp snooping The length of the AS_PATH is to influence the path selection. It is not recommended in the actual environment. Use the err-disable command to modify the duration of the err-diasable state. The default is 300S. Message interaction process Neighbor 4.4.4.4 remote-as 345 Let's take a look at the role of these well-known values ​​of community : Switch(config)# vlan dot1q tag native AS_PATH type 2 : AS_SEQENCE detailed When ISP1 when down, and GW connected ISP1 interface not DOWN (such as closing ISP1 the CDP ), since the GW lost ISP1 of CDP Neighbor 10.1.13.3 remote-as 345 neighbor 10.1.13.3 route-map test out no auto-summary For example, in this example, we want to inject, the metrics of the two routes 192.168.1.0 and 192.168.2.0 become 2 hops, and 3.0 becomes R1(config)# access-list 1 deny 172.16.32.0 R1(config)# access-list 1 permit any So far, we have completed the basic configuration,ccnp route 300-101 dumps pdf, 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 When a BGP router sends a route update to its EBGP neighbor, it cannot carry the LP attribute. The LP value of the EBGP route received by the peer is empty. Atomic_Aggregate is a recognized self-determination attribute; Aggregator is optional. Each AS has an identification number ranging from 1 to 65535 , of which 64512 to 65535 are reserved for private use. !! Take the main class route Compatibility 37 Router bgp 123 Y 10.1.13.3 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 . R1 , R2 , and R3 run RIP , and 1.1.1.0/24 on R1 is not directly announced. On R2 : Therefore than MED , 2 of MED small, 2 is the best path BGP routing table entry for 100.100.100.0/24, version 3 Paths: (2 available, best #1, table Default-IP-Routing-Table) Multipath: eBGP The VTP protocol sends a VTP notification every 5 minutes or when there is a change; R1 Port role: After the DAI is enabled, if the downlink PC sends a large number of invalid ARPs in a period of time , it may cause a large loss of switch performance, that is, Router#show ip route Cisco Private Strange phenomenon: In the BGP table of R5 , there are only two routes advertised by R2 , and the 100.0 route from R3 is not passed to R5 via R4 . In other words, we expect that AS345 will have redundancy to 100.0 network. Remaining path (through R1 , 3 The concept of traditional IP routing Let us review: When the router receives an IP packet, check the IP header of the packet, and take the destination IP of the packet to the routing table for comparison according to the longest matching principle. Finally, Forward the packet. Therefore, traditional IP routing can only be routed based on the purpose of the data. 5 After completing the above steps, the logical etherchannel interface is set up. Network 5.5.5.5 0.0.0.0 area 0 RIP based on rumor 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 Neighbor 10.1.23.2 remote-as 200 Apply the configured ARP ACL to the DAI. For example, the following three types of point-to-point transmission services: Metric Make a summary on R3 , use aggregate-address summary-only as-set , note that the as-set keyword is added. Management distance ( Administrative Distance , referred to as the AD ) Support PVST Ip prefix-list FILTER deny 1.1.1.0/24 ip prefix-list FILTER permit External route tag Configuring a sample RIP environment Layer 2 switching Next Hop Several problems with VTP 100 10.1.13.1 Summarized as follows: *>i100.0.1.0/24 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 . Match x1 match x2 , x3 set Y OSPF redistributes routes to RIP : Ip summary-address rip xxxx yyyy // Note that this summary does not support CIDR supernet . The above command will also tag native vlan External BGP Switch(config)# interface fast0/1 Switch(config-if)# switchport Switch(config-if)# switchport mode access Path R1(config-router)# network 12.12.12.0 mask 255.255.255.0 R1(config-router)# distribute-list prefix 11 out OSPF redistributes routes to RIP : BGP routing table entry for 11.11.11.0/24, version 5 In general, we will establish an EBGP neighbor relationship with the IP of the direct interface .
