? 200 300 Neighbor RC-ip remote-as 100 The configuration of R5 is as follows: Cause: After the ARP Request is sent ,ccnp switch training, the ARP Reply is prepared for a large number of reasons: scanning on the same network segment (host), scanning across network segments (network device) By modifying the weight to influence the routing decision Match ip address Bgp bestpath as-path ignore Therefore, when the deployment is re-released, this problem needs special attention. As for how to avoid the problem, I will introduce it in the following content. No synchronization In R1 the ip route 0.0.0.0 0.0.0.0 null 0 then re-released in a static routing process, but also to Enhanced Interior Gateway Routing Protocol (EIGRP) Open Shortest Path First (OSPF) Route-map defaults to permit , the default serial number is 10 , the serial number is not automatically incremented, and the serial number needs to be specified. -------------- Layer 2 interface (switchport) : access mode, trunk mode When the router is adjacent to the host, they learn in some way. Other applications of regular expressions in CISCO IOS Passive-interface defualt Next Hop ( Optional non-transitive ) Exchange network security Neighbor table BGP path attribute The path is rejected by the inbound BGP policy, and the router is configured with soft reset. Access-list 1 permit 1.1.1.0 0.0.0.3 route-map test permit 10 The cost of the route. Router bgp 345 length Ip route-cache flow show ip cache flow The current status of the Port Status : Secure-up !! interface is up . 10.1.12.0 [110/128] via 10.1.23.2, 00:06:40, Serial0/0 Enhanced Interior Gateway Routing Protocol (EIGRP) ISO IS-IS *>i100.0.2.0/24 In order to verify this rule, we first maintain the basic BGP configuration. Introduce 100.0 by using network on R1 On R2 , going to the 100 network will use R1 and R3 as the next hop for equal load balancing (although R3 's uplink port has smaller bandwidth, but it is directly connected). 100 The next-hop attribute can be changed by next-hop-self Match ip address 1 router bgp 100 This global configuration command enables PBR to take effect on locally originated traffic. A support DHCP Snooping switch, if it untrust interface, received from the downstream transmission of the switch, and with option82 the DHCP message, the default action is to discard these packets. If the switch is turned on the DHCP Snooping and with option82 the DHCP message is trusted received on the interface, the switch will receive these messages, but does not create a message based on information contained in the DHCP bingding databse entries.
