The adjacency list in the CEF component is used for MAC or Layer 2 rewrite information. Establish BGP neighbors A frame whose type field is 0835 represents an RARP protocol frame. Router (config) #server dhcp turn on DHCP services. By default, the Cisco IOS DHCP server and relay agent features are enabled on your router The pVLAN must be configured on a switch in transparent mode. Also requires VTP version 1 or 2 . It is forbidden to configure the Layer 3 VLAN interface as a secondary VLAN . 10.1.12.1 from 10.1.12.1 (1.1.1.1) Looking at the above picture, we made a manual route summary on R3 . This summary route was generated by R3 and passed to R4 . At this time, the AS_PATH of this summary route is 300 , and the detailed route under it is lost. AS_PATH attribute, then if R4 and R1 or ... (maximum 25 ) [Experiment 7 ] There are subnet routes (no match); there are default routes Then 1 , 2 compare first, 1 is preferred (because 1 has a smaller MED ); since 1 and 3 are in the same AS , so again The decision process of BGP is to use the local routing policy for the routes in ajd-RIBs-IN , and put the selected or modified routes into Loc-RIB and The out- direction policy cannot be used separately for the member of the peer-group . It can only be used for the entire group . The in direction does not have this restriction. All neighbors in the same peer group must be all iBGP neighbors or all eBGP neighbors.

A strange phenomenon has appeared. It seems that R4 does not reflect the route from R5 to R3 . Why? In theory, the RR will learn from non- client of IBGP neighbor to route reflection to their Client , but it is clear, in this experiment, R4 and did not learn from R5 route reflection to their Client . FastEthernet0/0 Port-channel interface cannot be the destination interface of SPAN 159 220 , 91 70 The default load balancing method is destination-based load balancing. CEF 's destination-based load balancing is actually implemented by HASHing the destination and source IP addresses . In contrast,ccnp tshoot topology, in fast forwarding, load balancing based on destination address is performed strictly according to the destination IP address.
