Port-Security and Sticky MAC Address The switch receives the DHCP request , which inserts option82 information into the message (of course, you must do the corresponding configuration first). In the inserted information, the remote-ID suboption is the MAC of the switch ; the circuit-ID suboption is received. The interface ID to the DHCP request message . The VTP protocol sends a VTP notification every 5 minutes or when there is a change; 1.1.1.1 (metric 129) from 4.4.4.4 (4.4.4.4) Show ip b rib-failure This global configuration command enables PBR to take effect on locally originated traffic. 10.1.13.1 R1(config-router)# network 192.168.12.1 0.0.0.0 area 0 R1(config-router)# distribute-list 1 out Access-list 1 permit 1.1.1.0 Route-map nat3 permit 10 match ip address 2 match interface serial0/1 table of Contents 5.5.5.5 Experimental verification Interface loopback0 The LSA sends the neighbor to the neighbor, so the local route is filtered, and the neighbor has (because the neighbor has received the LSA ).

If it is not optimized, it will not be loaded into the routing table. Then why is this? Note that the next hop of the two routes is 10.1.13.1 , and it is worth noting that the directly connected network segment of 10.1.13.0 is not declared into OSPF by R3 . In other words, R4 goes to the next-hop of the two routes. Unreachable, the next hop is unreachable. Therefore, although the two BGP routes are in the BGP table, they are not best and cannot be loaded into the routing table.
