Ip community-list standard del permit no-export route-map test permit 10 Switchport port-security maximum 1 vlan 10,20,30 !! can associate multiple VLANs Service dhcp 10.1.23.2 Because of this self-learning and two R1 of BGP routes NEXT_HOP property 10.1.13.1 are directly connected, is reachable, 5.5.5.5 The above interface will send BPDU ( a few ) immediately after the link up , and will not send any BPDU after that. Route summary issues to be aware of 100 i Network 10.1.25.0 0.0.0.255 area 0 1.1.1.1 Route-map test permit 10 If the local end has this feature enabled, the next-hop device does not support CDP , then switch to the next next-hop . If there is no next-hop , skip the PBR. Knowledge review Ip route 100.1.0.0 255.255.0.0 null0 ORIGINATOR_ID and CLUSTER_LIST Maximum-paths 2 The "original Ethernet frame" is up to 1518 bytes, the IP MTU of 1500 , plus the source destination MAC address is 12 , the type field is 2 , CRC4 , plus 30 bytes of ISL encapsulation, which is 1548 bytes. The default COST value of all ports on the switch will increase by 3000 , so that the port of the switch is not elected as the designated port. 200 i Network 100.0.1.0 mask 255.255.255.0 A frame whose type field is 0835 represents an RARP protocol frame. You can use show ip bgp regexp to check the results of the configured regular expression. When deploying the campus network, we often have the following special requirements for switches: Neighbor 5.5.5.5 update-source Loopback0 When the number of prefixes received from the neighbor exceeds the maximum number 300 of 90% (default 75% ), generating a message log Ip route 10.1.12.0 255.255.255.0 10.1.1.2 192.168.1.0 the OSPF routing but will be re-injected into the RIP (because we deploy a two-way re-release), this is the route Feedback , the route was filling back. Neighbor 1.1.1.1 remote-as 123 Ip dhcp snooping vlan 10 Interface fast0/1 Clear ip bgp * If the route is imported using the aggregate-address command, the MED is empty. HELLO time FastEthernet0/0 Vlans in spanning tree forwarding state and not pruned Of course it includes information such as object MAC address , contents of the destination interface . In this case we need only one data stream (Flow) in the first packet do process Switch(config-if)# spanning-tree [ vlan vlan-id ] cost cost Use clear port-security dynamic command to clear all port-security interface by dynamically learned secure address entry using clear port-security sticky command to clear all sticky secure address entries Note that the above is the default metric when re-publishing from other dynamic routing protocols into this routing protocol . If you republish a local direct connection or a static route, the situation changes,ccnp route flg pdf, as follows: Technical background 40 Route tag Tag 73 Access-list 1 deny 192.168.1.0 Complete the basic interface IP configuration . Add the following configuration on R2 : By using route tags in RIP , you can control the redistribution of related routes in other protocols. When republishing to other protocols, RIP routes simply compare the tokens assigned to them without comparing the entire route. ! Border Gateway Protocol (BGP) Connected Routing time: The time elapsed since the last time the routing entry was modified. The routing time is reset to 0 each time the routing entry is modified . Configure an interface as a passive interface: Offset-list offset list SW3#sh vtp status VTP Version capable VTP version running VTP Domain Name VTP Pruning Mode Origin IGP, metric 0, localpref 100, valid, internal 2011-12 Root modifies its own configuration BPDU to advertise the entire switching network about topology changes. Root sets the topology change ( TC flag) for a period of time in the configuration BPDU . This time is equal to the forwarding delay + Max. Age , the default is 35S. *version* 2 The same isolated VLAN and isolated VLANs cannot communicate with each other and can only communicate with the hybrid interface. OSPF , but R3 ignores this route (locally configured with a static summary route pointing to null0 ), although the LSA is still passed to R5 , which means that although R5 still has a 1.0.0.0/8 route, the packet After being thrown to R3 , it is finally discarded at R3 , so there is still a problem here. Private VLAN concept Send Keepalive bag If there is a class route lookup ( no ip classless and ip cef is off ), when receiving a data packet, the router first searches for the main class to which the destination address belongs. If there is a main class route in the routing table, then the subnet is searched. If there is a subnet route, the query is limited to these subnets and further searched. If the final lookup fails (no subnet matches this route), the packet is dropped even if there is a default route; if there is no local For the main class route, see if there is a default route. If there is, then it will be forwarded by default route. If not, the packet will be discarded.
