Version 8bit , V4 currently uses more versions ...... 192.168.8.0/24 Ip dhcp relay information trust-all Offset-list Acl number in/out offset value interface / / Modify the default parameters The configuration of R2 is as follows: Route-map test permit 20 Redistribute BGP 1 subnets route-map BGP2OSPF1 Set community no-advertise route-map setCommu permit 10 router bgp 300 Display BGP tables, for example: Switchport port-security mac-address sticky At the same time, if 172.16.1.0 and 172.16.2.0 are all DOWNed at this time , the summary route also disappears. Command This global configuration command creates a route-map that uses a custom string to represent this route-map . You can do this in a * i The direct result of this command is that the metric of 192.168.12.0 in R3's original routing table is 30720 , but now it is 10000 , which becomes 40720 . We see that after the offset command is configured , what actually changes is the DLY that is updated to the neighbor . Because it is true that DLY is the best, the default Therefore, the role of the no-prepend keyword is: Do not prepend local-as to updates from ebgp peers . If you advertise the route to the EBGP neighbor of the primary AS , the secondary AS number is not attached . parameter " The When A Receives A Configuration Switch that the contains the BPDU Superior Information (Lower Bridge ID, path cost Lower, and SO Forth), IT Information Stores The Port for that. The this the If the BPDU IS ON The Received the root of The Port Weight Family Identifier ) Ip community-list example 1 : Ip policy route-map PBR After bgp confederation iden 345 configuration, for the federated AS , this AS is not what 64512 , but 345 Gateway of last resort is 172.16.3.0 to network 172.16.0.0 The MAC sublayer is physically layer-dependent,ccnp route hands on labs, that is, different physical layers have different MAC sublayers for access. In Ethernet, there are two main types of MAC : Match ip address 1 set metric 10 //The effect is the same as above This feature is quite unstable and is not recommended. BGP table version is 3, local router ID is 3.3.3.3 Lowest sender bridge ID Ip arp inspection vlan 100 logging acl-match none R1 Router ospf 1 Management VLAN in a Layer 3 switch environment inQ number of messages waiting to be processed from this neighbor The default is shutdown , optional protect , restrict R1 and R2 run RIP ; R2 and R3 establish OSPF neighbor relationships. In the initialization case, there are four entries in the routing table of R2 , as shown in the figure above, and there are only two entries in the routing table of R1 , that is, two direct links. So now, we do the re-release action on R2 , and redistribute the OSPF route to RIP , then the configuration is as follows: 10.1.12.2 Passive-interface configuration Vlan 100 Multilink Multilink-group interface 2.2.2.2/32, version 55, epoch 0, per-destination sharing 0 packets, 0 bytes BGP anti-ring is implemented through AS_PATH , and AS_PATH is only changed after the route leaves the AS . Therefore , IBGP does not have EBGP anti-ring capability in the AS . To prevent loops, BGP routers will not be from IBGP neighbors. The learned route is advertised to other IBGP neighbors. Network 10.1.45.0 0.0.0.255 area 0 ? Update message: contains the entire routing table, updated periodically Dhcp-bindings none —Does not log packets that match DHCP bindings. Router bgp asnumber PA , sets the traffic of a specific community tag to traffic-index . The configuration is as follows: ip route 172.16.1.0 255.255.255.0 192.168.12.1 !! go subnet route Address Resolution Protocol Synthesis example 1 : Default Port-Security configuration Ip mtu ? refers to the three-layer MTU . This value can be manually modified, but the maximum value must be less than the interface's Layer 2 MTU value, which is 1500 . This MTU refers to the total size of the three-layer IP packet. If the packet sent by the interface is larger than the ip mtu of this interface , the IP packet will be fragmented. or 5.5.5.5 100 Store the result of the CRC cyclic redundancy check VID Path Remote-ID type UDLD mode of operation If both commands are closed: COST community : ? When, the AS_PATH only AS300 , 400 , and thus be B router to accept a summary of the article (because do not see their own AS number appears in Complete basic configuration 2 R3 and R4 , R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . 10.1.13.1 S0 DCE Match, and the result is that there is no match, it is directly discarded, regardless of whether there is a valid entry in the DHCP Snooping database . After deploying loopguard : 1083 This has already been said before. Match ip address prefix-list 1 set weight 100 ATOMIC_Aggregate The type parameter in the above command is used to indicate the hardware type of this hardware address. If type is 1 , the type is ethernet , if type *> The configuration of R2 is as follows: Interface fa1/0 Match ip address 1 Router(config-dhcp)#default-router [host address] Switchport access vlan 100 interface fast0/24 Then you can use the route-map tool, that is, we can associate a route-map with the re-release , to implement the function I just mentioned. Of course, this time 1.1.1.0 is unable to access 3.3.3.0 , because R3 does not have a route in the RIP routing domain (that is, there is a problem with the backhaul routing, data communication must always consider the round-trip path, remember), so if To achieve network-wide interworking, you need to be on R2 : Configuration Example PAgP mode: R3 configuration is as follows ? The set statement cannot be included in the Policy-list , but after it is called by route-map , the route-map can contain the set statement. Fa0/20 Ip address 10.1.13.1 255.255.255.0 AS Hops 1 RFC1722 Sh ip bgp neighbors {address} advertised-routes DHCP is very familiar. For the DHCP client, the initial process is to find DHCP by sending a broadcast DHCP discovery message. Rl , R2 , R3 using LOOPBACK neighbor relationship with the address of 1.1.1.1 , 2.2.2.2 , 3.3.3.3 , running OSPF such Support PVST Ip address 192.168.100.1 255.255.255.0 r >i1.1.1.0/24 The Sticky Secure Address is a secure address that allows us to change the Port-Security interface to a "sticky" MAC address through dynamic learning so that it is not lost due to up/down of the interface . However, if we want the sticky security address entry to still exist after the device is rebooted , then we need wr . Write the configuration to the start-up config file. The Sticky Secure Address is also a great tool to simplify the operation of our administrators. After all, there is no need to manually tie them.
