Match the AS_PATH that does not contain any AS number , that is , the route in the AS . Note inconsistent with err-diasble difference is, ERR-disable will disable off the entire interface, and inconsistentport is for a particular VLAN 's. Network without mask is a class declaration, plus the mask is no class declaration Rl , R2 , R3 running the OSPF , R3 routing table is as follows: Neighbor 10.1.23.3 route-map setComm in Otherwise the flag field is obtained by some calculation (as part of the verification process) The above match statement is used to match the neighbor IP that sent the summary route . If you specify a copy attributes option, is inject the specific routes will inherit the path attribute of the aggregated route, or breakdown will be as locally generated routes. R3 Using ICMP protocol to detect 10.1.1.2 reachability (source address 10.1.1.1 to ping10.1.1.2 ) Track Object 's ID is 1 , associated to ip sla monitor 1 Interface vlan 10 All VLANs The experiment is completed here, we set MARK , then we will analyze the impact of various attributes on the routing. The difference between set ip next-hop and set ip default next-hop is relatively simple,ccnp route labs gns3, it is not resolved here. Note that there must be three layers between the DHCP server and the trunk interface. Because the unicast packet is relayed, the source address is the trunk interface configured with ip helper-address . Therefore, when the DHCP server returns the packet, the destination IP address of the packet. This is the interface IP of the interface configured with ip helper-address . Router bgp 300 Route reflector planning principle Ip address 100.0.1.1 255.255.255.0 The solution is as follows: 1. On the R3 , declare the directly connected network segment of 10.1.13.0 into OSPF , and R5 is the same; 2. Modify it on R3 . Aggregate-address summary address suppress-map xxx as-set State BGP current callback state is basically opensent, etc., admin indicates that the neighbor is managed-type shutdown , when Multicast packets, one for each address that was learned on the interface. You can limit these bursts of multicast traffic by reducing the max-update-rate parameter (the default for this parameter is 150 packets per second). However, if you enter zero Station-learning frames are not generated, so the spanning-tree topology converges more slowly after a loss of connectivity. Length of the suboption type When a data frame is sent from a trunk port, the frame is sent directly. Metric problems 44 Access port processing frame process Route-map WT1 permit 20 match ip address prefix-list 2 set weight 100 The switch configured with Uplinkfast needs to be a stub switch or an access layer switch in the network three-layer structure. It cannot be the root bridge. Switch(config)# spanning-tree vlan vlan-id priority pri Since the flash space is very limited, it is recommended to store the file on the TFTP server. When deploying on a TFTP server, be careful to first create an empty file to correspond to the URL in the configuration command . This file is used for dhcp snooping bingding database writes (depending on the device). After being injected into EIGRP , the tag is still carried. If R1 turns on auto-summary and network 10.0.0.0 , the subnet will be automatically summarized to R2. Advertised to update-groups: 1 If the routes are from EBGP neighbors, it is preferred that the oldest EBGP neighbor came routing, reduce the impact of the roll (this provision mainly EBGP Switchport trunk encapsulation ? switchport mode trukn switchport nonegotiate Exactly the same, except that the list of AS numbers belong to the local Federation AS Offset-list { access–list-number | name } {in|out} offset [ interface-type interface-number ] 100.0.1.0 the BGP route, preferably up to R5 .

In other words, if a port loses its connection, it is no longer considered a topology change, which is different from 802.1D . Ip route 2.2.2.0 255.255.255.0 192.168.13.1 HSRP Use the show spanning-tree inconsistentports command to view related entries. Detailed rules ? BGP introducing and transmission routes Define set action If the above into OSPF , is invalid, i.e., the static route is associated interface, in OSPF the network when the network routing number, and will not be declared into OSPF . Network If multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred . After the maximum number of allowed MAC addresses of the port-security interface is set , the security address entries associated with the interface can be obtained as follows: The cost of the route. Switchport access vlan 100 interface fast0/24 Configuration example: Neighbor R3 filter-list 1 weight 4000 ( Well-known discretionary ) Default route The default keyword has a lower priority than the detail route.

Message life Because when actually deployed, SVI mouth may be more, go to if one of the no passive-interface to configure the amount may be relatively large, so you can choose to passive-interface defaut all interfaces of all passive off, and then a single interface to no passive -interface . Verify the value of experiment 1 ORIGINATOR_ID Must be zero Sourced in sev-epoch 1 Encap length 14 This global configuration command enables PBR to take effect on locally originated traffic. LocPrf The first 8 bits of the route must match the first 8 bits of 172.0.0.0 , the other bits do not care, and the mask must be /8 , /9 , /10 , ..., /24 This is the general case, of course, there are two situations, it depends on the specific environment and the specific routing protocol. This environment is relatively simple, PC and DHCP server in the same VLAN , I mainly want to confirm that the ordinary switch pair is carried Create a secondary VLAN : V1 uses broadcast, which is sent every 30s by default , using UDP port 520 (source, destination port) MED : 200 / / Use the federal member AS number to establish BGP Tunnel Tunnel interface * i100.0.1.0/24 8.1 Overview 91 Ip default-gateway 192.168.100.254 Interface fast0/0 1> Soft reset using updated routing information Match abd , abcd , abccd , abcccd, etc. Redistribute static At another point, R2 will take 10.0.0.0 , 11.0.0.0 (the network segment where the secondary address is located), and 1.0.0.0 and 3.3.3.0 from their own loopback.

Port number 521 110 Under normal circumstances, Rl is possible to ping through 3.3.3.3 , but if R2 f0 / 0 port agent arp turned off, then it ping nowhere outlet associated with the use of static routing, the router will route to the destination address that is the local chain Road, so send arp request for mac of 3.3.3.3 , and Async Async interface SW1(config)# interface fast0/23 The data is two-way.

After the maximum number of allowed MAC addresses of the port-security interface is set , the security address entries associated with the interface can be obtained as follows: General BGP routers do not accept containing its own AS routing information number, but can neighbor routing sources neighbors allowas-in a few of my as numbers , to make an exception. Show ip dhcp binding Show dhcp binding on DHCP server Multilink Multilink-group interface Next Hop Next Hop Router ospf1 Via 10.1.13.3, FastEthernet1/0, 0 dependencies The redistribute local route learned from the IGP routing protocol enters BGP , and the MED value inherits the metric in the IGP protocol. Enhanced Interior Gateway Routing Protocol (EIGRP) ISO IS-IS command Then on R4 , you can only learn 1.1.1.0 . We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows R2 configuration is as follows Neighbor 5.5.5.5 update-source Loopback0 neighbor 5.5.5.5 next-hop-self Flooding the MAC table to the above port If the MAC address is not in the security address entry and the security address has reached the maximum number, the illegal data will be discarded only. The legal data will be forwarded as usual without triggering a syslog message. The " Security Violation Count " under the interface is not. Will add 1 . If it is restrict , the illegal data is discarded, and a syslog message is triggered at the same time . Furthermore, the Security Violation Count is incremented by 1 , and the legal data is forwarded as usual.
