Neighbor xxxx soft-reconfiguration inbound In a real network environment, we may encounter a situation where there are two or more routing protocols in a network environment, for example: Match comprising 100 and 200 of AS_PATH Local 201 200 100 In order to let R4 know that R5 is its federated EBGP neighbor, instead of a normal EBGP neighbor, you need to add the following configuration: At the same time, the two routes are marked in the BGP table: " *> ", indicating that the two routes are valid , and the best or optimal, best , so they will be passed to the IBGP neighbor of R3 . That is R4 Neighbor 10.1.12.2 remote-as 200 * Ip address 10.1.45.4 255.255.255.0 Configuration command ( If MED is empty , it is set to 0) 2.2.2.0 Routing Although the next hop is directed to R1 , it does not use the outbound interface to create routing entries. From the experimental phenomenon, it is not matched by the match . Needless to say, 3.3.3.0 , the associated interface is s0/1 . AD 10.1.34.3 Cisco Private Version The idea of ​​configuration is that on R2 , you want to grab the fast0/0 port (that is, the one sent by R1 ) and go to the traffic of 30.30.30.0/24 . ? Dual two-way point of the route re-release ! Vlans allowed and active in management domain Each update message describes only a single BGP route. This is because the BGP path attribute can only describe a single route. Router(config)#ip dhcp pool [pool name] Between R1 and R2 , the original R3 and R4 are updated through a multi-access network, and BGP is run . Reviser Start a TCP connection. Prepare enough resources when BGP is enabled In Ethernet, different media access methods are provided for different duplex modes: R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. A router that does not support the route reflector function can act as a single router cluster or as a client Network xxx mask yyy route-map zzz The router goes to update the route of 3.0.0.0 802.1W Neighbor 10.1.23.3 dmzlink-bw The lower the value is set, the higher the protection level for the CPU . This value takes effect before and after the penalty action occurs. Of course, this value cannot be set too low. At least the legal traffic must be processed. Generally less than 1000 is almost the same. FastEthernet0/0 The default is 6 update cycles, which is 180s . The route entry tag when an entry with a larger hop count is received Vlan 10 basic concept Match ip address pref 1 set local-preference 200 Turn on switch interfaces Port-Security will consume resources, Port-Security detects an incoming interface to each data frame to determine whether the flow method,ccnp route blog, or if there offenses. When a security interface settings violation to shutdown when the interface is in violation After completing the configuration, R2 show ip route If you want to turn off ICMP redirects, you need to use no ip redirects on the interface . The longest match Ip dhcp pool BIND Atom character example: Ip dhcp pool BIND internal Atomic character Set ip next-hop 10.2.2.2 Ip dhcp pool BIND The above command will also tag native vlan [123].[7-9] * i The ORF feature is very simple, that is, R2 pushes this list to R1 , so that this strategy performs filtering on the R1 side, as shown below. Understand the invalid arp entry Experimental needs Interface trust status and network security issues The red font part of the above output is the layer 2 MAC information and so on. Le keyword is not written, then the default is greater than 24 less than 32 201 [Results] There is only 1.1.1.0 route in the routing table on R2 . Remote-ID type Ip prefix-list FILTER deny 1.1.1.0/24 ip prefix-list FILTER permit FastEthernet0/0 The smaller the total cost of the switch to reach the root switch path, the better, related to the interface bandwidth. Route-map test permit/deny 20 Route-map LP permit 20 match ip address pref 2 set local-preference 100 R1#show glbp Then, in order for R3 to dynamically learn the routing of production and office servers, it is now necessary to redistribute these two static routes into OSPF . Of course, there are tricks when re-publishing. *> 100.0.1.0/24 PVST+ Complete basic configuration 2 2 Static routes And SW3 on the same case Acl-match none —Does not log packets that match ACLs. After changing the topology, the interface IP of R2 has changed. At this time , the RIP sent by R1 is updated, and the source address is still 192.168.12.1 . After receiving R2 , it finds that the interface IP that is updated with the local is not in a subnet, so R2 ignores the update message of R1 . In addition, the message sent by R2 to R1 is accepted by R1 , because R1 thinks that the RIP update message source address 192.168.12.5 sent by R2 is on the same subnet as its own interface.
