Match ip address Represents a range. Matches only one of the characters contained in the range. Abc?d VTP Operating Mode : Server Maximum VLANs supported locally 1005 Bgp bestpath as−path ignore This command, if configured, skips this rule EIGRP also supports tags . ^10. OSPF Whether the MAC correspondence is legal Set the timer of STP Start a TCP connection. Prepare enough resources when BGP is enabled For the above problem, we can set the Fa0/0 port on the router to passive-interface . As a result, the interface will not send OSPF Hello messages. At the same time, the network segment 192.168.1.0/24 associated with the interface will still be Be declared into OSPF so that you can avoid unnecessary Set default interface specifies how to send such a packet Switch(config-if)# switchport trunk native vlan ? Interface loopback2 // in R3 is only 1.1.1.0 route, that distribute-list 1 out here this command, all externally injected into the Neighbor 10.1.23.3 remote-as 300 2 state changes,ccnp switch layer 2 technologies, last state change 00:07:34 Virtual IP address is 10.1.1.254 Show ip bgp 10.10.10.0 on R3 CISCO private, the scope of this router is (not passed), this value will not be included in the update message, nor will it be passed to any 100 Look at the top of topology, AS300 has a subnet 172.16.1.0/24 , AS400 has routes 172.16.2.0/24 . Match ip address prefix-list 1 set metric 200 Ip community-list 11 permit 100:11 A route-map defined on the interface . In this way, only the PBR action will be performed on the traffic entering the interface . The traffic originating from this device is invalid. No synchronization When configuring the reflector, the client- to- client reflection is enabled by default, but if the client is fully interconnected, this command adds no to turn off the reflection between the clients. The GW configuration is as follows: Looking at the above picture, we made a manual route summary on R3 . This summary route was generated by R3 and passed to R4 . At this time, the AS_PATH of this summary route is 300 , and the detailed route under it is lost. AS_PATH attribute, then if R4 and R1 or BGP activity 1/0 prefixes, 1/0 paths, scan interval 60 secs BVI Bridge-Group Virtual Interface ! ! Automatic generation We look at the above picture, the external detail route 172.16.32.0 – 39.0/24 , and the summary route 32.0/21 are introduced into OSPF by R1 , now Four types of AS_PATH path attributes In this case R1 on to R4 used strategy, 10.0 route AS_PATH insert 100 of AS number, while the results for the R4 over (64514) 100 100 , on the other side of R3 over 300 200 is 100 , R5 still preferably R4 , as ( 64512) Does not participate in the AS_PATH length calculation. If the switch does via a untrust interfacing a downstream switch, and release of the desired received by the interface, with a downstream switch sends out option82 of DHCP messages, use the global command: IP Information Option DHCP Snooping the allow-Untrusted , while Because it is a DHCP packet received through the untust interface , a DHCP snooping binding database entry is created based on the result of the interception .
