Set the commu value to append, otherwise override Disable port Looking at the above picture,ccnp switch lab 10-1, 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 Precautions Flooding the MAC table to the above port * i //The default community is not sent, so this command must be configured To 100 end of the AS_PATH , which is the route originated in 100AS route The protocol for RSTP BPDU is 2 and the version is 2 . match. As long as the community contains 100:11 or no-export R1 uses 1.1.1.1 as the update source, trying to establish a BGP connection with 2.2.2.2 , and the local IP address of R2 is 1.1.1.1 , and By default, no rate limit is configured. 200 i Route-map defaults to permit , the default serial number is 10 , the serial number is not automatically incremented, and the serial number needs to be specified. Confirmation of TCA ( MSB set) to the previous switch. When the root receives the TC , it sends the TCA back to the original sending switch and sends the TC ( LSA set) to all bridges . Switch receives ROOT issued to TC after, will MAC aging time address table is reduced to 15s The WEIGHT attribute is a CISCO private attribute. The scope is this router (not passed), the value is not included in the update Mechanism overview The dst-mac detects the received destination ARP packet. The destination MAC address of the Ethernet frame header is the same as the target MAC address in the ARP body . This check is for ARP response . When this option is enabled , ARP packets are discarded if the two MAC addresses are inconsistent. Configure ARP packet rate limit Neighbor 10.1.25.5 remote-as 345 no auto-summary Vlan range and mapping Ip community-list 11 permit 100:11 V1 defaults to send v1 to receive v1, v2 Send Open package Ip next-hop recursive Before routing 0bits must 0.0.0.0 ago 0 Ge bit match, in fact, all the bits does not matter, but also for the mask, that did not write ge keyword is implicit so ge 0 Le 32 , that is, cover The code length is greater than 0 and less than or equal to 32 . So this prefix list is permit Connection-oriented and reliable data transmission service After an ARP ACL , if ARP packets are denyed by the ARP ACL , these packets are directly discarded, even in DHCP snooping. Basic 28 Management distance ( Administrative Distance , referred to as the AD ) Ip address 4.4.4.4 255.255.255.0 The router goes to update the route of 3.0.0.0 The network learns the route learned from the IGP routing protocol into BGP . The MED value inherits the metric in the IGP protocol. Ip address 10.1.25.5 255.255.255.0 BGP table version is 3, local router ID is 3.3.3.3 s> 172.16.10.0/24 1 : RIP-1 ; The configuration on R3 is as follows: Also a route prefix may carry multiple community to form a list, if you want the original route for a particular community to add a foundation community , then the route-map in the set community , the increase in additive keywords. When the RR sends a route update to an EBGP neighbor, it will be aware of the existing CLUSTER_LIST attribute. FastEthernet0/0 R3 sets the tag when injecting the route. The smaller the MED, the higher the priority Acl-match none —Does not log packets that match ACLs. Path R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. If the number exceeds xx , disconnect the BGP connection with the neighbor and reconnect after 2 minutes. Port Vlans allowed on trunk Port role: Switch(config)# spanning-tree portfast bpduguard default When a data frame is sent from the Hybrid port, the switch determines whether the attribute of the VLAN on the port is Untag or Tag . If it is Untag , first strip the VLAN tag of the frame and then send it; if it is a Tag , send the frame directly. Access-list 2 permit 192.168.3.0 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.
