Fast switching type 1, interface type 18 IP CEF switching enabled R2(config-router)# distribute-list 1 out fa 1/0 Packets ( Routing Table ) , the routing table is loaded with routing entries ( routes ) learned by the router . The routing entries are composed of routing prefixes (destinations associated with routes), routing information sources, outgoing interfaces, or next hop IPs . The router obtains routing entries and maintains its own routing table in a static or dynamic manner. RIP-2 Only Suboption type Weight Route-map test permit 10 R1 , R2 , and R3 run RIP and only announce the direct link between the three. In R1 the ip default-network 172.16.0.0 OPEN message i FastEthernet1/0 However, if the R1 release carry on a tag external routes, and R2 re-released on OSPF into RIP , tag lost: Ip address 192.168.100.254 255.255.255.0 The IP header is 20 bytes, the ICMP header is 8 bytes, and the ICMP data payload is 1472 bytes, which is exactly 1500 bytes. Therefore, on the CISCO IOS device, the size followed by the ping refers to the entire size of the outgoing IP packet. CASE2 : *> 100.0.2.0/24 Ip dhcp snooping vlan 10 Interface fast0/1 Policy deployment in BGP Interface vlan 10 MAC sublayer Next Hop MD5 digest : 0x73 0x52 0x60 0xE7 0x4D 0xA5 0xC7 0x4F 0xCA 0x3D 0x6F 0x1D 0x3F 0x23 0x03 0xBB Match ip next-hop matches the next hop address to those allowed in a particular access list The so-called seed metric refers to when I use a route to re-publish from an external routing protocol to this routing protocol, if the metric of the route is not manually specified , the default metric is used . Look at the following table (the following table is a recognized default value that can be modified using the default-metric in the routing process ): The configuration of R2 is as follows: Switchport access vlan 10 interface fast0/24 State is Listen When an RSTP switch detects a topology change it will: Configure the Port-Security penalty mechanism The weight of the BGP route generated by the local summary is also 32768. Let's analyze that SW1 inserts the DHCP request message from the PC into option82 and then sends it to SW2 . Via SW2 ! Route-map test permit 20 router ospf 1 After completing the configuration, R2 show ip route Ospf rip static Whenever a route is reflected by the reflector, the cluster -ID of the reflector (the cluster) is added to the route's Cluster-list attribute. Exact match Protected port Ip prefix-list 1 seq 5 permit 1.1.1.0/24 route-map test permit 1 If you want to delete multiple communities (not all), you can write multiple items in one community-list , such as In the above figure, we inject OSPF routes into RIP . Traditionally, you can only set metrics on all incoming routes . However, with route-map ,ccnp 300-135 book, we can associate a defined one when configuring re-issue commands. A good route-map , in the route-map , we can create different properties or actions for different routes by creating multiple serial number statements. * i Due to the different port types, the switch processes the frames differently. The following is introduced according to different port types. This type of data transmission service does not need to establish a connection, but it adds an acknowledgment mechanism to the transmission of data, which greatly increases the reliability. Router bgp 345 Acl-match none —Does not log packets that match ACLs. If the routes are from EBGP neighbors, it is preferred that the oldest EBGP neighbor came routing, reducing the impact of roll IP Address Note inconsistent with err-diasble difference is, ERR-disable will disable off the entire interface, and inconsistentport is for a particular VLAN 's. Protected ports are not able to communicate with each other although they are in the same VLAN . In general, a Layer 3 switch contains two types of ports: Layer 2 interface L2 and Layer 3 interface L3. Configuration and implementation Note that the as-path access-list is also implicitly rejecting all by default. Solution 3 : DAI So looking at the above picture, two VLANs are created on the Layer 3 switch : 10 and 20 , and the addresses of the SVIs of the two VLANs are assigned as the user gateways of the respective VLANs , so that the routing table of the switch is There are routes for two VLAN segments. Then, when the two VLANs need to communicate with each other, the user of VLAN 10 will drop the data to his own gateway, that is , the SVI of VLAN 10. After the data arrives at SVI10 , the Layer 3 switch looks up the table and finds that the destination is the network segment where VLAN 20 is located. Throw the data out of VLAN 20 and eventually reach the destination VLAN 20 of the PC .
