Name server After PK , there is no doubt that the default route pointing to telecommunications appears in the routing table, and points to the default route of the education network, "wacky" to hide. When the default route to the telecom is invalid, it disappears from the routing table. At this time, the default route to the education network is "floated". Request specific routing information: When it is necessary to know the information of a specific route or some specific routes, the request message will be sent together with the routing entry of the specific address. The device that receives the request will process the entries one by one according to the request message and form a response message. switchport trunk encapsulation dot1q switchport mode trunk Untitled-1 Set ip default next-hop 10.1.12.1 Root port: The interface that receives the optimal BPDU is the root port. This is the closest ( cost minimum) interface to Root . ! Type echo protocol ipIcmpEcho 10.1.1.2 source-ipaddr 10.1.1.1 frequency 10 External Sh ip bgp neighbors {address} received-routes ? BGP If there is no tag , mark the PVID of the trunk port and proceed to the next step. Let's take a look at this route 100.0.1.0 : Optional delivery to simplify the execution of routing policies Initially, R3 can learn three loopback routes from R1 and 192.168.12.0/24 routes. Now we don't want R3 to learn the route to 192.168.3.0/24 , then we can configure it on R2 as follows: If there is no tag , mark the PVID of the Access port and proceed to the next step. Configuration example (allocating community for routing ): About the rate_in_pps parameter: LocPrf OSPF routing: including 3.3.3.0 , and the direct connection network segment 192.168.23.0/24 declared into OSPF is injected into the EIGRP process. This R1 The interface will not send BPDUs , and will also ignore received BPDUs. Configuring bridge priority R3#show ip bgp Bgp confederation peers 64513 Types of VLAN IDs of the allowed VLANs when this port is in trunking mode add VLANs to the current list Connected, and can update and deliver BGP routes. The router goes to update the route of 3.0.0.0 RIPv2 manual summary R4 released the RIP route of 100.1.1.0/24 , which can be learned by both ASBRs . The solution is to configure static summary routes on the two ASBRs : Another way is to use ARP ACL : ARP packets are detected and released directly. For untrusted interfaces, ARP packet after receiving back checks only legitimate ARP packets can not be released, if the emergence of illegal ARP packets, it will be log , while discarding. Each group of GLBPs can have up to four member routers as ip default gateways. These gateways are called AVF ( active virtual forwarder ). Assigning community 100:11 to route 11.11.11.0/24 on R1 and passing it to R2 , then R1 is configured as follows: Ip address 192.168.10.254 255.255.255.0 200 The secure address formed by the dynamically learned MAC is valid. If the MAC is in a failed state within 50 minutes (for example, the host is offline), the secure address is cleared after the aging time expires. Switchport access vlan 100 interface fast0/24 The router goes to update the route of 3.0.0.0 Match ip address 1 set tag 10 0 100 i MED : 150 Enabling BPDU filtering on an interface is the same as disabling spanning tree on it and can result in spanning-tree loops. The Protected port feature cannot be configured across switches: Ip default-gateway 108 Router rip Flag: 0x860 Route-map COST1 permit 10 match ip address prefix-list 100 The least significant bit of the LSB indicates the TC flag; the most significant bit of the MSB indicates the TCA flag. Neighbor 5.5.5.5 weight 100 Weighting 100 (default 100), thresholds: lower 1, upper 100 Migrate to the Established state if you receive a keepalive message from the other party The default bridge priority of the switch is increased to a higher value than the default ( 32768->49152 ) so that the switch does not become Root. Vlan range and mapping The configuration of R4 is as follows: Spanning tree is used to solve this problem This is a feature that is used in large and medium-sized networks to make the configuration "modular". None does not send updates ( passive ) When no BPDU is received for a period of time and the lifetime reaches MAX age , the bridge considers that the port is connected. R1 , R2 , and R3 run RIP , and 1.1.1.0/24 on R1 is not directly announced. On R2 : 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 Hostname R1 interface s0/0 When port-security mac-address sticky is activated on the interface , then: On this topic,ccnp switch example questions, the individual feels that there is no need to study it. It does not make much sense for the research of class-based routing protocols. No matter the actual application or the LAB exam, it is no longer involved, and you are interested in making it yourself. In the outbound direction, the distribution list can only work on the ASBR that performs the route redistribution action , and can only work on externally imported routes. Because OSPF performs re-release, these external routes are actually imported in the form of routes. Therefore, the distribution list can work normally in this case, but if it is not a local originating external route or an internal OSPF route, the out direction The distribution list is at a loss.
