AD When a route oscillates (continuously fails, recovers), it is assigned a penalty value. The more the swing, the larger the penalty value and the constant accumulation. The result found can be understood as a pointer to find the associated outbound interface: We use ip ospf cost 100 on the F0/0 port of R4 to increase the interface cost , so the result is as follows: 100 View and verify A frame whose type field has a value of 0800 represents an IP protocol frame. Tunnel Tunnel interface Internal Frames with a type field of 8137 represent IPX and SPX transport protocol frames. Ip community-list 11 permit 100:11 CISCO data forwarding mode Redirect time 600 sec, forwarder time-out 14400 sec Preemption disabled Precautions: When ISP1 is down, the interface of GW connected to ISP1 is DOWN , and the traffic of PC access 100 is automatically switched to ISP2. Virtual-PPP Virtual PPP interface Virtual-Template Virtual Template interface Clear ip bgp * IP nodes can communicate, and communication is actually the process of data interaction. Data interaction requires network devices to help us transfer data between two communication nodes. When the router (or other Layer 3 device) receives an IP packet, the router will find out the purpose of the IP packet in the Layer 3 header. The secure address entry can be configured by using the MAC ( SecureDynamic ) dynamically learned by the port , or by manually configuring the interface ( SecureConfigured ) and the sticy MAC address ( SecureSticky ). None Match metric matches the route with the specified metric. match route-type matches the specified type of route match community matches the BGP community. AS_SEQUENCE exactly the same, except that the list of AS numbers belong to the local Federation AS Router(config-router)# R 3.0.0.0/8 is possibly down , routing via 9.9.12.2, FastEthernet0/0 In the above figure, we inject OSPF routes into RIP . Traditionally, you can only set metrics on all incoming routes . However, with route-map , 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. Configuration example 46 The security address entry thus formed (which is SecureSticky ) will not be lost even if the interface is flipped. If wr saves the configuration and the command is written to config.text , the security address will not be lost even if the device is restarted. Ethernet data link layer Although RIP is running between R1 and R2 , the routes of 1.1.1.0 and 2.2.2.0 are updated with each other , but since R1 is from RIP and his Optional delivery to simplify the execution of routing policies The routing between the internal LOOPBACK of the AS can be learned separately. Both R1 and R3 update the route of the 100 network segment to R2 . Without any policy,ccnp route master study guide, the BGP routing rule will always be compared to the RID , and finally the route of R1 is preferred . Accept either real AS or local AS from the ebgp peer . Translation: EBGP peers can use either PriAS or SecAS to local remote-as . For example, after configuring the above command on R2 , R3 is 10.1.23.3 . In its BGP process, you can use neighbor 10.1. 23.2 remote-as 200 , you can also use remote-as 201 to refer to BGP neighbor R2. Exit : Disabled 5.5.5.5 // This command is used to advertise the real AS number of the AS outside the federation . Detailed rules Major Points In a route-map statement, if there is no match statement, match all Affect routing decisions by modifying weight 10 2.2.2.2 Another recommended solution is to adjust the management distance of the routing protocol: C Border Gateway Protocol (BGP) Connected Router bgp x Configuration example 58 Set the channel-group ID AS_SEQ type is {100 , 200} in this segment is AS_SET type. So AS_SEQ the AS_PATH used to identify the origin of this summary route, it is ordered AS list, in addition AS_SET this AS_PATH type used to identify the details of pre-aggregated 10.1.13.3 // There are routes in the routing table of R3 : 1.1.1.0 , 2.2.2.0 , 192.168.12.0 0xFFFF RIP message format 31 VTP configuration 30 Match ip add pre 1 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 : Access-list 1 permit 11.11.11.0 The default is shutdown , optional protect , restrict Match ip address matches the access list or prefix list Note that the main TC while timer is timed on the port, and the BPDU sent by the port will be set by the TC bit , and the BPDU will also be sent out from the root port. BGP , the IBGP neighbor relationship is established between the BEs . If A has a network segment 1.1.1.0 , A injected into the BGP , and transmitted to the EBGP neighbors B , Management MAC table Weight RIP-2 RIPv2 uses multicast update BGP routing rules 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.
