At this time , OSPF routes are re-advertised to BGP on R11 , so that R12 can learn. After R12 learns the route, it finds that BGP attributes (including AS_PATH ) are lost. Because OSPF redistributed into BGP , the default does not automatically tag values are copied into the AS_PATH , the need to R11 on federal 10.1.12.0 [110/128] via 10.1.23.2, 00:06:40, Serial0/0 Show ip cef exact-route src-addr dest-addr None Just match this AS_PATH of 100 100 i Ip route 0.0.0.0 0.0.0.0 192.168.23.3 The GW configuration is as follows: Manually modify the hop count of RIP . First configure matching routes Vlan 10 Half-life: 15 minutes BGP PA can measure or traffic statistics on IP traffic sent by BGP peers. The IGP routes into BGP when the associated Route-map settings Load distribution: 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 (refcount 1) Display has not been loaded into the RIB in the BGP routing, and why not loaded Rule verification (the AS number in the federation does not participate in the AS_PATH length calculation) 2 : Reponse message, send all or part of its routing information, a Response Origin IGP, metric 0, localpref 100, valid, internal Device ID r >i1.1.1.0/24 This is the ICMP redirect message sent by R1 to R3 . Note that the Gateway address field in the header is filled with the next hop IP that is closer to the destination than the destination . Router ospf1 Path Reduce network migration time without disconnecting existing connections, and do not need to change device BGP configuration in large batches Switch(config)# interface vlan 255 The buddy first introduced the above network environment. This Nima is a fairly classic case. OR1 and OR2 are the egress routers of the network, which are respectively connected to the egress lines of Netcom and telecommunications. PAT is implemented on both egress routers , so that intranet users can access the extranet. In addition to OR1 , Modify AS_PATH with route-map The route originated from the local (such as the local network , or aggregate ), that is,ccnp switch student guide, the next hop is 0.0.0.0 ( in the BGP table , the current path) Determine if the frame has a VLAN tag . Integrated pvst functionality and publicization 100 Range character example: Last update from 192.168.101.10 on Serial0/0, 00:12:46 ago Routing Descriptor Blocks: The decision process of BGP is to use the local routing policy for the routes in ajd-RIBs-IN , and put the selected or modified routes into Loc-RIB and 8.3.4 Questions 104 These two attributes are used to prevent ringing within the federation and member AS . By the original impact of routing attributes Adding the summary-only parameter will only pass the summary route, and the detail route will be suppressed. The summary route generated in this case will lose the AS_PATH attribute of the underlying detail route , so there may be some hidden dangers. The WEIGHT attribute is a CISCO private attribute. The scope is this router (not passed), the value is not included in the update Match ip address prefix-list 1 RIP-2 RIPv2 uses multicast update PVST+ Traffic share 1 Configuration example (allocating community for routing ): 200 Each AS has an identification number ranging from 1 to 65535 , of which 64512 to 65535 are reserved for private use. Detect the reachability of the next hop, the default is off The router uses this information to construct a new Layer 2 header for the data frame and then forwards the message to the outbound interface pointing to the next hop. Bibliography 110 Network 192.168.12.2 0.0.0.0 area 0 Tunnel Tunnel interface The GW configuration is as follows: Run the switchport port-security mac-address command to configure a static security address entry. s> 172.16.1.0/24 Access-list 1 permit 192.168.1.0 MED attributes for routes published to the federation are retained throughout the federation Ip route 172.16.0.0 255.255.0.0 192.168.23.3 After the command is configured on the interface, the routing table is not updated periodically in this direction, but the update is triggered. The routing table update will be minimal , including only the initial exchange information of the routing table and the updated information when the routing table changes. This command is only valid on the serial link and must be configured at both ends of the link to produce an effect.
