Sw(config)#vlan 100 [Experiment 1 ] There is a main class route; there is a default route, and the main class route is taken. Routing entry for 192.168.1.0/24 Switch(config-if)# switchport access vlan 10 Switch(config)# interface fast0/2 Switch(config-if)# switchport access vlan 20 EBGP neighbor Router ospf 100 Route-map cisco permit 20 match ip address 2 set metric 10 In the process of double-point bidirectional routing re-release, many problems may occur, such as sub-optimal paths, potential routing loops, etc. This chapter will discuss this model and existing problems in depth. If the currently configured keepalive timer is greater than min ( holdtime ) /3 , then int[min ( holdtime ) /3] 3.3.3.3 basic configuration Non-equivalent load balancing Passing the value of Tag Distribute-list 1 in Recognized as a self-determination attribute. LP is the local priority and is used for Update messages between internal peers ( IBGP ) , but not to other EBGP neighbors. The larger the LP value, the higher the priority. 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. ( Optional non-transitive ) SA sends the original switch MAC of the frame When the previous eight routing principles fail to optimize the optimal route, and the maximum-paths [ibgp] n is configured under the BGP process , and the value of n is 2-6, the equivalent load balancing will be performed. Example 2 : Ip default-gateway 108 Add redundant routing 9 The configuration of R5 is as follows: Modify the default AD value of BGP . The command is as follows: Static route associated with the outbound interface R3 sets the tag when injecting the route. A route-map defined on the interface . In this way, only the PBR action will be performed on the traffic entering the interface . The traffic originating from this device is invalid. / / Interface or protocol Topology change mechanism (delivery) The BGP election routeriID rule is the same as OSPF . The secondary VLAN is mapped to the SVI interface of the primary VLAN , allowing for Layer 3 switching of pVLAN ingress traffic. If you try to activate 8021.X on a port-security interface, you will get an error and the 802.1X function will not open. Refcount 6 Redistribute ospf 3 subnets route-map OSPF3to2 ip default-network The weight of the BGP route generated by the local summary is also 32768. R4#sh ip ro 192.168.1.0 Set comm-list 1 delete Paths: (2 available, best # 2, table Default-IP-Routing-Table) Flag: 0x820 MED attributes for routes published to the federation are retained throughout the federation Exactly the same, except that the list of AS numbers belong to the local Federation AS The problem is similar to that mentioned above. Both R2 and R3 can learn to update the BGP B network segment route from R4 . Suppose R2 republish do first, then B routes will be injected into the OSPF , the finally R3 learned, then R3 ,ccnp switch new questions, the same time from the OSPF and IBGP learned this route, will preferably OSPF , since OSPF is AD smaller. As a result, on R3 , the redistribution of IBGP to OSPF fails because the route of the B network segment is not BGP in the routing table . Furthermore, R3 has been re-released in both directions. Therefore , the route of the B network segment will be re-released back to IBGP . Since then, there may be a series of problems such as sub-optimal paths and loops.
