After receiving B , it judges whether its own resources are sufficient (that is, whether too many connections are established). If it is enough, it returns a confirmation message containing the SAP value identifying the connection . Match ip address 1 TCAM table Configure native VTP mode Route tag 13 Only when the update message is sent to another AS when, the BGP router before its AS number append AS_PATH in. This sentence also implies another meaning, that is, if you want to modify the AS_PATH attribute, you must execute the policy on the AS border router. IP routing table ( IP Routing the Table ) Access-list 2 permit 172.16.20.0 route-map BGP2OSPF permit 10 Route-map usage scenario SW1#show int trunk R4 on the show ip bgp 172.16.0.0 VLAN 15 bits with the current 10 th, then the support up to 2 of the 10 power = 1024 th VLAN The 802.1Q Tag contains 4 fields, which have the following meanings: Experiment 1 Vlan range R1(config-router)#distribute-list 1 in ? // All interfaces Neighbor 10.1.23.3 local-as 201 no-prepend replace-as Metric Milne 's packet was sent to Roo because he learned the wrong one. One point and one asterisk, match all, any The lower the value is set, the higher the protection level for the CPU . This value takes effect before and after the penalty action occurs. Of course, this value cannot be set too low. At least the legal traffic must be processed. Generally less than 1000 is almost the same. Suppress-map unsuppress-map advertise-map inject-map LOCAL-PREFERENCE Network 192.168.10.0 0.0.0.255 area 1 Switch(config)# ip default-gateway 192.168.255.254 !! Set the gateway for the access switch itself Major Points With object tracking, PBR can be more flexible, and can make decisions based on ICMP , HTTP , the presence or absence of a route in the routing table, and the up/down of the interface . The MAC address in the ARP table is all zero ( Windows host) or " No completed" (network device) Host address. Use the err-disable command to modify the duration of the err-diasable state. The default is 300S. Also a route prefix may carry multiple community to form a list,ccnp routing and switching 300-115 pdf, 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. / / This is used to delete the no-export attribute, is a list of commands Metric After receiving this poisoning message, B erases 10.4.0.0 from the routing table, but it still exists in the rip database , the status is possible down , the garbage collection time ( Garbage colletion CISCO default 60S ), the route is from B. The database is erased. 345 ; R3 has a federated IBGP neighbor R4 . The Layer 2 interface contains access mode and trunk mode that we are very familiar with . All physical interfaces of the switch are Layer 2 interfaces by default, which is switchport . Static route associated with the outbound interface For ISL packages, MTU=1548 ( explained below ) Command When a BGP route is sent from the group members of the cluster to the RR , RR The default COST value of all ports on the switch will increase by 3000 , so that the port of the switch is not elected as the designated port. Management VLAN in a Layer 3 switch environment If R2 on ip route 1.1.1.0 255.255.255.0 null0 , this time there is no routing table OSPF of 1.1.1.0 routing the unsuccessful thus re-release, so R3 can not learn the 1.1.1.0/24 route; Network without mask is a class declaration, plus the mask is no class declaration Ip route 2.2.2.0 255.255.255.0 192.168.13.1 Define matching criteria The EBGP route should be better. I saw R5 and went to see R3 : The secondary VLAN is mapped to the SVI interface of the primary VLAN , allowing for Layer 3 switching of pVLAN ingress traffic. Each message contains a BGP message header. The header of the BGP message is as follows: Tool overview 62 Switch(config-if)# ip address 192.168.255.254 255.255.255.0 About PBR R1 announces 1.1.1.0 into BGP , and R2 learns these two routes from 10.1.12.1 and 10.2.12.1 respectively. Routing, accept updates. R1(config-route-map)# match ip address prefix-list list1 After the test is verified, (in the case that the basic configuration of BGP is correct) , the network segments of the looback interface of R1 and R2 are learned by static routes or dynamic routes. The establishment of BGP neighbor relationships is fine , but if both ends use the default. If the routes refer to each other, the BGP neighbor relationship cannot be established. This is for the purpose of anti-ring. When using static, the default is ok.
