ccnp switch gns3

The AS_PATH can be controlled by the policy to affect the route selection. For example, if you want R3 to reach the 1.1.1.0 network priority R1 , you can make a policy on R2 , as follows: Exchange network security Ip arp inspection trust Network 5.5.5.5 0.0.0.0 area 0 Below is an example: Via 10.1.13.3, FastEthernet1/0, 0 dependencies Experimental phenomena: Vlan 100 Hardware-address hardware-address type Wherein SW1 is as follows: Name server R2(config)#router ospf 1 Update it; however, it does not send its secondary address 11.0.0.0 segment from fast0/0 to R1 (unless the split horizon is turned off). MED At this time , the policy is used for R4 on R1 , and the route AS_PATH of 10.0 is inserted into the AS number of 100 100 , and R5 is preferably R3 . Why on R5 will select R3 , through experimental results, where R5 received two routes, one from the Federal EBGP neighbors, one from EBGP neighbors,ccnp switch gns3, the final preferred EBGP routing neighbors. Network 172.16.10.0 mask 255.255.255.0 Vlan 100 Protocol overview Advertised to update-groups: 1 It is recognized that the attributes must be followed to describe the sequence of AS numbers that must pass through the target network . The most important role is anti-ring. If the BGP speaker finds that its AS number appears in the AS_PATH of the received BGP route update , it indicates that there may be a routing loop, and the routing update is ignored. Another important role is that in the BGP routing, as the measurement of the AS hop count, of course, the fewer ASs included in the AS_PATH , indicating closer to the destination.
