Block non-designated ports In R2 opened on loopback interfaces 2.2.2.0/24 , R2 both redistributed RIP into OSPF , they redistribute directly connected into OSPF SW1 still turns on dhcp snooping and inserts option82 Edge port edge ports R1(config-router)# neighbor 10.1.12.2 route-map rp out Aggregate-address summary address suppress-map xxx as-set VLAN IDs of the allowed VLANs when this port is in trunking mode add VLANs to the current list We expect the effect of the above configuration is implemented R1 to 100.0.1.0 routing setting MED = 100 , 2.0 disposed MED = 200 is , while R2 to 100.0.2.0 disposed MED = 100 , 1.0 arranged MED to 100 , respectively, to the respective property The EBGP neighbor takes effect, so the MED attribute will be passed along the route in AS345 and finally arrive at R4 . After the completion, the two PCs can communicate with each other. You must use neighbor in the BGP process to specify the BGP peer . They exchange routing information, as well as related attributes, not link status. VTP Version capable Weight case study Sw1(config-if-range)#switchport trunk encapsulation dot1q The route originated from the local (such as the local network , or aggregate ), that is, the next hop is 0.0.0.0 ( in the BGP table , the current path) INDEX This port is the peer switch source port so the ISL frame is up to 1548bytes ( 1518+26+4 ) Sw1(config-if)#ip address 172.16.10.1 255.255.255.0 Sw1(config-if)#no shu Activate Port-Security on the interface In addition, if there are multiple links between two EBGPs and use their respective Loopback ports as the source , you should also pay attention to the configuration. Ebgp-multihop 2 (because loopback spans two routers, including this one ), and must also refer to static routing to the other's loopback interface. ) Origin IGP, metric 0, localpref 100, valid, internal, best When the router is in the boot mode and the software is upgraded, the ip routing is also closed, so the command will be used when necessary. Neighbor 10.1.12.2 send-community Experiment 1 : Basic experiment We found that although R4 learned these two prefixes through BGP , it is also valid (with * ),ccnp route tutorial, but it is not optimized (not best , no > mark). If it is not optimized, it will not be loaded into the routing table. Then why is this? Note that the next hop of the two routes is 10.1.13.1 , and it is worth noting that the directly connected network segment of 10.1.13.0 is not declared into OSPF by R3 . In other words, R4 goes to the next-hop of the two routes. Unreachable, the next hop is unreachable. Therefore, although the two BGP routes are in the BGP table, they are not best and cannot be loaded into the routing table.
