For details on the related fields of the BGP table, see the show section of the BGP Configuration section of this document. Note that this address is the address used by the neighbor to establish a BGP neighbor relationship. Gratuitous ARP , the free ARP is a special ARP Request/response message, that is, the Sender IP is the same as the Target IP (usually used for IP collision detection). Network xxx mask yyy route-map zzz Vlans allowed on trunk The route closest to BGP NEXT_HOP is preferred , and the route is the route with the smallest IGP metric to the next hop router . Network 10.1.34.0 0.0.0.255 area 0 Access-list 2 permit 192.168.2.0 0.0.0.255 route-map PBR permit 10 Assuming the environment is like this, R1 re-releases A route into OSPF , then R2 will learn this OE2 in its own OSPF process 1 . Weight 10.1.23.2 from 10.1.23.2 (10.1.23.2) Path control 77 200 Bgp dampening BGP supports MD5 authentication. To enable MD5 authentication on the TCP connection between BGP peers , use the following command: Origin IGP, metric 0, localpref 100, valid, internal, best Originator: 1.1.1.1, Cluster list: 2.2.2.2 This has already been said before. 1,10,20,30 r route is not loaded into the RIB table, for example due to AD values, etc. Discard the illegal ARP packet, the switch will discard the illegal ARP after log R3 receives two routes, respectively carrying the community attribute as above. Now, we only want to delete the no-export attribute of the 11 route . 159 220 , 91 70 Route 2 : the AS_PATH : 500 the MED : 100 Internal RouterID : 172.16.8.1 Note that at this moment, although SW1 trims the traffic of vlan10 on the fa0/20 port , the fa0/20 port of SW3 does still release the traffic, but in any case, the PCs cannot communicate with each other. Demonstrate, know the role of allowed vlan . Of course, this is the way to manually trim. After R2 show run , I found: Enabled by default, if an interface DOWN up, BGP answer immediately suspended. Match as-path 1 200 ? Note: RR only creates or updates CLUSTER_LIST when the route is reflected . In the following cases,ccnp route price, the RR does not create this attribute: Internet (well-known community) Switch(config)# vlan 255 Switch(config)# interface fast0/1 The switches at both ends of the trunk need to use the same trunk protocol. Auto: passively wait for other side to ask Set ip next-hop 11.1.1.2 exit R3 announces 192.168.1.0 , 2.0 , and sets the community attribute of 1.0 to no-adv. Update behavior AS_Sequence is well understood. In the case where the above figure does not make any policy, the type of AS_PATH carried by the BGP route delivered to R4 is AS_Sequence . This is an ordered list of AS numbers. When R4 receives the route update, AS_PATH is 300,100 , Address family AS Hops 1 Transparent mode VTP configuration revision number is always 0 Then according to our thinking, on the R4 should be able to see the choice of 100.0.1.0 is R3 is 3.3.3.3 , go to In the R3 , the route AS_PATH learned from R2 about 1.1.1.0 will become " 6666 200 i ", because R3 receives 1.1.1.0 (Note that in the actual environment, the situation may be quite different). 10.1.12.2 As mentioned above, the secure address entry formed by the dynamically learned MAC address of the interface will lose the secure address entries formed by the dynamically learned MAC after the interface is up/down , but all interfaces are used. The switchport port-security mac-address is manually configured and the workload is too large. Therefore, this sticky mac address allows us to turn these dynamically learned MACs into a "sticky state " . It can be simply understood that I will learn dynamically, and after I learn, I will glue you up to form a "static". "(Effectively SecureSticky ) entries.
