Neighbor TCP / IP Volume II of this note contains TCPIP Routing Volume BGP almost all the content parts, and a detailed expansion Although the network devices are in the same subnet, they belong to different pVlans , and communication between pVlans must be implemented through the default gateway. If both are open FastEthernet0/0 Ip community-list ? 10.1.25.2 Mode The route obtained by the BGP speaker from IBGP is not advertised to its IBGP neighbors (avoiding loops and splitting horizontally; except for the case of route RR ) Enabled by default, if an interface DOWN up, BGP answer immediately suspended. Basic knowledge point Federal related features: Switch(config)# spanning-tree vlan vlan-id priority pri Interface loopback2 BGP is designed to AS transfer routes between, so it is actually a hop AS . Supplementary explanation of the role of the as_set keyword: Origin IGP, metric 0, localpref 100, valid, external, atomic-aggregate , best WWW and SMTP belong to the Isalated VLAN ,ine ccnp route workbook 2015, so they cannot access each other; WWW and SMTP servers can only communicate with the promiscuous port, that is, with the router. *>i100.0.2.0/24 Note that atomic_aggregate is a recognized free decision attribute. Let's understand: Enhanced Interior Gateway Routing Protocol (EIGRP) ISO IS-IS Elect a root port on each non-root bridge 00:00:54 Port-Security supports activation on the trunk configured as follows IP address Decision making Ip dhcp relay information trusted Router bgp 345 Ip route 0.0.0.0 0.0.0.0 192.168.12.1 Neighbor 3.3.3.3 remote-as 345 Access-list 1 permit 172.16.10.0 The EBGP route is set to a small AD value of 20 . So looking at the above picture, two VLANs are created on the Layer 3 switch : 10 and 20 , and the addresses of the SVIs of the two VLANs are assigned as the user gateways of the respective VLANs , so that the routing table of the switch is There are routes for two VLAN segments. Then, when the two VLANs need to communicate with each other, the user of VLAN 10 will drop the data to his own gateway, that is , the SVI of VLAN 10. After the data arrives at SVI10 , the Layer 3 switch looks up the table and finds that the destination is the network segment where VLAN 20 is located. Throw the data out of VLAN 20 and eventually reach the destination VLAN 20 of the PC .
