PROTOCOL 标准Add a standard community-list entry Each routing table entry must include at least the following three items: In the above example, the phenomenon we mentioned, R4 will know the route from OSPF and RIP to 192.168.1.0/24 , and finally R4 will choose OSPF route. This is a phenomenon we don't want to see in this environment, because it creates a sub-optimal path. The AD values ​​for several common routing protocols are listed below: Define set action Match ip add pre 1 It does not modify the original data frames, the processing efficiency than 802.1Q higher 3.3.3.3 Switch(config-if)# switchport mode encapsulation {dot1q | ISL} The data is two-way. When considering traffic, pay attention to the round trip of traffic. Two-way re-release of OSPF and RIP How to judge whether there is arp spoofing in the intranet Configuring BGP Federal Ip arp inspection vlan 100 logging acl-match none Confirmation of TCA ( MSB set) to the previous switch. When the root receives the TC , it sends the TCA back to the original sending switch and sends the TC ( LSA set) to all bridges . Switch receives ROOT issued to TC after, will MAC aging time address table is reduced to 15s Path 8 bits After 10.30.0 is passed to R3 , since the RIP updated subnet and the R3 interface subnet belong to the same main class network, R3 receives the update, and uses the interface mask as the mask of the RIP route, so the R3 routing table The route loaded in is: 10.1.20.0/24 Determine if the frame has a VLAN tag . Origin IGP, metric 0, localpref 100, valid, internal, best Originator: 1.1.1.1, Cluster list: 2.2.2.2 If there is no tag , mark the PVID of the Access port and proceed to the next step. Router ospf 1 Router bgp 100 Manual network through BGP , which originated from IGP , because BGP network must guarantee the network Router(config-router)# 65 Used in route-map , when some of the matching entry, and using the set command, the route-map used in a neighbor (e.g., out time direction), then to update the route to a neighbor, the BGP of MED properties will Inherit the metric value of these routes in the local IGP Neighbor 1.1.1.1 remote-as 123 Redistribute routes to the protocol In the federal scope, the member AS number is pushed into the AS_PATH , but not published outside the federation,ccnp route 300-101 kevin wallace, and the AS_PATH of TYPE3 , 4 is used . The EBGP route should be better. I saw R5 and went to see R3 : Redistribute local direct connection network segment into BGP , MED value is 0 ; redistribute local static route into BGP , MED value is 0 8 bits 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 .
