1. Question: When dhcp v6 is configured, the connected terminal will automatically obtain an ipv6 address. How can I cancel it?
Answer: ipv6 nd suppress-ra can turn off the routing function.
2. Question: Server NIC active/standby mode, how is the switch configured?
Answer: When the server and the two NICs are connected to the switch, the switch interface only needs to be configured with a trunk. It does not need to be aggregated.
3. Question: What is the priority of the ACL call?
Answer: The priority of the acl global call is greater than the priority of the interface call.
4. Question: What are the precautions for optical module docking?
Answer: The optical module rate cannot be modified. Only the switch interface rate can be modified. The switch interface is backward compatible and the optical modules are not backward compatible.
5. Question: The policy route calls route-map. Can the match int+ interface be used in the match field?
Answer: The match-map interface of the route-map is used when the route is redistributed. It matches the outbound interface. When the route-map is invoked using policy routing, the match field cannot be added.
6. Question: The policy routing of the switch sets two next hops. Can it identify the two next hops? One can't get through, go one?
Answer: The policy routing of the switch defaults to the redundant backup mode. In this case, if the first one is identified, the first one is taken. If the first one is not matched, the policy routing is skipped. This mode can be changed to load balancing. The way to achieve the first feature of the user can not go through the second.
The command is: ip policy load-balance
7. Question: Is policy routing invoked in the VRF, is the priority higher than the normal static route?
Answer: In VRF, policy routing has a lower priority than static, default routing and vice versa.
8. Question: After the PBR is configured on the SVI interface, the policy routing test using the SVI interface address as the source address on the switch is unsuccessful.
The test of the policy route on the switch on which the policy route is configured is not successful because it does not pass a match for the policy route at this time.
9. Question: How does the switch do it from source out?
Answer: It can be partially implemented in the way of policy routing (PBR) and the switch itself cannot do the source in and out.
10. Question: Does the policy route do not take effect after the call?
Answer: Check the next hop configuration, set next-hop is the next hop to modify BGP. For IGP route does not take effect, IGP route is using set ip next-hop.
