Huawei route switch Fault Analysis

MP is to bind the PPP of multiple physical links to the same logical port. It aims to increase the bandwidth of the link, as long as the physical link that supports PPP can enable MP, bind each other to the Dialer port of the same logical port. MP allows fragment processing of packets at the IP and other network layers, transmitting the fragmented packets through multiple links, and arriving at the same destination, in order to summarize the bandwidth of all links.

1. Enable the dynamic routing protocol on the router to dynamically learn the network topology. This problem occurs when an unauthorized network device accesses the network and releases a route protocol update, it may cause devices in the network to dynamically generate incorrect route entries, resulting in packet loss or being routed to a wrong place. At this time, we need to use PBR.

2. PBR is a flexible packet forwarding mechanism. By applying a policy route on the router, the router determines how to process the router data packets based on the route ing, the route ing determines the next hop forwarding router of a data packet.

3. to apply a policy route on a vro, you must specify the route ing used by the policy route and create a route ing. A route ing consists of multiple policies, each policy defines one or more matching rules and corresponding operations.

4. After an interface applies a policy route, all packets received by the interface will be checked. packets that do not conform to the rules defined in the route ing will be forwarded by normal routes, data packets that comply with the routing ing policy are processed according to the operation defined in the policy.

5. Assume that the E0/0 port of the vro is used as the gateway of the internal network and the address is 200.1.1.1. There is a WEB server in the internal network with the address 200.1.1.100 and one user computer in the same network segment as the WEB, there is a remote user in the external network with the IP address 199.1.1.100, which allows remote users to access the WEB server but not the computers of internal users.

Vi. configuration steps

1. Router (config) # interface Ethernet0/0;

2. Router (config-if) # ip address 200.1.1.1 255.255.255.0;

3. Router (config-if) # exit;

4. Router (config) # interface Ethernet0/1;

5. Router (config-if) # ip address 199.1.1.1 255.255.255.0;

6. Router (config-if) # exit.

VII. Test

1. Router # ping 200.1.1.100;

2. Type escape sequence to abort .;

3. Sending 5, 100-byte ICMP Echos to 200.1.1.100, timeout is 2 seconds;

4 ,!!!!!;

5. Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/4 MS;

6. Router # ping 200.1.1.10;

7. Type escape sequence to abort;

8. Sending 5, 100-byte ICMP Echos to 200.1.1.10, timeout is 2 seconds;

9 ,!!!!!;

10. Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 MS;

11. Router # ping 199.1.1.100;

12. Type escape sequence to abort;

13. Sending 5, 100-byte ICMP Echos to 199.1.1.100, timeout is 2 seconds;

14 ,!!!!!;

15. Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/4 ms.

Through the above steps, our goal is achieved. Note that the PPP physical link initiates an MP request after the common LCP parameters are negotiated. If the other link supports the MP, in addition, if a correct response is provided, it is bound to the logical port together with other physical links for NCP negotiation. If the negotiation succeeds, all the physical links of MP will use the network address of the same logical port.
