Network and Connectivity
Updated on 2022-09-14 GMT+08:00
Network
If the connection fails to work properly after you have created a virtual interface and used it to connect your environment to Huawei Cloud, perform the following steps to locate the fault:
- Verify that the local gateway can be pinged from the remote gateway and that the VLAN of the intermediate device on the physical network configured correctly.
- Verify that IP addresses of the local and remote gateways are in the same CIDR block and configured on the VLAN sub-interfaces.
- If static routing is used, verify that the next hop or outbound interface of the static route is configured correctly.
- If BGP routing is used, verify that the BGP ASN, BGP MD5 authentication key, and BGP peer IP address are correctly configured. BGP ASNs on both gateways must be different.
- If BGP routing is used, verify there are not more than 100 BGP routes advertised through the virtual interface. If there are more than 100, excess BGP routes will not be received.
- If BGP routing is used, verify that the rule for prohibiting TCP port 179 or large digital temporary TCP port connection is not configured.
Connectivity
If the network connectivity is abnormal after you have connected the leased line to the endpoint device, perform the following steps to locate the fault:
- Verify that the network device is connected correctly, auto-negotiation is disabled for the optical port, and the port speed and full-duplex mode are configured manually.
- Verify that optical signals can be normally transmitted and received.
