Quidway S3500 Series Ethernet Switches
Fault 2: BGP route cannot be advertised correctly after importing route of IGP with the
command network.
Troubleshooting: Route imported by command network should be same as a route in
current routing table, which should include destination segment and mask. Route
covering large network segment cannot be imported. For example, route 10.1.1.0/24
can be imported, while 10.0.0.0/8 may cause error.
