For the above problems in the related art, the following further describes, by taking the first device as a server, with reference to specific alternative embodiments, where the following alternative embodiments combine the above alternative embodiments and alternative implementations thereof.
This optional embodiment provides a method for reestablishing a BMP session after the BMP session is quickly broken, which can be conveniently operated and quickly establish a BMP session in a short time, and includes: if the whole BMP case is enabled again after being disabled, all BMP sessions are allowed to build a chain again; or a BMP session forces DOWN and then lets it re-establish the link.
FIG. 7 is a diagram illustrating BMP chain establishment in accordance with a preferred embodiment of the present invention, as shown in FIG. 7, after one end of BMP session is DOWN, the other end is not aware of it and still in the UP state for some reason; according to the related protocol, a DOWN party initiates a connection request, and an UP end does not respond to the link establishment request after receiving the link establishment request; this results in the BMP sessions at both ends not being able to communicate. With the present alternative embodiment, a mandatory measure may be used to change the BMP session of the UP to the DOWN, and then the BMP connection is established according to the flow of fig. 1. For example, if only a certain BMP is needed to build a chain on the device, the state of the BMP is DOWN, and the other end of the BMP is UP, at this time, we can take a mandatory measure for the UP BMP session, for example, use a configuration command to change the state of the BMP session to DOWN, as shown in fig. 7, and then build a chain according to the normal BMP.
Fig. 8 is a diagram illustrating BMP establishment according to a preferred embodiment of the present invention, where, as shown in fig. 8, if there are multiple BMP sessions on the first device, the state is all UP, or some of the BMP sessions are UP state and some are DOWN state, but the BMP sessions of one or more second devices connected to the first device are all DOWN; it should be noted that the first device may be a server or other devices, and may be configured to force the BMP instance to be "disabled", and all BMP sessions on the first device are converted into DOWN, and then the BMP instance is enabled again, so that the BMP session is re-linked.
In summary, if one end of the BMP sessions is UP and the other end of the BMP sessions is DOWN under an abnormal condition, the BMP connections can be established conveniently and quickly by the above method, and efficiency is improved.
