BGP routing attribute_as path

BGP attributes Routing attributes are specific descriptions of routes. All BGP routing attributes can be divided into the following four categories. Common BGP attribute types are shown in Table 1: Well-known mandatory: All BGP devices can recognize this type of attribute and must exist in Update messages. If such attributes are missing, the routing information […]

BGP path selection–AS_Path

AS_Path attribute The AS_Path attribute records all the AS numbers that a route passes through from the local to the destination address in vector order. When receiving a route, if the device finds that the AS number is in the AS_Path list, it will not receive the route, thus avoiding inter-AS routing loops. When the […]
