Abstract: A Section Route (SR) information obtainment method and an SR network establishment method are described. The SR information obtainment method includes: notifying each other the SR information among the nodes in an Autonomous System (AS) domain in the SR domain via Interior Gateway Protocol (IGP); notifying and exchanging the SR information among the cross-domain nodes in the SR domain, or among the border nodes and the cross-domain nodes in the AS domain, via Multi-Protocol Border Gateway Protocol (MP-BGP).
