The MPLS LDP autoconfiguration enables LDP on interfaces associated with an IGP instance. Which two IGPs support this feature?

MPLS LDP autoconfiguration simplifies LDP deployment by automatically enabling LDP on interfaces participating in a specified Interior Gateway Protocol (IGP). This feature is specifically designed to integrate with link-state routing protocols that maintain a comprehensive topology database, making OSPF and IS-IS the supported IGPs. These protocols provide the necessary link-state information for LDP to establish neighbor adjacencies and exchange label mappings effectively across the network. BGP is an exterior gateway protocol and does not provide the internal topology information required for LDP autoconfiguration. RIP and EIGRP are distance-vector protocols and do not have the same detailed link-state database as OSPF or IS-IS, thus they are not supported for LDP autoconfiguration.
