OpenSLP implements SLPv2, but NetIQ SLP (NDSslp) on Linux and Windows platforms implements SLPv1.
SLPv1 UAs do not receive replies from SLPv2 SAs, and SLPv2 UAs do not receive replies from SLPv1 SAs. That is, the clients with OpenSLP cannot see trees with NDSslp. Similarly, the clients with NDSslp cannot see trees with OpenSLP. For SLPv1 and SLPv2 to interact, you need to configure a DA that is running SLPv2.OES Linux ships with OpenSLP. However, eDirectory installed other Linux platforms, such as Red Hat Linux, might use NDSslp, which is shipped with eDirectory. Because of interoperability issues with the two versions of SLP, a tree advertised via OpenSLP multicast might not be visible to NDSslp and vice versa. To overcome this problem, you need to configure a DA that runs OpenSLP.
