When using V1R3 (5.21/36.13.45) software to enable IP over DCC using the navigator to enable OSPF routing, no command exist to enable OSPF. However, using same software for SSQ1CXL and SCC card in OSN3500 and OSN1500A/B have the command to enable OSPF. E.g. cm-set-ospf, cm-set-ospf-import, etc.
For OSN1500A/B if using SSQ2CXL cards or OSN3500 using GSCC, upgrade it to NE software such as V1R6 (5.21/36.16.12) which have support of OSPF for SSQ2CXL cards and GSCC card.
Due to the physical capability of SSQ2CXL to support ASON, V1R3 software doesn't give command to enable OSPF. Whereas controller boards that can't support ASON physically can use commands to enable OSPF. E.g. SSQ1CXL and SCC with V1R3 software
When planning to use IP over DCC with OSPF routing, it is best to ensure all controllers e.g. GSCC, SCC, SSQ1CXL, SSQ2CXL, etc.. in the network supports all the require features to turn on essential functions which needs to deploy IP Over DCC.
