Data Connection MIBs

Data Connection Ltd (DC) isn't a hardware vendor — it licenses a routing-protocol software stack that other router/switch vendors embed in their own products — so its MIBs here cover BGP peering, IS-IS adjacencies and link-state database, and the routing table manager (RTM) that handles route redistribution, plus a shared DC-MASTER-TC module of textual conventions the others depend on. Because DC's stack runs inside other vendors' hardware, the device behind these MIBs is whatever router or route server happens to embed the DC routing engine, not a Data Connection-branded box. Come here only if you know your router/switch uses an embedded Data Connection routing stack and need its BGP/IS-IS/RTM OIDs specifically, rather than the vendor's own native routing MIBs. With just 4 modules, check DC-MASTER-TC first since the other three all depend on its shared conventions.
