Abstrakt: For a connected graph G = (V (G), E(G)), a subset F ⊂ V (G) is called an Rk-vertex-cut if G- F is disconnected and each vertex u ∊ V (G) - F has at least k neighbors in G - F. The cardinality of a minimum Rk-vertex-cut of G is the Rk-vertex-connectivity and is denoted by kk (G). The conditional connectivity is a new measure to study the fault tolerance of network structures beyond connectivity. In this paper, we study R1-vertex-connectivity and R2-vertex-connectivity of Cayley graphs generated by 2-trees T2,n which are denoted by KTn and show that K1(KTn) 4n-8 k1( ) = - for n ⩾ 4; K 2 (KTn) = 8n -22 for n ⩾ 6.
