A . IS - IS is capable of supporting IPv4 and IPv6. B . IS - IS is only capable of supporting IPv4 and CLNS. C . IS - IS routers use ES - IS hellos (ESH) to establish and to maintain neighbor relationships. D . IS - IS routers run the Bellman - Ford algorithm against their LSDBs to pick the best paths. E . Level 1 routers learn about paths within the area of which they are a part. F . Level 2 routers learn about paths both within areas and between areas.
