- C. iBGP full mesh requirement does not dictate any specific network topology.
- D. iBGP does not work on a ring network topology even with an underlying IGP.
Answer: C
Explanation:
iBGP peers can be multiple hops away. not like eBGP that needs direct connection (or ebgp-multihop defined). thus, only IP connectivity between two peers is required for an adjacency to form.
