Consider the mixed IPv4/IPv6 network shown below, where an IPv4 tunnel exists between IPv6 routers B and E. Suppose that IPv6 router A sends a datagram to IPv6 router F. IPv6 datagrams are shown in blue; the IPv4 datagram is in red (containing the encapsulated IPv6 datagram in blue). Answer the questions below. A IPv6 (a) B IPv6/v4 C IPv4 (b) D IPv4 E IPv6/v4 (c) F IPv6 a. At point (b), the larger (red, encapsulating) datagram has an IP version field of. b. At point (b), the larger (red, encapsulating) datagram has a source IP address of. c. At point (b), the larger (red, encapsulating) datagram has a destination IP address of d. At point (b), the smaller (blue, encapsulated) datagram has a source IP address of. e. At point (b), the smaller (blue, encapsulated) datagram has an IP version field of Activate Wi
