A. R1 summarizes the 10.1.1.0/24 subnet to 10.0.0.0/8 when it sends its RIPv1 routing updates to R2. R2 summarizes the 10.2.2.0/24 subnet to 10.0.0.0/8 when it sends its RIPv1 routing updates to R1.
B. To support this topology, R1 and R2 must be configured so that RIPv1 auto-summary is disabled.
C. R1 sends information about the 10.1.1.0/24 subnet when it sends its RIPv1 routing updates to R2. R2 sends information about the 10.2.2.0/24 subnet when it sends its RIPv1 routing updates to R1.
Example of RIPv1 update from R1 to R2:RIP: build update entriesnetwork 10.1.1.0/24 metric 1
D. Hosts on the 10.1.1.0/24 subnet are unable to communicate with hosts on the 10.2.2.0/24 subnet.
