Final answer:
RIPv2 does not summarize routes by default; unlike RIPv1, route summarization in RIPv2 requires manual configuration.
Step-by-step explanation:
Does RIPv2 summarize routes by default? The answer is False. Routing Information Protocol version 2 (RIPv2) does not perform automatic summarization by default; this is a change from its predecessor, RIPv1, which did automatically summarize at network boundaries.
RIPv2, while it still supports route summarization, now requires manual configuration to summarize routes. This gives network administrators greater control over routing table size and network traffic but requires a clear understanding of the network's topology to configure summarization properly.
