Hi,
Probably the dump is wrong:
RIP-2 is a type of classless routing protocol. A RIP-2 packet carries subnet mask information. Deploying a RIP-2 network saves IP addresses. On a network where the IP addresses of devices are not consecutive, only RIP-2 can be deployed, and RIP-1 cannot be deployed.
RIP-2 features include:
RIP-2 route summarization
RIP-2 authentication mode
Route summarization is enabled in RIP-1 by default, and cannot be manually configured. RIP-2 supports VLSM and CIDR. You can configure route summarization in RIP-2 to improve the flexibility of RIP-2. To broadcast all subnet routes, you can disable route summarization in RIP-2.
