Answer 1

On a VLSM network, which mask should you use on point-to-point WAN links in order to reduce the waste of IP addresses? Explanation: A point-to-point link uses only two hosts. A /30, or 255.255.255.252, mask provides two hosts per subnet.

Answer 2

Answer:

A point-to-point link uses only two hosts. A /30, or 255.255.255.252, the mask provides two hosts per subnet.

Explanation:

• A 31-bit subnet mask is often used for an interface that is the endpoint of a point-to-point network. The use of 31-bit subnet masks for IPv4 point-to-point links is described in RFC 3021. Router A is connected via Fast-ethernet 0/0 having IP 192.168
• When it comes to IP subnetting, as you don’t do it every day, it can be confusing and take a while to get back into. In this article, we will cover a certain type of IP subnet mask – the /30 and /32-bit subnet mask – and find how these subnet masks can be very useful when assigning IP addresses to your WAN links to your special router interfaces.
