During a network audit, it was discovered that a particular subnet $(10\mathrm{.}0\mathrm{.}5\mathrm{.}0/24)$ was not reachable from certain parts of the organization's RIP$-$based network. The network consists of multiple routers, with Router E directly connected to the $10\mathrm{.}0\mathrm{.}5\mathrm{.}0/24$ subnet.

The audit revealed that Router E is correctly advertising the subnet in its RIP updates.

What could be the reason for the reachability issue?

answer

There is a hop count greater than $15$ between some routers and Router E$.$

RIP updates are being sent too frequently, causing network congestion.

The subnet mask for the $10\mathrm{.}0\mathrm{.}5\mathrm{.}0/24$ network is incorrectly configured on Router E$.$

Router E is not configured to accept RIP updates.
