you can disable filtering to the received global routing information

Parameter
None
Description
Using the host-route command, you can control the RIP to accept the host route.
Using the undo host-route command, you can reject the host route.
By default, router accepts the host route.
In some special cases, RIP receives a great number of host routes in the same
network segment. These routes cannot help the path searching much but occupy
a lot of resources. In this case, the undo host-route command can be used to
reject host routes.
Example
Configure RIP to reject a host route.
