3.2.7 Disabling host route

In some special cases, the router can receive a lot of host routes from the same
segment, and these routes are of little help in route addressing but consume a lot of
network resources. Routers can be configured to reject host routes by using undo
host-route command.
Perform the following configurations in RIP view.
Table 3-7 Disabling host route
Enable receiving host route
Disable receiving host route
By default, the router receives the host route.
3.2.8 RIP-2 Route Aggregation Function
The so-called route aggregation means that different subnet routes in the same natural
network can be aggregated into one natural mask route for transmission when they are
sent to the outside (i.e. other network). Route aggregation can be performed to reduce
the routing traffic on the network as well as to reduce the size of the routing table.
RIP-1 only sends the route with natural mask, that is, it always sends routes in the route
aggregation form. RIP-2 supports subnet mask and classless interdomain routing. To
advertise all the subnet routes, the route aggregation function of RIP-2 can be disabled.
Perform the following configurations in RIP view.
Table 3-8 Route Aggregation Function
Activate the automatic aggregation function of RIP-2
Disable the automatic aggregation function of RIP-2
By default, RIP-2 automatic route summarization is enabled.
3.2.9 Setting RIP-2 Packet Authentication
RIP-1 does not support packet authentication. But when the interface operates RIP-2,
the packet authentication can be configured.
RIP-2 supports two authentication modes: Simple authentication and MD5
authentication. MD5 authentication uses two packet formats: One follows RFC1723
and another one follows the RFC2082.
