MultiRecv<br />

The route entries starting with [RIP/100] are those learned from RIP. The router has<br />

learned six routes from RIP:<br />

• 10.0.1.0/24, 10.0.16.0/24, and 10.0.24.0/24, which are subnetworks<br />

• 192.168.0.1/32 and 192.168.2.1./32, which are router loopback addresses<br />

• The RIP Version 2 multicast address<br />

The value of 100 in the brackets is the JUNOS default value for the RIP administrative<br />

distance, also called the preference, which is used to select which route is<br />

installed in the forwarding table when several protocols calculate routes to the same<br />

destination. You can change the preference value by configuring the preference<br />

statement for the RIP group. The numbers following the brackets show how long the<br />

routing table has known about the route. The metric value (either 1 or 2) indicates<br />

the distance (number of hops) to this address. Understanding the routing table is discussed<br />

in more detail in Recipe 8.1.<br />

You might find it strange that a multicast address, 224.0.0.9/32, is present in the<br />

inet.0 routing table, which is the unicast routing table. This is simply a result of a<br />

JUNOS design decision. Instead of establishing a separate routing table for the few<br />

multicast routes used by routing protocols, which are well-known addresses, the<br />

JUNOS software places these routes in the unicast routing table.<br />
