Routing Information Protocol | 883
Figure 42-3 shows an example of the RIP configuration after the ROUTER RIP mode version command is
set to RIPv2. When the ROUTER RIP mode
version command is set, the interface (GigabitEthernet 0/0)
participating in the RIP process is also set to send and receive RIPv2.
Figure 42-3. show ip protocols Command Example
To configure the interfaces to send or receive different RIP versions from the RIP version configured
globally, use either of the following commands in the INTERFACE mode:
To configure an interface to receive or send both versions of RIP, include 1 and 2 in the command syntax.
Figure 42-4 displays the command syntax for sending both RIPv1 and RIPv2 and receiving only RIPv2.
Figure 42-4. Configuring an interface to send both versions of RIP
The show ip protocols command example Figure 42-5 confirms that both versions are sent out that
interface. This interface no longer sends and receives the same RIP versions as FTOS does globally.
Command Syntax Command Mode Purpose
ip rip receive version [1] [2] INTERFACE Set the RIP version(s) received on that interface.
ip rip send version [1] [2] INTERFACE Set the RIP version(s) sent out on that interface.
