Configure IRMP Basic Function Example

Network Requirements

The IRMP operates between Device1 and Device2, establishing the neighbor and interacting the route.

Configuration Steps

Step 1: Configure the IP address of the interfaces. (Omitted)

Step 2: Configure the IRMP.

#Configure Device1.

Device1#configure terminal
Device1(config)#router irmp 100
Device1(config-irmp)#network 1.0.0.0 0.0.0.255
Device1(config-irmp)#network 100.0.0.0 0.0.0.255
Device1(config-irmp)#exit

#Configure Device2.

Device2#configure terminal
Device2(config)#router irmp 100
Device2(config-irmp)#network 1.0.0.0 0.0.0.255
Device2(config-irmp)#network 200.0.0.0 0.0.0.255
Device2(config-irmp)#exit

Step 3: Check the result.

#View the IRMP neighbor information of Device1.

Device1#show ip irmp neighbor  
IP-IRMP neighbors for process 100 Total neighbor 1 
Address     Interface            Hold(s) Uptime   SeqNum   Srtt(ms) Rto(s) 
1.0.0.2     gigabitethernet1     14      00:00:47 7        0         2

#View the IRMP neighbor information of Device2.

Device2#show ip irmp neighbor  
IP-IRMP neighbors for process 100 Total neighbor 1 
Address     Interface            Hold(s) Uptime   SeqNum   Srtt(ms) Rto(s) 
1.0.0.1     gigabitethernet0     11      00:00:43 4        3920     4

It can be viewed that the IRMP neighbor is established between Device1 and Device2I
