Step 7
show ip arp
Use this command to verify that ARP is enabled, for example:
Router# show ip arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 20.1.1.1 - 0050.a2de.7055 ARPA Ethernet3/1
Internet 10.0.18.171 - 0050.a2de.7054 ARPA Ethernet3/0
Step 8
show ip arp vrf vrf-name
Use this command to verify that the VRF named “red” is assigned to the correct IP address and
interfaces, for example:
interfaces, for example:
Router# show ip arp vrf red
Protocol Address Age (min) Hardware Addr Type Interface
Internet 1.1.1.1 - 0050.a2de.7055 ARPA Ethernet3/1
Internet 2.1.1.1 - 0050.a2de.7056 ARPA Ethernet3/2
Use the ping command from IP address 1.1.1.2 to IP address 1.1.1.1 and then the show ip arp vrf red
command to verify the ARP entry of 1.1.1.2 in VRF red, for example:

Router# show ip arp vrf red
Protocol Address Age (min) Hardware Addr Type Interface

Internet 2.1.1.1 - 0050.a2de.7056 ARPA Ethernet3/2
A ping from IP address 2.1.1.1 and IP address 2.1.1.2 are also good. This creates an ARP entry of 2.1.1.2
in VRF red as shown below using the show ip arp vrf red command.
