Chapter 38 Configuring IP Unicast Routing
Configuring Multi-VRF CE
Use the no ip vrf vrf-name global configuration command to delete a VRF and to remove all interfaces
from it. Use the no ip vrf forwarding interface configuration command to remove an interface from the
VRF.
Configuring VRF-Aware Services
IP services can be configured on global interfaces, and these services run within the global routing
instance. IP services are enhanced to run on multiple routing instances; they are VRF-aware. Any
configured VRF in the system can be specified for a VRF-aware service.
VRF-Aware services are implemented in platform-independent modules. VRF means multiple routing
instances in Cisco IOS. Each platform has its own limit on the number of VRFs it supports.
VRF-aware services have the following characteristics:
• The user can ping a host in a user-specified VRF.
• ARP entries are learned in separate VRFs. The user can display Address Resolution Protocol (ARP)
entries for specific VRFs.
These services are VRF-Aware:
• ARP
• Ping
• Simple Network Management Protocol (SNMP)
• Hot Standby Router Protocol (HSRP)
• Unicast Reverse Path Forwarding (uRPF)
• Syslog
• Traceroute
• FTP and TFTP
User Interface for ARP
Beginning in privileged EXEC mode, follow these steps to configure VRF-aware services for ARP. For
complete syntax and usage information for the commands, refer to the switch command reference for
this release and the Cisco IOS Switching Services Command Reference, Release 12.2.
Step 9
end Return to privileged EXEC mode.
Step 10
show ip vrf [brief | detail | interfaces]
[vrf-name]
Verify the configuration. Display information about the
configured VRFs.
Step 11
copy running-config startup-config (Optional) Save your entries in the configuration file.
