Chapter 39 Configuring VRF-lite
Configuring VRF-Aware Services
VRF-aware services are implemented in platform-independent modules. VRF provides 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)
• Unicast Reverse Path Forwarding (uRPF)
• Syslog
• Traceroute
• FTP and TFTP
• Telnet and SSH
• NTP
