In this VRF-lite implementation, other Layer 4+ services and applications are not supported on a per-VRF basis - such as Telnet server, SSH server, file copy, system log, SNMP server, DHCP server, DHCP relay, NTP server, etc. However, these services will remain supported in the global VRF domain context, which is same as in a non-VRF environment.
