Configuring VRF-lite for IPv6
Configuring the User Interface for Traceroute
To configure VRF-aware services for traceroute, perform this task:
Configuring the User Interface for FTP and TFTP
You must configure some FTP and TFTP CLIs in order for FTP and TFTP to be VRF-aware. For 
example, if you want to use a VRF table that is attached to an interface (for example, E1/0), you need to 
configure the ip [t]ftp source-interface E1/0 command to inform [t]ftp to use a specific routing table. 
In this example, the VRF table is used to look up the destination IP address. These changes are 
backward-compatible and do not affect existing behavior. You can use the source-interface CLI to send 
packets out a particular interface even if no VRF is configured on that interface.
To specify the source IP address for FTP connections, use the ip ftp source-interface show mode 
command. To use the address of the interface where the connection is made, use the no form of this 
command.
To configure the user interface for FTP and TFTP, perform this task:
To specify the IP address of an interface as the source address for TFTP connections, use the 
ip tftp source-interface show mode command. To return to the default, use the no form of this 
command.
Step 4
Switch(config-if)# ip vrf forwarding 
vrf-name
Configures VRF on the interface.
Step 5
Switch(config-if-vrf)# ip address 
ip-address subnet-mask
Enters the IP address for the interface.
Step 6
Switch(config-if-vrf)# ip verify 
unicast source reachable-via 
rx allow-default
Enables uRPF on the interface.
Step 7
Switch(config-if-vrf)# end
Returns to privileged EXEC mode.
Command Purpose
Command Purpose
traceroute vrf vrf-name ipaddress
Specifies the name of a VPN VRF in which to find the destination 
address.
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# ip ftp 
source-interface interface-type 
interface-number
Specifies the source IP address for FTP connections.
Step 3
Switch(config)# end
Returns to privileged EXEC mode.
