User Interface for Traceroute

Beginning in privileged EXEC mode, follow these steps to configure VRF-aware services for traceroute.
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.

User Interface for FTP and TFTP

So that FTP and TFTP are VRF-aware, you must configure some FTP/TFTP CLIs. For example, if you
want to use a VRF table that is attached to an interface, say E1/0, you need to configure the CLI ip [t]ftp
source-interface E1/0 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. That is, 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 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.
Configuring a VPN Routing Session
Routing within the VPN can be configured with any supported routing protocol (RIP, OSPF, EIGRP, or
BGP) or with static routing. The configuration shown here is for OSPF, but the process is the same for
other protocols.
Command Purpose
traceroute vrf vrf-name ipaddress Specify the name of a VPN VRF in which to find the destination
address.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 ip ftp source-interface interface-type
interface-number Specify the source IP address for FTP connections.
Step 3 end Return to privileged EXEC mode.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 ip tftp source-interface interface-type
interface-number Specify the source IP address for TFTP connections.
Step 3 end Return to privileged EXEC mode.
