Configuring VRF-Aware VPDN Tunnels
The vpn command enables the VRF-Aware VPDN Tunnels feature by associating an IP address
configured in a VPDN group with a VRF. This is applied to a VPDN group as shown in the following
Summary Steps.
Use the following commands to configure VRF-aware VPDN tunnels on the router:
SUMMARY STEPS
1. enable
2. configure terminal
3. vpdn-group name
4. request-dialin
5. protocol [l2f | l2tp| pptp]
6. domain domain-name
7. exit
8. vpn {vrf vrf-name | id vpn-id}
9. source-ip ip-address
10. initiate-to ip ip-address [limit limit-number] [priority priority-number]

Note For Cisco IOS Release 12.2(31)SB5 and later releases, when configuring VRF-aware VPDN tunnels on
the Cisco 10000 series router, different tunnels can have overlapping IP addresses across VRF instances.
