PurposeCommand or Action
Example:
Device(config-if)# ip address
10.7.7.7 255.255.255.255
• • ip-address specifies the IP address of the interface.
• • subnet-mask specifies the subnet mask of the
interface.
Specifies the source of the tunnel interface.
tunnel source {ip-address |type
number}
Step 6
•
ip-address specifies the IP address to use as the
source address for packets in the tunnel.
Example:
Device(config-if)# tunnel source
loop 0
•
type specifies the interface type (for example, serial).
• • number specifies the port, connector, or interface
card number. The numbers are assigned at the factory
at the time of installation or when added to a system,
and can be displayed using the show interfaces
command.
Defines the tunnel destination.tunnel destination
{hostname|ip-address}
Step 7
•
hostname specifies the name of the host destination.
Example:
Device(config-if)# tunnel
destination 10.5.5.5
•
ip-address specifies the IP address of the host
destination.
Associates a VPN routing and forwarding (VRF) instance
with a specific tunnel destination.
tunnel vrfvrf-name
Example:
Device(config-if)# tunnel vrf
finance1
Step 8
•
vrf-name is the name assigned to a VRF.
Configuration Example for GRE Tunnel IP Source and Destination
VRF Membership
In this example, packets received on interface e0 using VRF green are forwarded out of the tunnel through
interface e1 using VRF blue.
ip vrf blue rd 1:1
ip vrf green rd 1:2
interface loop0
ip vrf forwarding blue
ip address 10.7.7.7 255.255.255.255
interface tunnel0
ip vrf forwarding green
ip address 10.3.3.3 255.255.255.0 tunnel source loop 0
tunnel destination 10.5.5.5 tunnel vrf blue
interface ethernet0
