Configuring Vrf Interfaces On Pe Routers For Each Vpn Customer - Cisco CRS Configuration Manual

Connecting MPLS VPN Customers

Configuring VRF Interfaces on PE Routers for Each VPN Customer

Perform this task to associate a VPN routing and forwarding (VRF) instance with an interface or a subinterface
on the PE routers.
Note You must remove IPv4/IPv6 addresses from an interface prior to assigning, removing, or changing an
interface's VRF. If this is not done in advance, any attempt to change the VRF on an IP interface is rejected.
SUMMARY STEPS
1. configure
2. interface type interface-path-id
3. vrf vrf-name
4. ipv4 address ipv4-address mask
5. Use the commit or end command.
DETAILED STEPS
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters Global Configuration mode.
Step 2 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config)# interface TenGigE 0/3/0/0
Enters interface configuration mode.
Step 3 vrf vrf-name
Example:
RP/0/RP0/CPU0:router(config-if)# vrf vrf_A
Configures a VRF instance and enters VRF configuration mode.
Step 4
ipv4 address ipv4-address mask
Example:
RP/0/RP0/CPU0:router(config-if)# ipv4 address 192.168.1.27 255.255.255.0
Configures a primary IPv4 address for the specified interface.
Step 5 Use the commit or end command.
