DES-7200 Configuration Guide Chapter 8 VRF
Configuration
8-10
MCE(config-if-VLAN 60)#ip address 10.10.60.1 255.255.255.0
By now, VRF instances have been created on MCE device.
Create VRF instances on PE device
Step 1: Create VRF instances named VPNa, VPNb and VPNc on PE device
(same names as used on MCE device)
PE(config)#ip vrf vpna
PE(config-vrf)#exit
PE(config)#ip vrf vpnb
PE(config-vrf)#exit
PE(config)#ip vrf vpnc
PE(config-vrf)# exit
Step 2: Create VLAN 40, 50 and 60; join MCE-connecting interface (FastEthernet
0/7) of PE device into VLAN 40, 50 and 60, and associate SVI 40 with VPNa, SVI
50 with VPNb and SVI 60 with VPNc. Steps to create VLANs and join interface
into VLANs are omitted here.
PE (config)#interface vlan 40
PE(config-if-VLAN 40)#ip vrf forwarding vpna
PE(config-if-VLAN 40)#ip address 10.10.40.2 255.255.255.0
PE(config-if-VLAN 40)#exit
PE(config)#interface vlan 50
PE(config-if-VLAN 50)#ip vrf forwarding vpnb
PE(config-if-VLAN 50)#ip address 10.10.50.2 255.255.255.0
PE(config-if-VLAN 50)#exit
PE(config)#interface vlan 60
PE(config-if-VLAN 60)#ip vrf forwarding vpnc
PE(config-if-VLAN 60)#ip address 10.10.60.2 255.255.255.0
By now, VRF instances have been created on PE device.
2) Configure the static route from MCE to VPNa site and PE device
Configure static route on SwitchA (access device of VPNa site)
The address of the interface connecting SwitchA with MCE is 10.10.10.2/24; the
address of interface connecting with VPNa is 192.168.10.1/24. Steps to join
interface into VLAN and configure IP address for interface are omitted here.
# Configure default route on SwitchA, and specify the next-hop for egress packets
as 10.10.10.3.
SwitchA(config)#ip route 0.0.0.0 0.0.0.0 10.10.10.3
Configure static route on MCE device
# Specify static route on MCE; specify the next hop for packets destined to
