Topology
Pic.3 - MPLS Topology 3
Task 1
Based on the previous lab configuration, assume there is no MPLS between PE1 and PE2 (already removed in Lab 184). Remove L2TPv3 configuration from PE1 and PE2.
Task 2
Configure PE1 and PE2 to provide layer 2 VPN service between CE3 and CE4. If the task requires this, you can create required static routes and additional interfaces. Use AToM encapsulation to accomplish the task.
Solution
Yet another "interesting" hack here. Don't you miss the time when things were simpler and there was only one way of getting it done?
Task 1
Based on the previous lab configuration, assume there is no MPLS between PE1 and PE2 (already removed in Lab 184). Remove L2TPv3 configuration from PE1 and PE2.
CE1 (R1) Config:
!
no pseudowire-class VPN1
!
int f0/1.15
no xconnect 10.0.3.3 45 encapsulation l2tpv3 pw-class VPN1
!
CE2 (R3) Config:
!no pseudowire-class VPN1
!
int f0/0.34
no xconnect 10.0.1.1 45 encapsulation l2tpv3 pw-class VPN1
!
Task 2
Configure PE1 and PE2 to provide layer 2 VPN service between CE3 and CE4. If the task requires this, you can create required static routes and additional interfaces. Use AToM encapsulation to accomplish the task.
CE1 (R1) Config:
!interface Loopback1
ip address 1.1.1.1 255.255.255.255
!
mpls ldp router-id Loopback1 force
!
interface Tunnel13
ip address 10.13.13.1 255.255.255.0
mpls ip
tunnel source Loopback0
tunnel destination 10.0.3.3
!
ip route 3.3.3.3 255.255.255.255 Tunnel13
!
interface FastEthernet0/1.15
encapsulation dot1Q 45
xconnect 3.3.3.3 45 encapsulation mpls
!
CE2 (R3) Config:
!interface Loopback1
ip address 3.3.3.3 255.255.255.255
!
mpls ldp router-id Loopback1 force
!
interface Tunnel13
ip address 10.13.13.3 255.255.255.0
mpls ip
tunnel source Loopback0
tunnel destination 10.0.1.1
!
ip route 1.1.1.1 255.255.255.255 Tunnel13
!
interface FastEthernet0/0.34
encapsulation dot1Q 45
xconnect 1.1.1.1 45 encapsulation mpls
!
Note!
In previous lab we have removed LDP protocol. For this solution to work, LDP must be implemented (it is used on Tunnel interfaces).
