Lab 183 - AToM Vlan Mode

Prerequisites: CCNP level skills.

Topology

Pic3. MPLS Topology 3

If you don't want to waste your time on configuring the above diagram, you can use my configuration available here (in this case task 1 and task 2 are already complete).

Task 1
Remove direct connection (backdoor) between CE3 (R5) and CE4 (R4) by deleting sub-interfaces Fa0/0.45. You can also remove previous lab configuration (lab 182). Create configuration that matches Pic. 3 (above)

Task 2
Remove MP-BGP from both PE routers (we create overlay VPNs this time).

Task 3
Advertise 192.168.5.x and 192.168.4.x subnets into EIGRP. After you have completed task 4, these subnets should be reachable (you can remove network 172.16.0.0 from those routers).

Task 4
Configure Any Transport over MPLS between CE3 (R5) and CE4 (R4). Use IP address 10.45.45.x, where 'x' is the router number. Interfaces should belong to Vlan 45. Pseudowire configuration in PE routers should use number 45.

SOLUTION

Task 3
Advertise 192.168.5.x and 192.168.4.x subnets into EIGRP. After you have completed task 4, these subnets should be reachable (you can remove network 172.16.0.0 from those routers).

CE3 (R5) Config:
!
router eigrp 100
 no network 172.16.0.0
 network 192.168.5.0
 network 10.0.0.0
 no auto-summary
!

CE4 (R4) Config:
!
router eigrp 100
 no network 172.16.0.0
 network 192.168.4.0
 network 10.0.0.0
 no auto-summary
!

Task 4
Configure Any Transport over MPLS between CE3 (R5) and CE4 (R4). Use IP address 10.45.45.x, where 'x' is the router number. Interfaces should belong to Vlan 45. Pseudowire configuration in PE routers should use number 45.

PE1 (R1) Config:
!
interface FastEthernet0/1.15
 encapsulation dot1Q 45
 xconnect 10.0.3.3 45 encapsulation mpls
!

PE2 (R3) Config:
!
interface FastEthernet0/0.34
 encapsulation dot1Q 45
 xconnect 10.0.1.1 45 encapsulation mpls
!

Verification:

PE1 (R1):


PE2 (R3):



CE4 (R4):
