Diiferent LSPs for different customer

[Mukesh_Devangan]

I have two customers in VRF1 and VRF2.I want the traffic from them to pass through different LSPs ,which are having different bandwidth allocations.

Can anyone help me in how can I achieve this.

Hi Mukesh,

This can be achieved using a trick in the MPLS for associating the routes attached to a VRF to a particular next hop.

Router(config)# ip vrf RED
Router(config-vrf)# rd 400:1
Router(config-vrf)# route-target import 400:2
Router(config-vrf)# route-target export 400:2
Router(config-vrf)# bgp next-hop loopback 10 

Using this the routes will see the tail end routers loopbck IP as the next Hop.

Now in case of MPLS tunnels you may have to enable targetted LDP,between the two PEs,this will help in assigning label to the next hop PE's loopback address.You can enable tldp by using mpls ip in tunnel interface.

interface Tunnel100
 description *** TE Tunnel to PE2 ***
 ip unnumbered Loopback0
 mpls ip
 tunnel destination 10.10.10.2
 tunnel mode mpls traffic-eng
 tunnel mpls traffic-eng path-option 1 explicit name VRF_TEST_TRAFFIC_to_PE_2
 tunnel mpls traffic-eng path-option 2 dynamic
 tunnel mpls traffic-eng record-route

Similar configuration should be done on the remote PE2 for next hop as PE1.

Hope it helps!
