How to forward a vrf to multiple MPLS-TE tunnels

Hi

I am using a Cisco ISR4331 as a PE MPLS router and wish to forward a vrf named TEST over multiple MPLS-TE tunnels.

The 2 x MPLS-TE tunnels each go to different PE MPLS routers.

Both MPLS TE tunnels are up and operational.

Under ip vrf TEST I have used the command "bgp next-hop loopback 0"

I am assuming that the "loopback 0" in the above command is the far-end iBGP loopback address ?

Will this command ensure that the vrf will utilise both tunnel 1 and tunnel 2 ?

 

Below is an extract:-

 

ip vrf TEST
 description VRF_TEST
 rd 24316:6100
 route-target export 24316:6001
 route-target import 24316:6001

 bgp next-hop loopback 0

!

!

interface Tunnel1
 ip unnumbered Loopback0
 mpls ip
 mpls label protocol ldp
 mpls traffic-eng tunnels
 tunnel mode mpls traffic-eng
 tunnel destination 10.1.2.3
 tunnel mpls traffic-eng autoroute announce
 tunnel mpls traffic-eng forwarding-adjacency
 tunnel mpls traffic-eng priority 7 7
 tunnel mpls traffic-eng load-share 1
 tunnel mpls traffic-eng path-option 1 dynamic
 tunnel mpls traffic-eng record-route
 tunnel mpls traffic-eng fast-reroute bw-protect node-protect
!
interface Tunnel2
 ip unnumbered Loopback0
 mpls ip
 mpls label protocol ldp
 mpls traffic-eng tunnels
 tunnel mode mpls traffic-eng
 tunnel destination 10.1.2.4
 tunnel mpls traffic-eng autoroute announce
 tunnel mpls traffic-eng forwarding-adjacency
 tunnel mpls traffic-eng priority 7 7
 tunnel mpls traffic-eng load-share 1
 tunnel mpls traffic-eng path-option 1 dynamic
 tunnel mpls traffic-eng record-route
!

 

Regards

 

Mick

Re: How to forward a vrf to multiple MPLS-TE tunnels

Hi

 

Just to let you know, I found the solution.

After reading some literature from the Cisco web site, I found that the vrf TEST was actually traversing the 2 x MPLS-TE tunnels.

The following commands helped me see this:-

#show ip cef cef TEST

#show ip cef  cef TEST 10.69.3.251         (10.69.3.251 being a remote network of vrf TEST)

#show mpls traffic-eng tunnels tunnel 1

#show mpls traffic-eng tunnels tunnel 2

 

I also removed the command "bgp next-hop loopback 0 " from the vrf TEST.

 

Regards

 

Mick
