BGP on VRF - Unable to allocate label: 'MPLS_LSD' detected

Hi 

 

We created 2 Full BGP , each of different VRF, and following warning out.   We had alredy set :

 

mpls label range table 0 16000 1048575

 

But 2 Full BGP for internet routing  may not sufficient  for 1Mil route.  We using typhoon card . 

 

: bgp[1067]: %ROUTING-BGP-3-ERR_ALM_ONE_LABEL : [7] : Unable to allocate label: 'MPLS_LSD' detected the 'resource not available' condition 'Code(0)': No space left on device

I guess MPLS is not necessary here,  why default is tagging the route to MPLS ?  How can we avoid this.

Hello,

 

You may want to switch to per-vrf label assingment. Otherwise MPLS will try to assign local label per each prefix and you hit limitation. Please find details here:

Niko suggestion works. Just need to change to IOX-XR config, mpls labeling in  router BGP, VRF and ipv4 unicast.
