[j-nsp] ERX Problem : MP BGP route import not working between 2 PE

[Guillet, David (David)]

Hi,
	Finally I managed to make it work, I simply announce the Tunnel
interface into BGP and it works :

interface tunnel mpls:r1-to-r2
 ip unnumbered loopback 0
 tunnel mpls label-dist rsvp
 tunnel destination b.b.b.b
 tunnel mpls autoroute announce ospf
 tunnel mpls autoroute announce bgp <<<<<-------------- 
 tunnel mpls autoroute metric absolute 42
 exit
