Keywords: MSR;Routing;Lable
Q: The third across AS of BGP MPLS VPN, why ASBR not passing routing and lable info to PE?
A:
The possible reason is blow:
1) The BGP state of ASBR isn't Established;
2) ASBR are not directly connected;
3) The connected link of ASBR not enable MPLS, Result in lable routing not be choiced by ASBR;
4) ASBR not import the loopback address routing of local AS;
5) The policy of export routing on ASBR config error, result in routing abandon;
6) Maybe there configed ebgp-max-hop between ASBR;
