Hello there,

The information as follow is routing table . xe-1/3/2.1 is 10G of submarine cable , and gr-1/1/0.3 is GRE over upstream provider(ISP1).
But I have another GRE over upstream provider(ISP2) , it's interface is gr-2/3/0.2.
My question is how to let gr-2/3/0.2 have higher priority than gr-1/1/0.3 both on protocol LDP & OSPF ?
Althought I set gr-1/1/0.3 as higher metric on OSPF , but the backup path is still gr-1/1/0.3, not gr-2/3/0.2.
Please show us the OSPF LSDB as received from 192.168.145.42:
show ospf database advertising-router 192.168.145.42 extensive | no-more
If 192.168.145.42 does not send You LSA for 192.168.145.2, then ge-2/3/0.2 will not be selected as LFA backup, no matter the metric.

LDP seems have no way to controll.
LDP follows IGP, so if You don't receive OSPF LSA for 192.168.145.2/32 via gr-2/3/0.2, then no amount of LDP configuration can help.
