Issue when configure seamless-MPLS

[Kelvin_k]

Hi,

I found an issue when 7750 interwork with 3rd party device. Anyone can help me? Thanks in advance!

PE1-------BR----------SR7750

BR can establish BGP ipv4 labeled session with PE1 and SR7750.

However SR7750 can't insert PE1's loopback address into route table. When i show bgp route table, i found a error in the output:

key Configuration:

lsp "alu_to_sp2"
to 2.2.2.2
from 5.5.5.5
cspf

exit

Everything seems ok.
