[mpls-linux-general] [mpls example]another question

[allen <as...@gm...>]

Hi All,

 I want to continue trying another example as follows. Similarly to =
establish two way LSP(from HostA to HostB using label 1000, and HostB to =
HostA using label 1002). then use "ping" to test(from HostA to HostB). =
But failed again. Please tell me the problem of configuration and how to =
modify. thanks
