Title: 邮件

Thanks a lot.

 

I have another question. In section 6.4, it states as following :

 

   6.4 Signaling for Facility Protection
  
      A PLR may use one or more bypass tunnels to protect against the
      failure of a link and/or a node.  These bypass tunnels may be
      setup in advance or may be dynamically created as new protected
      LSPs are signaled.

 

My question is how to create the bypass tunnels dynamically?

how do the LSRs in the protected path know to be PLR and to create bypass tunnel with what attributes like destionation etc.
