    Hi everybody!

 

 

    Do you know where can I find information on MPLS hardware vendors, models and it's features?

 

 

    I alse have a doubt regarding LDP Session Initialization as described in draft-ietf-mpls-ldp-06, section 2.5.3, pages 15/16.

 

    2 LSRs are initiating an LDP session, LSR2 is active.

 

                    LSR1---------------------------------------LSR2

 

    LSR2 establishes the TCP connection and sends an initialization message to LSR1.

    LSR1 processes the message and finds the proposed session parameters to be acceptable. It sends an Initialization message proposing it's own session parameters and a KeepAlive message to signal acceptance of LSR2's parameters.

    Next, LSR2 processes LSR1's init message - here's where the doubts begin.

 

    First, lets suppose the parameters LSR1 wishes to use are unacceptable to LSR2. What happens?

        According to the LDP spec, LSR2 closes the connection [Page 16, 2.b)] - remember that LSR1 agreed on LSR2's parameters.

 

    Second, suppose that the parameters LSR1 wishes to use are acceptable to LSR2.

        LSR2 replies with a KeepAlive message - and I presume that the parameters used are proposed by LSR1.

 

 

 

    Am I missing anything?

 

 

    Thanks for your help,
