Title: RE: Doubt in draft-ietf-mpls-te-mib-07.txt

Hello All,

            What are the steps to be considered when mapping the DSCP field in the ipv4/ipv6

            to FEC's at ingress.

            What changes are necessary for the distribution protocol.

            I dont need the routers to examine the dscp field along each hop.

            Thanks in advance,

            Regards,

            Abhay

Ashwin,

           Sometime ago the CR-LDP sentence in the MIB was not present for resource allocation.

           And during those times,I used my own MIB variables,just to have a little fun and give CR-LDP

           a fair chance.Now u see it,later u wont...again..any extensions to CR-LDP,you will see it again.

           In good humour.

           Regards,

           Abhay

Subject: Why do we need CR-LDP Tunnel Resource Table in TE MIB 7?

 

Hello All

 

 Why the CR-LDP Tunnel Resource Table is added in the draft-ietf-mpls-te-mib-07.txt.

 There is also a mplsTunnelResourceTable which has all the parameters

 of the mplsTunnelCRLDPResTable.

 

 And the note specifically says that this is in addition to the Tunnel Resource Table .

 

The mplsTunnelCRLDPResTable allows a manager to
          specify which CR-LDP-specific resources are desired
          for an MPLS tunnel if that tunnel is signaled using
          CR-LDP. Note that these attributes are in addition
          to those specified in mplsTunnelResourceTable. This
          table also allows several tunnels to point to a
          single entry in this table, implying that these
          tunnels should share resources.

 

And the parameters of the table are same expect the mplsTunnelCRLDPResFlags.

Can you please tell me what is the differance between these 2 tables and why is this

needed ?

 

 

Ashwin
