Jun,
Thank you very much for the answers.  Yes, the questions are to draft-hujun-idr-bgp-ipsec-01.

Here are more questions:

  *   If I want to find the least set of information for a node to propagate for IPsec tunnels to a set of nodes, can I use "Next Hop" field in the MP-NLRI for the Local Tunnel Endpoint? So the Tunnel-Encap Path Attribute doesn't have to include the "Local Tunnel Endpoint Address" subTLV
  *   What is the difference between "Private Routing Instance" and "Child SA Traffic" selection? Can they be the same?
  *   Can the "Private Routing Instance" be listed as Routes in the MP-NLRI  Path Attribute?
  *   Under what circumstance that you will need "Public routing instance"?   especially, for a network with set of CPEs in one customer AS running as Overlay and the routing instance is locally significant to the Customer domain.

Thank you.

Linda

Subject: RE: [Idr] Questions to draft-hujun-idr-bgp-ipsec-transport-mode-00.txt

Hi Linda,
I assume your questions are really about draft-hujun-idr-bgp-ipsec-01? since draft-hujun-idr-bgp-ipsec-transport-mode-00 doesn't have figure 4;
"Figure 4: does R1 use Subnet A in NLRI? And have Tunnel-Encap with more detailed description on SubnetA<->SubnetB  & SubnetA<->Subnet C? "
 Yes, R1 will advertise subnet-A in NLRI; not sure I understand your 2nd part of the question, but section 2.1 of draft-hujun-idr-bgp-ipsec-01 defines local/remote prefix sub-TLV (NLRI could be used for local prefix)

"How does R1 need to know that Subnet A and Subnet B needs to communicate ahead of time? "
This depends on use case, in this example, both R1 and R2 belong to same admin domain, so this kind of thing could be planned ahead; in other use case, if the remote prefix is not known or user want same Ipsec config for all remote prefix, then an all-zero prefix could be used in remote prefix sub-TLV


"In addition, if the network has 4 routers, R1, R2, R3 and R4. Does the Update from R1 include all the <Local- Remote> pairs in each single UPDATE?

i.e. when R1 sends out the UPDATE for the Subnet A attached to R1, the UPDATE from R1 has to include
        Local subnet A <-> remote subnet B on R2
Local subnet A <-> remote subnet D on R3
Local subnet A <-> remote subnet F on R4


Is it correct? If there are 100 nodes in the network, the UPDATE message has to include 100 pairs?
"
As explained above, it could be done this way, but not necessary; it really depends on granularity user case needs

Jun,

I have some questions on your draft:

Figure 4: does R1 use Subnet A in NLRI? And have Tunnel-Encap with more detailed description on SubnetA<->SubnetB  & SubnetA<->Subnet C?

How does R1 need to know that Subnet A and Subnet B needs to communicate ahead of time?

Hi,
Here is a new draft for using BGP to provision IPsec transport mode protected tunnel config; this draft is in companion with draft-hujun-idr-bgp-ipsec-01 (Ipsec tunnel mode) to provide a complete solution of using BGP provision IPsec config.

Review and comment will be appreciated.

Abstract:
   This document defines a method of using BGP to advertise IPsec
   transport mode protected tunnel (like GRE tunnel with IPsec transport
   mode protection) configuration along with NLRI, based on
