[Tsvwg] Comments on draft-davie-tsvwg-rsvp-l3vpn-02

Hi Bruce, Francois, and Ashok,

 

I have a few comments on your draft:

 

1)      Section 3.2, "The router...............determines the local VRF
context by finding a matching VPN-IPv4 prefix with the specified RD that
has been advertised by this router into BGP" 

- Can you clarify how the local VRF context is determined? Can the VRF
context be determined directly from the RD or does the router search
through advertised routes as described in the above sentence? 

2)      Section 3.3, "The Resv message is sent to the IP address
contained within the RSVP_HOP object in the Path message." 

- I believe you mean the RSVP_HOP object in the Path state (not
message). Note that you can actually delete this sentence (it is a
repeat).

3)      Section 5.2.2, paragraph starting with "When the upstream RSVP
hop sends a Path message....." 

a.       It is worth clarifying that just as there are upstream and
downstream RSVP hops, there are upstream and downstream ASBRs in the
description of how the Path messages are processed. 

b.       The first Path message is processed by the ASBRs thus creating
Path state; Resv messages and all subsequent Path messages are only
processed by the upstream and downstream RSVP hops, causing eventually
the ASBR Path state to expire. It may help to clearly state this in the
paragraph. Also, are there any issues with this, i.e. the processing of
the first Path message of all end-to-end reservations at the ASBRs?

 

Regards,

Ferit
