Hi Peng,

I am not sure if you got a response on your email below.

I believe the authors of the draft-ietf-pce-segment-routing are planning to 
address the gap for the Segment Type 7 as specified in 
https://tools.ietf.org/html/draft-ietf-spring-segment-routing-policy-02#section-4
 which should address the gap you’ve highlighted below.

The Segment Type 5 defined in 
https://tools.ietf.org/html/draft-ietf-spring-segment-routing-policy-02#section-4
 which is also specified for BGP in 
https://tools.ietf.org/html/draft-ietf-idr-segment-routing-te-policy-05#section-2.4.3.2.5
 covers the IPv4 unnumbered links. Please note that IPv4 unnumbered is 
applicable for p2p links and while some protocol encodings also allow for 
specification of the remote endpoint address and ID, that is optional. The 
local address and ID is sufficient to identify the link/adjacency.

Hope that clarifies.

Thanks,
Ketan

Subject: [spring] IP unnumbered SR-adjacency encoding issue in PCEP-SR & IDR-SR




Dear authors,

I found that draft-ietf-pce-segment-routing-14 only defined SR-ERO (NT=5) for 
IPv4 unnumbered adjacency, IPv6 absent.

On the contrary, draft-ietf-idr-segment-routing-te-policy-05 only defined 
Segment (type=7 or 10) for IPv6 unnumbered adjacency, IPv4 absent. In this 
document Segment (type=5) looks like only for P2P adjacency.

Could you give a more clarification?



Thanks

Deccan
