Re: [Idr] I-D Action: draft-ietf-idr-bgpls-inter-as-topology-ext-01.txt

Dear authors of draft-ietf-idr-bgpls-inter-as-topology-ext-01,

Can you clarify why extensions already defined in
https://tools.ietf.org/html/draft-ietf-idr-bgpls-segment-routing-epe-17 are
not sufficient to cover your use case ?

As a side observation normally peering links are enabled in the IGP as
passive - not "redistributed as static routes".

Thx,
R.
