Hi Acee, Fate sharing of same SRGB space by multiple protocols may not be a good idea. IMHO, SRGB configuration should be @ protocols and per instance.
Also you would agree, this has no relevance for the ability to configure any range by the operator to keep the same SRGB in multi-vendor deployments. -- Uma C. From: spring [mailto:[email protected]] On Behalf Of Acee Lindem (acee) Sent: Thursday, July 23, 2015 5:49 AM To: [email protected]; [email protected] Subject: Re: [spring] Modeling SRGB configuration for draft-ietf-spring-sr-yang I strongly prefer option 1. The purpose of the SRGB range is to allow devices in the segment routing domain to use different MPLS label ranges for segment routing. This is necessary either due to the devices having allocated MPLS label ranges for other purposes (e.g., LDP or static LSPs) or the devices not supporting the full MPLS label range. SRGB is not meant to be used to allocate unique label ranges to various protocols or purposes.

We had some comment in Dallas on difficulties that having common label range shared between protocols could lead to. During discussion in our design team, some point was also raised on routing protocol migrations that may be safer using a per protocol SRGB (so configuration the SRGB at IGP level rather than globally). We would like to hear from the WG about the preference and arguments for both approaches : Approach 1) keep SRGB configuration at top level, and so routing protocols will share the same label space (today proposal) Approach 2) move SRGB configuration to protocols, each routing protocol manages its own label space. Thanks to provide your feedback in order to solve this issue and have a consensus.
