Hi Arkadiy,

I checked the latest <draft-ietf-ospf-segment-routing-extensions-24> and <draft-ietf-isis-segment-routing-extensions-15> for reference and comparing, and they both use a 8 bits Algorithm.
One of the description: "Algorithm: Single octet identifying the algorithm."

Interesting to use more than 8 bits for BIER's future flexibility :-)

Hello Working Group,
After initial discussions between multiple participants of the working group, we consolidated that BIER's future flexibility would be well served if we extend the IGP signaling BAR field to 16 bits. We are currently reviewing various use-cases that can greatly benefit from this enhancement.
I would appreciate if the proposed change could be considered as part of IETF Last Call review.
