Hi Csaba,
We understand SR-MPLS is a more mature standard than SRv6, and this is
reflected in current protocol implementations. Considering the Tofino data
plane in the latest freeRtr release, could you please clarify the differences
between the SRv6 support and the SR-MPLS support?
This is important for us to define if it is viable to include SRv6 in the
SC22 demo or limit to SR-MPLS only. For SR-MPLS, we understood that we only
support 1 label insertion, while in PolKA we can define explicit paths.
Thank you,
Cristina
