Hi Eric, - Do you think that it may be useful to have a sentence about Carrier's Carrier IP VPN? I fear that some implementation may allow multiple labels for SAFI 4 (labelled IP) but not for SAFI 128 (VPN) and would not be capable of translating/swapping from N labels on the PE-CE (SAFI 4) side, toward 1 label to the PE-PE (SAFI 128) side. In such case, it may be preferable to advertise this non-capability on the PE-CE side (e.g. by sending the multiple label capability with a max label of 1)
- The current BGP capability encoding does not allow for the sending a different number of accepted labels on a per SAFI basis. I don't know whether this could be useful (in the future) but I do note that, as indicated in the draft, it's already useful to be able to advertise N>1 for some SAFI and N=1 for some others. So may be the flexibility could be useful. I'll leave the cost/benefit choice up to you.
