Hi Martin, For the matched LFIB entry with unlabeled outgoing forwarding information, I agree your opinion that public traffic need to be forwarded. I think the above LFIB entry can easiely drop VPN traffic according to no bottom flag of incomming LDP/SR label. Regards, PSF

Martin, > it follows an IGP default route to a central device, So putting aside that such default must point domian wide to the same address (could be anycast if you are careful) once this "central device" receives a packet and does a BGP full table lookup it will again try to encapsulate it in

2020-08-27 Thread Martin Horneffer
Hello everyone, may I come back the the question below? Or rather let me update it a little: In case an SR-MPLS path is broken, should a node rather drop the packet, or forward it? This can happen whenever the IGP points to a certain next hop, but that neither supplies a valid SID, nor allows

Hi, I fully agree with Ketan. For (a), it is obvious that if the next-hop and locator belong to the same prefix, we minimize the prefixes to be advertised, hence we’ll have smaller route tables. But it is up to the user to decide that. The spec should support both. Similar for (b). There may
