Hi Robert, Good question. In short you may need some mechanism in the forwarding plane to isolate the traffic in the default topology from the traffic in other topologies. Some of the candidate technologies are described in draft-ietf-teas-enhanced-vpn. Best regards, Jie From: Robert Raszuk

Hi Tony, Thank you for sharing your opinion. I found there are so many discussion later, so I think in fact our opinion are consistent. : ) What I wanted to say before is that L2-member can not configure MT-ID, not say L2-bundle (it is a L3 interface) itself. According to Les

Hi, Out of pure curiosity here - how are you going to stop any other traffic (SR or non SR) to take as much as it likes of any link being part of the default topology ? Thx, R. ___ Lsr mailing list Lsr@ietf.org https://www.ietf.org/mailman/listinfo/lsr

Hi Tony, Thanks for your comments. My current understanding is TLV 25 could reference the associated L3 link advertised in either TLV 22 or 222. With your proposal of keeping things orthogonal, does it mean that TLV 25 would only be used to advertise the member link attributes of the

Hi Yali, I think the overall concept of ifit is interesting enough. My concern is that we aren't adding things to routing protocols (in particular IGPs) simply to allow for another way of configuring applications in the network. This is what netconf/YANG etc, are for. If I were trying to code

Jie - The format of the TE-attribute sub-TLVs is defined and does not change based upon the TLV in which it is advertised. So I do not see that any additional specification is required. In rereading draft-dong-lsr-sr-enhanced-vpn, I am wondering what is the scope you desire for link
