Re: [mpls] 答复: MPLS WG last call on draft-ietf-mpls-in-udp-03.txt

[Xuxiaohu <[e-mail]>]

Hi Sri,

It’s no problem provided that anybody was willing to use VXLAN-GPE to replace the existing MPLS-based applications such as L2 or L3 VPN services. Furthermore, there is another choice for VXLAN extension other than VXLAN-GPE, which has been described in http://tools.ietf.org/html/draft-yong-l3vpn-nvgre-vxlan-encap-00. I’m willing to hear your further comments on the comparison of these two options for VXLAN extension (Maybe MPLS WG is not a suitable place to talk about this topic).

Xiaohu

Hi Xu,

The existing encapsulations you pointed out were defined a long time ago. Whereas the other two are just being proposed now. Moreover if we follow this approach it will require standardizing UDP port numbers for each new protocol to encap into UDP.

There is no reference cited for the "MPLS-in-IP" encapsulation.

[Xiaohu] MPLS-in-IP and MPLS-in-GRE are actually specified in the same RFC that is RFC4023.

What is the applicability of this encapsulation compared to the generalized mechanism in draft-quinn-vxlan-gpe ?

[Xiaohu] The applicability of this encapsulation is the same as the existing IP-based encapsulations for MPLS (e.g., MPLS-in-GRE).

Best regards,
Xiaohu
