MPLS is layer 3 product

其實我更應該講 佢哋概念上係咪相似

mpls就咁prepend一個label
vlan都可以就咁prepend一個vlan id

Provider tag / Customer tag

MPLS mainly will use BGP routing, so that is a Layer 3 service

咩而家玩到咁親大陸人

this is hong kong now what do you mean

唔一樣

vlan 冇 mpls 個 label swap

層數唔可以太多

vlan係12bit係咪

係

另外 vlan 係 global significant

mpls label 係 local significant

所以佢先咁 scalable

MPLS 係 32bit 嘅，其中 20bit 係 label

仲可以有幾層 Label
