MPLS中的标签分发协议(LDP)
最近,我一直在研究MPLS技术。在阅读了MPLS的一些功能后,我心中对此有疑问。 A---B---c | | D----E 假设路由器A,E是LER,而路由器B,C,D是LSR,我们要从A-> E发送流量。我了解到,只有LSR可以初始分配标签,而在LDP中,下游路由器会启动标签的分发以及标签/ FEC绑定。 Can someone please explain me 1.)how A(LER) can transmit the packets to B(LSR). 2.)how can B know which label and port to forward,if it receives the distribution from C(Where C and D are downstream routers) 谢谢。
