Re: [mpls-linux-general] How ldp assigns labes

[Marco S. <mar...@s2...>]

You mean a setup like this?

=A0=A0=A0=A0=A0 =A0 ---B---
      /         \
    A<=A0=A0=A0=A0=A0 =A0=A0=A0=A0=A0>D
      \         /
 =A0=A0=A0=A0=A0=A0 ---C---

This scenario doesn't work since you change the link cost (in OSPF) on one
link. The LDP-implementation doesn't support equal cost multipaths (ECMPs).

Routes are redistributed by the zebra routing manager, you may look at the
resources of quagga.net to see how the protocol deamons interact with
each other.
