MPLS QoS 223
The CEF table shows two equal cost paths taken to reach 222.222.222.3. The local binding
for the prefix is 31, and it distributes to all its LDP neighbors. The remote bindings show
the local label bindings distributed by the LDP adjacent routers. The MPLS router label
switches packets received with a local label with an outgoing label based on the received
remote binding information.
MPLS QoS
QoS is an important component of MPLS. In an MPLS network, QoS information is carried
in the label header’s MPLS CoS field.
Like IP QoS, MPLS QoS is achieved in two main logical steps, as shown in Table 9-2, and
uses the same associated QoS functions. ...
