6.2 Quality of service

i’ve been spending some time on mpls, multicast and qos, the dreaded three… i read a guy on cln who once said multicast is easy… i agree the configuration is not much, but the theory is outrageous…  with mqc qos is more manageable… it’s very similar to mpf on the asa… a basic mpls vpn configuration is comprised of about forty commands… that’s a lot…

the heart and soul of all of this is ccna…
