Hi all, i know this is not the right section but kindly pardon me since i have recieved most of the answers to my confusion from this section. i have a very simple question regarding mpls. I am confused regarding 2 outgoing tags shown in show mpls forwarding
When either of this is used ? i know in case of PHP we will expect to see POP tag right ? but when shall i see UNTAGGED ? in my view a router will see untagged when it doesnt recieve the label from the advertising router am i right ? so when will a router will NOT assign labels to prefixes ?
