Router os is v3.22 standard mpls package is installed. ( not mpls-test)
when i add vlan interface in /mpls ldp interface router goes up to 100% for 5 minutes then back to 5 %
After that all http traffic got worse , but icmp ( ping and trace ) show that is all ok on the network.
I started turning off mpls until i come to network where i have vlans and when i disable mpls there all worked as before.
mikrotik team?
