L2circuit for L2 protocol tunneling

Remember that in the QinQ and L2PT on Junos ELS post we discussed how to configure QinQ and L2PT on EX4600 and how we saw that actually L2PT is not supported on EX4600. Well, in this post we will discuss about a workaround and that is to configure a L2 Circuit(EoMPLS in Cisco world). L2… Keep reading »

Q-in-Q tunneling and VLAN translation allow service providers to create a Layer 2 Ethernet connection between two customer sites. Q-in-Q tunneling is useful when customers have overlapping VLAN IDs because customers’ VLAN (C-VLAN) tags are prepended by… Keep reading »
