Configlets
Comments • The N-PE is a 7600 with an OSM or SIP-600 module. Provisioning is the same as the ERS (EVPL)
example.
• The U-PE is a generic Metro Ethernet (ME) switch.
• PACL with one user-defined entry.
• BPDUs (CDP, STP and VTP) are tunneled through the MPLS core.
• Storm control is enabled for unicast, multicast, and broadcast.
