destined for the 124.2.0.0/16 subnet. The following is the configuration for R3:
rsvp add interface to_RS3
rsvp start
! Configures VLANs and interfaces
vlan make trunk-port gi.15.1
customer ports must be trunk ports for 802.1q packets
vlan create ldp_if1 id 120
vlan create ip_ldp port-based id 175
vlan add ports gi.12.2 to ip_ldp
vlan add ports gi.12.1 to ldp_if1
interface create ip to_rs2 address-netmask 210.1.1.2/16 vlan ip_ldp
interface create ip to_rs4 address-netmask 110.1.1.1/16 vlan ldp_if1
interface add ip lo0 address-netmask 111.1.1.3/32
! Configure OSPF
