esr(config)# object-group network ADV_LABELS
esr(config-object-group-network)# ip prefix 10.10.0.1/32
esr(config-object-group-network)# ip prefix 10.10.0.2/32
Apply the created object-group on both routers:
esr(config)# mpls
esr(config-ldp)# ldp
esr(config-ldp)# advertise-labels ADV_LABELS
Check:
On ESR_B make sure that the tag is assigned to the appropriate prefixes:
esr# sh mpls ldp bindings 10.10.0.1/32
10.10.0.1/32
local label: exp-null
remote label: 75 lsr: 172.16.0.1
And not assigned to 192.168.2.0/24
esr# sh mpls ldp bindings 192.168.2.0/24

12.5 L2VPN Martini mode configuration
L2VPN allows you to organize ethernet frames transmission through the MPLS domain. Allocation and
distribution of tunnel labels, in this mode, is carried out by means of the LDP. In the implementation of L2VPN
can be divided into two cases:
P2P — "point-to-point" tunnel
VPLS — "point-to-multipoint" tunnel
In both cases, a virtual channel (pseudo-wire) is created to transmit ethernet frames between routers. To
negotiate pseudo-wire parameters, as well as to allocate and transfer tunnel labels between routers, an LDP
session is established in the targeted mode.
