5. Create or add a route target to the import and export lists of VPN extended
communities for this VPLS instance.
host1(config)#bridge customer1 vpls route-target both 100:1
The PE router uses the lists of VPN extended communities to determine which
routes are imported by this VPLS instance.
BEST PRACTICE: We recommend that you add the route target to both the VPLS
instance's import list and export list of VPN extended communities. To do so, use
the both keyword.
Multiple VPLS instances that use the same transport virtual router cannot have the
same route distinguisher. Conversely, multiple VPLS instances that use different
transport virtual routers can have the same route distinguisher.
For example, the following commands configure the transport virtual router for each
of three VPLS instances: vplsA, vplsB, and vplsC. The transport virtual router for both
vplsA and vplsC is vr1, and the transport virtual router for vplsB is vr2.
host1(config)#bridge vplsA vpls transport-virtual-router vr1
host1(config)#bridge vplsB vpls transport-virtual-router vr2
host1(config)#bridge vplsC vpls transport-virtual-router vr1
Because vplsA and vplsC use the same transport virtual router, vr1, you cannot assign
them the same route distinguisher. Consequently, the following operation fails, and
the router displays an error message.
host1(config)#bridge vplsA vpls rd 1.1.1.1:10
host1(config)#bridge vplsC vpls rd 1.1.1.1:10
% Unable to set VPLS route distinguisher (can't re-use the route-distinguisher)
However, both vplsA and vplsB can use the same route distinguisher because their
transport virtual routers are different. Consequently, the following commands are
valid.
host1(config)#bridge vplsA vpls rd 1.1.1.1:10
host1(config)#bridge vplsB vpls rd 1.1.1.1:10
