[j-nsp] VPLS Multihoming

Hi Guys,

I've configured two MX routers (PE) to use VPLS multihoming.
Both PE routers connect into two EX4500's in VC mode
PE1 is configured as primary and PE2 is configured as backup

The config on each MX is:

PE1:
PE1> show configuration routing-instances
VPLS-DirectNetworks {
    instance-type vpls;
    vlan-id all;
    interface ge-1/1/0.1;
    route-distinguisher 10.255.0.11:2;
    vrf-target target:65100:2;
    protocols {
        vpls {
            site-range 20;
            no-tunnel-services;
            site IC2-VPLS {
                site-identifier 2;
                multi-homing;
                site-preference primary;

PE2:
PE2>show configuration routing-instances
VPLS-DirectNetworks {
    instance-type vpls;
    vlan-id all;
    interface ge-1/1/0.1;
    route-distinguisher 10.255.0.12:2;
    vrf-target target:65100:2;
    protocols {
        vpls {
            site-range 20;
            no-tunnel-services;
            site IC2-VPLS {
                site-identifier 2;
                multi-homing;
                site-preference backup;

My question is - on PE2 is it normal for it to show the  VPLS connections in a 'LN' (local site not designated) state, as shown below:

PE2>show vpls connections
Layer-2 VPN connections:

<snip>

Legend for interface status
Up -- operational
Dn -- down

Instance: VPLS-DirectNetworks
  Local site: IC2-VPLS (2)
    connection-site           Type  St     Time last up          # Up trans
    1                         rmt   LN
    2                         rmt   LN

This page on the juniper site seems to show a similar output but I just wanted to confirm
