Hi,
For each remote-peer (to provide VLL or VPLS) will PE 01 import all remote labels?
======Yes, the HUB router will import the all the remote peer labels to establish the P2MP network topology.

What commands can be used to check LIB and LFIB routes?
======As ster said, command "display mpls lsp" displays the LFIB information. Also, you can get more information using command "display mpls ldp lsp".

What is a safe/sugested number of labels in LIB/LFIB to keep the MPLS cloud stable?
======As far as I know, there is no such rule to meet your requirement, and in my opinion, I don't think that MPLS label value could inflence the network.

Do a LDP full mesh from all PE to all PE decrease performance in the MPLS cloud?
======Yes, the LDP session will require the device assigning physical performance to keep it alive, and absolutely, it will decrease router performance.

Hello，

1. A remote LDP session is used to allocate inner L2VPN labels.If a Martini VLL or VPLS connection is to be established between two LSRs, the remote LDP session must be established between the LSRs to allocate inner labels.

2. The display mpls lsp command displays LSP information.

3. information about LSPs of a specified incoming label. The value is an integer ranging from 0 to 1048575.

Displays information about LSPs of a specified outgoing label. The value is an integer ranging from 0 to 1048575.

4. will not influence.
