Regarding the LDP/BGP/IGP configuration, please refer to this blog.
Here is the topology:
Here we have 2 pseudowires: ce1-ce2-pw4-vlan-301 and ce1-ce2-pw4-vlan-302 to L2 connectivity between CE1 and CE2 across LDP cloud. From CEs' perspective, the pw works like a directly connected L2 link. So the VLANs are in same subnet and running IGPs (OSPF/ISIS) on the top of it.

For the CE's configuration, please note that I use VRF on CE to simulate multiple hosts.
