Guys I have a simple PPPoE setup - client and Server.
Problem is client doesn't assign any labels to the received routes from
server.
I tried 12.3T, 12.4 and 12.4T, all have same problem.
Any thoughts what's wrong? Appreciate any help.
Details -
Topology: (Lo0-2.2.2.2)-Client
-------------PPPoE+MPLS---------------Server-(Lo0-1.1.1.1)
DHCP is used for address allocation for client.
OSPF is used for routing. Routing part is all fine. Routes are exchanged
properly.
Client receives the Server's loopback via OSPF.
LDP neighborship forms between the Client and Server.
But client doesn't assign any label to the received Server's looback
(1.1.1.1).
