Does anyone know exactly how the ospf sham-link operates. By default bgp learned routes do not get a label assigned (only the next hop). OSPF sham-link host interfaces MUST be advertised by BGP and not the ospf process. This says to me that the sham-link CANNOT be lable switched throughout the core network. However every document not very clearly always states the sham-link will follow the label forwarding table.
The source and destination IP addresses
must belong to the VRF and be advertised by Border Gateway Protocol (BGP) to remote PE routers. The
sham-link endpoint addresses should not be advertised by OSPF.
Anyone any decent explanation of why this is.
