I am thinking whether it is possible to build a label switching network by underlying the bgp-labeled-unicast label in a public Internet environment.
A--ebgp--B--iBGP--C--ebgp--D--iBGP--E--eBGP--F;
In the given elaborated end-to-end connectivity network in the above, there are 6 routers from A to F, where the routers B and C belong to the ISP AA, the routers D and E belong to the ISP BB, and the routers A and F belong to the customer CC. All routers use public IP address.
Is it possible to build a BGP-labeled-unicast network from A to F for the customer CC by multiple-hops eBGP from ingress router A to egress router B?
I have read the RFC 3107 (https://tools.ietf.org/html/rfc3107)
I understand the BGP labeled-switching means that the label switching must be engaged into all routers from A to F, but as the perspective from the customer CC, it is unknown and out-of-control to CC that the ISP AA and BB should reject the customer CC to act BGP-Labeled-Unicast label switching, however if the talented engineers in this Forum can have better or other ideas to achieve this non-standard demand for A - F MPLS design. Appreciate it in advanced!
