Label acceptance control configuration example

Network requirements
Two links, Router A—Router B—Router C and Router A—Router D—Router C, exist between subnets
1 1.1.1.0/24 and 21.1.1.0/24.
Configure LDP to establish LSPs only for routes to subnets 1 1.1.1.0/24 and 21.1.1.0/24.
Configure LDP to establish LSPs only on the link Router A—Router B—Router C to forward traffic between
subnets 1 1.1.1.0/24 and 21.1.1.0/24.
