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
11.1.1.0 / 24 a n d 21.1.1.0 / 24 .
Configure LDP to establish LSPs only for routes to subnets 11.1.1.0 / 24 a n d 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 11.1.1.0 / 24 a n d 21.1.1.0 / 24 .
