Label acceptance control configuration example

Network requirements
Two links, Switch A—Switch B—Switch C and Switch A—Switch D—Switch C, exist between subnets
1 1.1.1.0/24 and 21.1.1.0/24.
Configure label acceptance control, so LDP sets up LSPs only on the link Switch A—Switch B—Switch C
to forward traffic between subnets 1 1.1.1.0/24 and 21.1.1.0/24.
