Due to recent acquisitions, a company’s MPLS infrastructure is growing very quickly. Concerns arise about labeling each and every IP address on the service provider core network. The IP address space is designed as per following:
. Service provide ip address range is: 10.0.0.0/16
. All loopback addresses use subnet mask /32
. 10.0.0.0/24 range is used for loopback addresses
. All other subnet masks used for links are /24 and /25
Which command would significantly reduce the label allocations without compromising LDP functionalities?
A. ip prefix-list Llst1 deny 10.0.0./16 le 20 ge 25
!
mpls Idp label
allocate global prefix-list List1
B. access-list 1 permit 10.0.0.0 0.0.255.255
mpls Idp neighbor 10.0.0.1 labels accept 3
C. mpls Idp label
allocate global host-routes
D. mpls Idp password required for 10
!
access-list 10 permit 10.0.0.1
access-list 10 permit 10.0.0.2
access-list 10 permit 10.0.0.3
