4. Configure IPv4 LSP generation policies:
# On Switch A, create IP prefix list switcha, and configure LDP to use only the routes permitted
by the prefix list to establish LSPs.
[SwitchA] ip prefix-list switcha index 10 permit 11.1.1.0 24
[SwitchA] ip prefix-list switcha index 20 permit 21.1.1.0 24
[SwitchA] mpls ldp
[SwitchA-ldp] lsp-trigger prefix-list switcha
[SwitchA-ldp] quit
# On Switch B, create IP prefix list switchb, and configure LDP to use only the routes permitted
by the prefix list to establish LSPs.
[SwitchB] ip prefix-list switchb index 10 permit 11.1.1.0 24
[SwitchB] ip prefix-list switchb index 20 permit 21.1.1.0 24
[SwitchB] mpls ldp
[SwitchB-ldp] lsp-trigger prefix-list switchb

# On Switch C, create IP prefix list switchc, and configure LDP to use only the routes permitted
by the prefix list to establish LSPs.
[SwitchC] ip prefix-list switchc index 10 permit 11.1.1.0 24
[SwitchC] ip prefix-list switchc index 20 permit 21.1.1.0 24
[SwitchC] mpls ldp
[SwitchC-ldp] lsp-trigger prefix-list switchc

# On Switch D, create IP prefix list switchd, and configure LDP to use only the routes permitted
by the prefix list to establish LSPs.
[SwitchD] ip prefix-list switchd index 10 permit 11.1.1.0 24
[SwitchD] ip prefix-list switchd index 20 permit 21.1.1.0 24
[SwitchD] mpls ldp
[SwitchD-ldp] lsp-trigger prefix-list switchd

5. Configure IPv4 label acceptance policies:
# On Switch A, create IP prefix list prefix-from-b to permit subnet 21.1.1.0/24. Switch A uses
this list to filter FEC-label mappings received from Switch B.
[SwitchA] ip prefix-list prefix-from-b index 10 permit 21.1.1.0 24
# On Switch A, create IP prefix list prefix-from-d to deny subnet 21.1.1.0/24. Switch A uses this
list to filter FEC-label mappings received from Switch D.
[SwitchA] ip prefix-list prefix-from-d index 10 deny 21.1.1.0 24
# On Switch A, configure label acceptance policies to filter FEC-label mappings received from
Switch B and Switch D.
