  !RouterA/BranchA ip as-path access-list 1 permit ^$ ! router bgp 65000 address-family ipv4 unicast neighbor 1.1.1.1 filter-list 1 out The above config would prevent BranchA from becoming a transit AS by only advertising locally learned routes upstream to HQ. So according to HQs routing table, the only way to get to BranchB is through MPLSB.

  The provided answer is correct. For D, MPLS is working with iBGP. Don't know how to use AS_PATH filter.
