Question#28

An engineer configured a company's multiple area OSPF Head Office router and Site A Cisco routers with VRF lite. Each site router is connected to a PE router of an MPLS backbone:

Head Office & Site A -
ip cef
ip vrf abc
rd 101:101
!
interface FastEthernet0/0
ip vrf forwarding abc
ip address 172.16.16.X 255.255.255.252
!
router ospf 1 vrf abc
log-adjacency-changes
network 172.16.16.0 0.0.0.255 area 1
After finishing both site router configurations, none of the LSA 3, 4, 5, and 7 are installed at Site A router.
Which configuration resolves this issue?

  • A. configure capability vrf-lite on Site A and its connected PE router under router ospf 1 vrf abc
  • B. configure capability vrf-lite on both PE routers connected to Head Office and Site A routers under router ospf 1 vrf abc
  • C. configure capability vrf-lite on Head Office and its connected PE router under router ospf 1 abc
  • D. configure capability vrf-lite on Head Office and Site A routers under router ospf 1 vrf abc
