Which two components are needed for a service provider to utilize the LVPN MPLS application? (Choose two.)
- A . The P routers must be configured for MP-iBGP toward the PE routers
- B . The P routers must be configured with RSV
- D . The PE routers must be configured for MP-iBGP with other PE routers
- E . The PE routers must be configured for MP-eBGP to connect to CEs
- F . The P and PE routers must be configured with LDP or RSVP
Suggested Answer: C,E
Explanation:
MPLS Network Protocols
+ IGP: OSPF, EIGRP, IS-IS on core facing and core links+ RSVP and/or LDP on core and/or core facing links ->
+ MP-iBGP on PE devices (for MPLS services), MP-BGP: Multiprotocol Border Gateway Protocol,
used for MPLS L3 VPN -> .
