NEW QUESTION # 146
In an operator's MPLSVPN network, there are two devices, PE1 and PE2, for MPLSVPN data forwarding. PE1 receives a 172.16.1.0/24 private network route from the client, and transforms it into a VPNv4 route on PE1 and assigns labels. Released to PE2 as 1027. The outgoing label of the MPLSLSR-ID from PE2 to PE1 is 1025.
When the client on PE2 accesses 172.16.1.0/24, the inner and outer labels of the frame sent by PE2 should be the combination of the following options?
- A. Outer label: 1025, inner label: 1025
- B. Outer label: 1025, inner label: 1027
- C. Outer label: 1027, inner label: 1027
- D. Outer label: 1027, inner label: 1025

IGP converges faster than BGP, which may cause network traffic loss. By enabling the OSPF and BGP linkage feature of the device, the device can keep the OSPF and BGP linkage during the set linkage time.____The router makes the link metric value in the LSA advertised to be the maximum value, so as to inform other OSPF devices not to use this router to forward data, so as to avoid traffic loss. (Note: If English letters are involved, all uppercase)
