문제9

OSPFv2 is an IGP that runs on IPv4 networks. OSPFV3 is an IGP running on IPv6 networks. Compared with OSPFv2, OSPFv3 has similar LSAs, but has slightly different functions.
The following is the description of the LSA function of OSPFV3, please drag the LSA to the correct LSA function column.

정답:

문제10

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

A. STUB
