質問 # 125
Fill in Blanks
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)
