The iBGP peer relationships are established using Loopback0 on each router, and the router ID is 10.0.0.X/32, where X is the number of the router. R1 and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import- route command.

Inconsistent area codes

Inconsistent area types

The IP address mask of the interface is inconsistent

The interval for sending Hello packets is inconsistent

NO.50 As shown in the figure, the entire network of a certain company uses OSPF to get through the network. However, RouterS and RouterE cannot establish an OSPF neighbor relationship. When detecting OSPF failures, network administrators can execute the display ospf 100 () interface GEO/0/1 command on RouterS to obtain error-related information. Users can perform OSPF failure diagnosis based on this information. (Please use English lowercase letters to complete the command, and the command cannot be abbreviated)
