Since Loopback interfaces are virtual, they cannot go down, thus preventing changes in the router ID. If no Loopback interfaces are configured, the highest IP address of any interface is used as the router ID. To view the status of BGP neighbors, use the show ip bgp neighbors (Figure 8-14) command in EXEC Privilege mode. For BGP neighbor configuration information, use the show running-config bgp command in EXEC Privilege mode (Figure 8-15). Note that the showconfig command in CONFIGURATION ROUTER BGP mode gives the same information as thew show running-config bgp. 158 | Border Gateway Protocol IPv4 (BGPv4)
