Module: IP-INTERFACE-MANAGEMENT-MIB
OID (symbolic): IP-INTERFACE-MANAGEMENT-MIB::cjnIpIfBootpDhcpGateway
OID (numeric): 1.3.6.1.4.1.1751.2.43.3.1.1.2.1.15
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-create
Description: Enable or disable the designation of this interface as that which will 'receive' BOOTP/DHCP requests with a source IP address of 0.0.0.0. This is used on a multinetted interface when it is otherwise ambiguous as to which interface 'receives' the request, and is important because the IP address of the receiving interface is inserted into the giaddr field of the request before the request is relayed to the BOOTP/DHCP server.
If this attribute is disabled, then: - if only one IP interface exists on a VLAN, that IP address is inserted into the request - if more than one IP address exists on a VLAN, the router will choose an interface
If more than one IP interface on a given VLAN has this attribute enabled, the router will choose an interface among those with the attribute enabled.
What is cjnIpIfBootpDhcpGateway?
This object enables or disables this interface as the one that 'receives' BOOTP/DHCP requests with a source IP of 0.0.0.0 on a multinetted VLAN, controlling whose IP address gets inserted into the giaddr field before relaying to the DHCP server. Admins enable this on a specific interface when a VLAN has multiple IP interfaces and it would otherwise be ambiguous which one's address the DHCP relay should use. Enabling this on one of several IP interfaces sharing a multinetted VLAN ensures that interface's address is consistently used as the DHCP relay gateway address for that VLAN.
