Example - Owner Virtual Router Instance
Non-Owner Virtual Router IP Address Parental Association — When an IP address is
assigned to a non-owner virtual router instance, it must be associated with one of the parental IP
interface assigned IP addresses. The virtual router IP address must be a valid IP address within one of
the parental IP interfaces local subnet. Local subnets are created by the primary or secondary IP
addresses in conjunction with the IP addresses mask. If the defined virtual router IP address is equal
to the associated subnet's broadcast address, it is invalid. Virtual router IP addresses for non-owner
virtual router instances that are equal to a parental IP interface IP address are also invalid.
The same virtual router IP address may not be assigned to two separate virtual router instances. If the
virtual router IP address already exists on another virtual router instance, the virtual router IP address
assignment will fail.
Example - Non-Owner Virtual Router Instance
Virtual Router IP Address Assignment without Parent IP Address — When assigning an
IP address to a virtual router instance, an associated IP address (see Owner Virtual Router IP
Address Parental Association and Non-Owner Virtual Router IP Address Parental Association)
on the parental IP interface must already exist. If an associated IP address on the parental IP interface
is not configured, the virtual router IP address assignment fails.
