In one embodiment, an apparatus includes a first transport stack, a virtual network interface controller (VNIC), and a second transport stack. The first transport stack is associated with an Internetwork Operating System (IOS), as well as with a plurality of interface-based Internet Protocol (IP) addresses and a plurality of IP addresses. The VNIC is configured to dynamically provision the plurality of interface-based IP addresses and the plurality of IP addresses. The second transport stack is associated with a kernel, and configured to communicate with a first application. The MS is configured to enable the first application to share the plurality of IP addresses and the plurality if IP addresses with a plurality of applications.

Enabling applications in a multi-transport stack environment

A method and apparatus is disclosed for graceful restart in a multi-process operating system. A transport protocol process, which is capable of restarting independently from the operating system, is executed in a network element. The network element executes a Border Gateway Protocol (BGP) process, which installs one or more routes in a global Routing Information Base (RIB). When the BGP process detects that the transport protocol process has become unavailable, the BGP process keeps the one or more routes in the global RIB even though the transport protocol process is not available.
