IP Multipathing (IPMP) in Sun Solaris enables the load balancing capabilities and resilience for Network connections with multple Network Interface Cards (NIC). I discussed here about providing resilience for network connections with multiple NICs on the system. Now, we take it to the next step and make the network connections not only resilient but also

In SPARC Servers running Sun Solaris, you can see multiple Network Interface Cards (NICs) or interfaces are all sharing a single MAC-Address than having a unique Factory-default MAC-Address assigned to it. This is because by default, a System-Wide MAC-Address is assigned to all the NICs and hence a ifconfig -a output will show only one

IP Multipathing (IPMP) in Sun Solaris enables the load balancing capabilities and resilience for Network connections with multple Network Interface Cards (NIC). IPMP is mostly used to provide resilience with network connections wherein a Sun Solaris Server with multiple NICs can be configured such that if the primary NIC fails it automatically failover to the

The Default Gateway or the Default Router is the IP address (IPv4) to which all the traffic to any target destination(s) which does not have a route in the Routing Table of the server will be forwarded. This Default Gateway is maintained in the file /etc/defaultrouter [IPv4 only]

To add a Static Route in Sun Solaris operating system, you can use the route command. This will dynamically update the Kernel IP Routing table. However, when a server is restarted, these routes will be lost. To prevent this from happening, add a startup script S76static-routes with all the route commands for the static route
