Default Gateway on Client Server Network
Is it allowed to define a Default Gateway on Client Server Network in 800xA.
Does it cause any performance issues? I know it is allowed to define Default Gateway for nodes that does not have RNRP. But does RNRP interfere if Default Gateway is defined on all nodes in 800xA system on the client server network.
It is OK as the only thing you theoretically do is making it possible to reach outside the own subnet.
Declaration can be made either:
1) Via traditional method on NIC IP-settings
2) Via RNRP
The second method offer redundancy. The RNRP service will continuously monitor the primary external gateway and replace it with the secondary in case the primary stop responding on ping.
AFAIK, RNRP will not interfere if Default Gateway is defined on all nodes in 800xA system on the client server network.
Default gateway is generally used for Layer 3 communication.
Gateway defined in client network should be configured in Layer 3 switch also in order to communicate with other XA or Non-XA systems.
