Enabling IPv6 router discovery in z/OS® Communications Server requires no additional z/OS Communications Server configuration. All that is needed is at least one IPv6 interface that is defined and started, and at least one adjacent router through that interface that is configured for IPv6 router discovery. If these things exist, then z/OS Communications Server begins receiving router advertisements from the adjacent routers. Depending on the configuration in the adjacent routers, the following types of routes can be learned from the received router advertisements:
If a stack routing table contains non-replaceable static routes to a destination, any route to that destination that is learned from a router advertisement is not added to the stack routing table.
