Unit 1: Network Infrastructure
This will allow you to demonstrate your networking skills, knowledge, and abilities, with a focus on enterprise-level switching, routing, and multicast components that support cross-platform (inter)operability and integration with the most recent software-defined technologies.
While the Open Shortest Path First (OSPFv3) routing protocol was developed with IPv6 networks in mind, it is possible to make it work with IPv4 networks by utilizing address families. Enabling cross-IPv6 communication is an additional benefit of configuring OSPFv3 on routers. With this, an OSPFv3 instance can hold both IPv4 and IPv6 routing tables, facilitating an easy upgrade to IPv6 in a mixed-network setting.
To accommodate several address families, OSPFv3 modifies the router link state address (LSA) to use the IPv4 reserved range (64–95) instead of the IPv6 reserved range. This enables OSPFv3 to link local addresses while still making use of IPv6 capabilities, allowing it to operate over an IPv4 network. Since both protocols can coexist in the same network, this pliability facilitates a seamless upgrade from IPv4 to IPv6. OSPFv3 is a flexible and versatile routing protocol that can handle networks with different levels of complexity.
In order to configure OSPFv3, all that is required is to activate IPv4 capabilities. Take into account the following actions:
