AS. A common practice is to set the router ID to the IP address of an interface on the
router.
Enabling OSPF
VRP (versatile routing platform) supports multiple OSPF processes. To enable
multiple OSPF processes on a router, you need to specify different process IDs.
OSPF process ID is only locally significant; it does not affect the packet exchange
between an OSPF process and other routers. Therefore, packets can be exchanged
between routers with different OSPF processes IDs.
Configuring an area and the network segments in the area. You need to plan
areas in an AS before performing the corresponding configurations on each
router.
When configuring the routers in the same area, please note that most configurations
should be uniformly made based on the area. Wrong configuration may disable
information transmission between neighboring routers and even lead to congestion or
self-loop of routing information.
