Netgear XCM8806 - 8800 SERIES 6-SLOT CHASSIS SWITCH ユーザーズマニュアル

Two types of OSPFv3 functionality are available and each has a 

different licensing requirement. One is the complete OSPFv3 
functionality and the other is OSPFv3 Edge Mode, a subset of 
OSPFv3 that is described below. See 

 for specific information regarding OSPFv3 

licensing.

OSPFv3 Edge Mode

OSPFv3 Edge Mode is a subset of OSPFv3 available on platforms with an Advanced Edge 
license. There are two restrictions on OSPFv3 Edge Mode:

At most, four Active OSPFv3 VLAN interfaces are permitted. There is no restriction on the 

number of Passive interfaces.

The OSPFv3 Priority on VLANs is 0, and is not configurable. This prevents the system 

from acting as a DR or BDR

Link State Database

Upon initialization, each router transmits a link state advertisement (LSA) on each of its 
interfaces. LSAs are collected by each router and stored into the LSDB of each router. After 
all LSAs are received, the router uses the LSDB to calculate the best routes for use in the IP 
routing table. OSPFv3 uses flooding to distribute LSAs between routers. Any change in 
routing information is sent to all of the routers in the network. All routers within an area have 
the exact same LSDB.
