Alvarion BreezeNET B130/B300 GigE 148 Operational User Manual
If a sequential number is not specified the router sets it up automatically by
adding 5 to the number of the last operator in a list. Thus, the operator will have
the biggest number and will be placed in the end of the list.
4.7.6 Link State Advertisement
The router can advertise its link states of two types:
1 Internal links. These are links which destinations are addresses of the subnets
to which a router is connected directly (using one of its network interfaces) and
which are described in OSPF router configuration.
2 External links. Links which destinations are route's destinations configured in
WANFleX. These can be static routes (route add (kernel)) or routes which
appear in the routing table by assigning IP-address (alias) to one of physical
network interfaces (connected).
In order to advertise an internal link, a subnet should be specified which
destination is an advertised link. This can be done in config-router mode:
network A.B.C.D/M area (A.B.C.D|<0-4294967295>)
Network is specified by router's IP-address/mask which belongs to this network.
Area ID can be inputted either in IP-addresses format or in decimal number
format.
Example:
OSPF>configure
OSPF(config)# router
OSPF(config-router)# network 4.7.8.32/24 area 0.0.0.1
OSPF(config-router)# network 192.168.15.1/24 area 0
OSPF(config-router)#
If none of router's network interfaces has an IP-address from specified subnet,
OSPF will not advertise this link although this network will be in configuration
(inactive link).
Thus, the router obtains an internal link (for OSPF system) for which a given
network is a destination. If this network is a physical interface address
(point-to-point) the router gets an internal link with a router ID destination which
is connected on the opposite end of point-to-point link.
To cancel internal link advertising use the command:
no network A.B.C.D/M area (A.B.C.D|<0-4294967295>)
