Dual Trunk E1 Router
Dual Trunk E1 Router User’s Guide TECHNICAL: 0118 96 56 000 179
Command Mode
Router mode
Usage
The address and mask define interfaces to be associated with a specific OSPF area. The primary address of the interface should be
covered by the network area command. Covering only the secondary address does not enable OSPF over that interface.
The mask is used as a shortcut and it helps putting a list of interfaces in the same area. The mask contains wild card bits where 0
is a match and 1 is a don't care bit. For example, 0.0.0.255 is a match in the first three bytes of the network number.
Any individual interface can only be attached to a single area. If the address ranges specified for the different areas overlap, the
software will adopt the first area in the network command list and ignore the subsequent overlapping portions.
Specify address ranges that do not overlap.
Examples
ospfd# configure terminal
ospfd(config)# router ospf 100
ospfd(config-router)# network 10.0.0.0/8 area 3
ospfd(config-router)# network 10.0.0.0/8 area 1.1.1.1

Command Syntax
opaque (link|area|as) WORD TYPE ID DATA
link flood opaque-LSA to link-local scope. i.e. the LSA is not flooded over any routers.
area flood opaque-LSA to single area. i.e. the routers in the same area should have the LSAs.
as flood opaque-LSA to whole AS. i.e. the routers in the single AS should have those LSAs.
WORD = if scope is link, WORD is an interface address.
if scope is area, WORD is an Area-ID.
if scope is as, WORD should be ignored.
TYPE = <0-256> Opaque type which is maintained by IANA.
ID = <0-16777216> Opaque ID which is the value specific to the Opaque type.
DATA = Actual Opaque Information which is stored into packet body of Opaque LSAs.
