M telecom network operator wants to extend its OMC LAN to a remote location say location B so that it can maintain NGN equipment present at location A. Location A and B are connected to gether with AR46-80 routers using E1 links. Both routers are running OSPF and are in Area 0. The O&M termial IP subnet is 10.0.0.0/24.
There is another local LAN in location B from which the operator wants to access location A. So we plan to connect AR46 with operator's LAN switch using ethernet link. The LAN switch is from company C so we donot want to run OSPF directly with C company equipment. The problem is that , the operator is running OSPF in their LAN in locatoin B and NGN is also running OSPF in location A and we have to integrate both locations.
1) Create a VLAN in C-LAN switch, make VLAN interface and assign one IP address.
2) Assign IP address on FE port of AR46-B router so that they can ping each other.
3)On AR46 router in location B, configure a static route towards the operators LAN segment with next hop as C-LAN switch's VLAN interface.
4) on C-LAN switch configure a static route for LAN of location A with nexthop as FE interface on AR46-B.
5) Redistribute this static route in both OSPF, on C-LAN switch OSPF and also on AR46-B OSPF.
After this configuration, the problem was solved and both LAN segments are integrated.
OSPF protocol is running on both LAN segments at location A and in location B and we can not run OSPF between Huawei AR46 and C-LAN switch. so we have to use static routing and then import static routes in OSPF. on both LANs
