Current Setup
Two separate networks a gigabit Ethernet network configured with a Cisco 6509 switch which segments the network using vlan networks 10.20.0.0/22 and an ATM flat network 10.10.0.0/16. A nokia firewall is being used to bridge the two networks.
This is done by running OSPF between the networks and creating a dedicated network between core switch and firewall (10.1.0.0/24). The firewall is the gateway of last resort to the internet and also for users on the 10.10.0.0/24. The firewall IP address is 10.10.1.1
Objective:
• To have all one network that is all users on the 10.20.0.0/22
• The migration process was started however the firewall is intermittently dropping connectivity between the two networks.
• Allow the core switch to perform routing for users on the 10.10.0.0/16 network, until all users are migrated to the 10.20.0.0/22.Thus reducing the load on the firewall.
How do I configure the 6509 switch to route the 10.10.0.0/18 network and make the firewall the gateway of last resort?
