I am trying to redistribute EIGRP routes from two AS numbers into OSPF so that my PA can learn the proper routes to the rest of the network, but I am running into a stumbling block since I only have one L3 interface connected to my internal network and the PA firewall will only allow a single OSPF area per interface. The PA is at a remote, unmanned location so I don't have the option of configuring a second interface. Is there a way I can still accomplish my goal without configuring another L3 interface? Here are the details of what I am trying to accomplish. I have two Cisco routers and a PA firewall connected on the same VLAN to a switch. Router #1 has EIGRP 100 configured, which needs to be redistributed to OSPF for the PA to learn. Router #2 has EIGRP 100 and EIGRP 101 configured. The routes from both of these AS numbers need to be redistributed to OSPF for the PA to learn, but I do not want router #1 to learn about the routes from AS 101. I had no problem configuring area 0 to create an OSPF neighbor with router #2 and to have the routes from AS 101 redistributed. When I try to create a new area to distribute the routes from AS 100, the PA requires a different interface than the one used for area 0. I'm using a PA3020 with PANOS 7.1.
