1. SSH should only be configured on Branch_1.
2. Use the domain name cisco.com on Branch_1.
3. The username should be admin, password should be class.
4. Use 1024 bits and the more secure version of SSH.
5. Configure all VTY lines to use the local user database for authentication.

Routing requirements:

1. There should be a default route on Edge pointing towards ISP using the next-hop method. This route should be shared to all other devices participating in OSPF. (Do not share the public address 50.0.0.0/30 over OSPF, as this is not best practice.)
2. ISP should have a default route pointing towards Edge using the next-hop method. No dynamic routing should be configured on ISP router.
3. Configure OSPF between all routers (Edge, HQ_1, HQ_2, & Branch_1). Use PID 1.
4. Apply passive interface where appropriate
