The values between juniper and Cisco are very similar. The default values are a little slower with Juniper in some areas such as IS-IS and OSPF (intermediate system to immediate system and open shortest path first).
3. The OSPF routes (open shortest path first) in Cisco has no hop count limitations. The external for Cisco (EBGP) is 20 compares to Junos (BGP) with 170. Cisco is lower because it goes out as a AS instead of staying as a AS. The IBGP is 200 because of its internal route should be a IGP. The
