Cisco vs Juniper diffs

IOS ADs Vs JUNOS Preferences

Description Juniper Cisco Huawei
Directly Connected 0 0 0
Static Route 5 1 60
EBGP 170 20 255
EIGRP Not Supported 90 Not Supported
IGRP Not Supported 100 Not Supported
OSPF 10 110 10
IS-IS 160 115 15
RIP 100 120 100
IBGP 170 200 255
OSPF ASE 150 - 150




Based from the above values, one may conclude that Juniper and Huawei has almost the same route preferences. The only difference is the route preference on OSPF and Static Route. Huawei preferred OSPF over Static routes, whereas JunOS and IOS preferred Static Routes over OSPF.

For the route preference on eBGP and iBGP, JunOS has the same value for both routes but according to them, eBGP is always preferred over iBGP.
