ospf equal-cost route

[martin_lx1980]

In cisco document:By default, OSPF keeps up to four equal cost route entries in the routing table for load balancing.

I want to know if more than 4 equal-cost route exist, which 4 routes will be chose and what factor will be considered besides cost?

Hi Martin,

For intra-area routes, paths which are discovered first during SPF get the preference.

For type3/5/7, routes advertised by higher router-id will get the preference.

HTH,
