we use ospf in our network for routing and changed the default bandwith with the command
ospf auto-cost reference-bandwidth 10000
After that, the cost for a Gigabit-Interface counts to 10 as expected, for 100MB-interfaces it
counts 100 and for TenGigabit it goes to 1.
Fine so far, however, when we look at the networks routed through the TenGig-Interfaces, they
still have cost of 10.
I remeber a cisco-document where it is explained that for vlans the cost is left 10 after changing
the reference bandwidth and one should manually change that via "ospf cost 1" - when having a
Does somebody know docs from cisco regarding that topic? is it a bug? May i change the cost
of the vlan intercae without having downtime?
Thanks for advance for your help,
