Solved: Re: ospf external path selection with different metric.

syjeon · ‎05-24-2018

Hi,

we are planning to put the another circuit for backup traffic replication purpose between two datacenter.

there is already normal MPLS circuit, so, another 10G circuit will be installed between two datacenter.

my intention is to configure different metric when BGP external routes redistributed into OSPF on two BGP routers.

when I tested, I checked lower metric is preferred to select the routing path always.

I think it is working as my original plan. Can someone review the attached diagram and give me thought so we are fine with this approach to go?

Hello

This is a good solution we use this a lot in duel isp peerings - the majority of the times we tend just to receive only a default from the ebgp pears and distribute a ospf default into the L3 cores with a preferred lower ospf metruc type for the primary path .wirkd a treat!
