Hello Harold,

I thought that the usage of the command bgp always-compare-med was enough to achieve the intended result.

From

http://www.cisco.com/en/US/docs/ios/iproute/command/reference/irp_bgp1.html#wp1011748

To enable the comparison of the Multi Exit Discriminator (MED) for paths from neighbors in different autonomous systems, use the bgp always-compare-med command in router configuration mode. To disallow the comparison, use the no form of this command.

Actually, I haven't tried what I was suggesting.

Thanks for your correction.

Best Regards

Giuseppe

Giuseppe,

This command will only force the comparison of MEDs between different ASes. It doesn't mean both paths will be installed if the MEDs are equal.

You absolutely need the hidden command "bgp bestpath as-path multipath-relax" to get the two paths to be installed in the RIB.

Regards,
