A service provider is receiving BGP routes from a customer that include a route for 127.0.0.0/8. This route is causing routing loops in the provider's network. What is the most effective way to prevent this route from being installed?

Configure the BGP neighbor to not advertise routes in the 127.0.0.0/8 range.

Configure a route filter to reject 127.0.0.0/8 and apply it to the BGP import policy.

Configure a static route for 127.0.0.0/8 with a next hop of discard.

Configure a firewall filter to drop packets destined to 127.0.0.0/8.

What is the primary characteristic that makes an IP address a Martian address?

It is a private address that is used only within a single organization.

It is an address that has been manually configured on a router but is not advertised.

It is assigned to a device that is not yet connected to a network.

It is not valid on the public Internet because it is reserved or special-use.
