Which protocol would a PE router use to support an existing Internet routing scheme?

BGP VPNv4
IS-IS
BGP IPv4
EIGRP

Explanation: While PE routers use MP-BGP (VPNv4/VPNv6) for internal customer VPN routes, they must also support traditional Internet connectivity. The sources state that PE routers can run standard IPv4 BGP in the global routing table to exchange Internet routes with other PE routers, ensuring support for existing Internet routing schemes.
