After a network topology change occurs, which distance vector routing protocol can send an update message directly to a single neighboring router without unnecessarily notifying other routers?
- IS-IS
- RIPv2
- EIGRP
- OSPF
- RIPv1
Explanation: RIPv2 and EIGRP support updating neighboring routers via the use of multicasting. EIGRP is the only distance vector protocol that can support updating a specific neighbor by using unicast. OSPF and ISIS are link state protocols.
