EIGRP Protocol Characteristics
Characteristic
EIGRP Support
Distance vector or link
state
Hybrid: distance-vector routing protocol with link-state charac-
teristics
Convergence
Fast convergence with DUAL for a loop-free topology
Classless or classful
Classless routing protocol, supports VLSMs
Scalability
Highly scalable, supports large networks
Multiprotocol support
Supports IPv4, IPv6, plus legacy protocols such as IPX and
AppleTalk
Multicast address for
updates
224.0.0.10 for IPv4; FF02::A for IPv6
