EIGRP är ett distance vector routing protokoll med en del karaktär av link state protocol. EIGRP använder ett eget protokoll på lager 4, Reliable Transport Protocol. För topologiuträkningar används DUAL.
Contents
Databaser
- Neighbor table
- Topology table
- Routing (Forwarding) table
Adjacency
- Hello packet - Multicast 224.0.0.10, every 5 seconds.
- AS nummer måste vara samma på alla routrar.
- K values need to match in EIGRP AS domain in order for neighbours to form
Metric
- k1 = bandwidth
- k2 = load
- k3 = delay
- k4 = reliability
- k5 = MTU
Simplified default metric = bandwidth + delay
Konfiguration
router eigrp [ASN]
Manually set ID
eigrp router-id [ip-address]
Add networks to advertise
network [ip-address] [wildcard-mask]
Disable automatic route summarization (Default sedan IOS 15)
no auto-summary
Designate passive interfaces
passive-interface [interface]
Statically identify neighoring routers
neighbor [ip-address] [interface]
MD5 authentication
interface [interface] ip authentication mode eigrp md5 ip authentication key-chain eigrp [ASN] [name-of-chain]
